10	Weak OTP — 3-digit, `rand()`, no rate limiting	Account takeover	🔴 CRITICAL

🔴 SECTION 1: CRITICAL VULNERABILITIES (26)

C-01: Live Secrets Committed to Git (P1)

Files: siro_admin/.env, siro_service/.env, backend/.env.example

Severity: CRITICAL

Details: Both siro_admin/.env and siro_service/.env contain live production secrets including:

privateKeyFCM — Firebase Cloud Messaging private key (server-only credential)
basicAuthCredentials — Basic auth credentials for internal services
mapAPIKEY (AIzaSyCFsWBqvkXzk1Gb-bCGxwqTwJQKIeHjH64) — Google Maps API key
authTokenTwillo — Twilio authentication token
chatGPTkey, chatGPTkeySefer, chatGPTkeySeferNew — OpenAI API keys
geminiApi, geminiApiMasa — Google Gemini API keys
secretKey — Application JWT/encryption secret
payPalClientIdLive, payPalSecretLive — PayPal live credentials
payMobApikey, usernamePayMob, passwordPayMob — Payment gateway credentials
agoraAppId, agoraAppCertificate — Agora voice/video credentials
whatsapp — WhatsApp Business API access token
claudeAiAPI, anthropicAIkeySeferNew — Anthropic Claude API keys
llamaKey, llama3Key — LLM API keys
cohere, visionApi — Additional AI API keys
stripe_publishableKe — Stripe publishable key
keyOfApp, initializationVector — Encryption key/IV
Private Firebase service account key (embedded in privateKeyFCM)

Impact: Any attacker with repo access has full API access to 15+ external services, can send SMS/Twilio messages, send push notifications, charge PayPal accounts, and decrypt the entire application database.

No .gitignore file exists, meaning all these files are tracked by Git.

C-02: RSA Private Keys in Repository (P1)

Files:

walletintaleq.intaleq.xyz/v2/main/ride/mtn/driver/private_key.pem
walletintaleq.intaleq.xyz/v2/main/ride/mtn/passenger/private_key.pem
walletintaleq.intaleq.xyz/v2/main/ride/mtn/driver/public_key.pem
walletintaleq.intaleq.xyz/v2/main/ride/mtn/passenger/public_key.pem

Severity: CRITICAL

Details: RSA private keys for MTN mobile money integration are committed to the Git repository. Driver and passenger keys are identical. Anyone with repo access can:

Decrypt MTN API traffic
Forge payment confirmations
Impersonate the payment terminal to MTN's API
Sign arbitrary requests

Fix: Remove keys from repo immediately, rotate keys on MTN side, use a secrets manager (AWS Secrets Manager, HashiCorp Vault).

C-03: Pervasive IDOR — JWT Identity Ignored Across All Endpoints (P1)

Files (representative sample):

backend/ride/rides/add_ride.php — $passenger_id from POST, not JWT
backend/ride/rides/acceptRide.php — $driverId from POST, not JWT
backend/ride/rides/finish_ride_updates.php — $driver_id, $passengerId from POST
backend/ride/cancelRide/add.php — $driverID, $passengerID from POST
backend/ride/rate/add.php — $passenger_id, $driverID, $rideId from POST
backend/ride/rate/addRateToDriver.php — $passenger_id, $driver_id from POST
backend/ride/invitor/add.php — $driverId from POST
backend/ride/invitor/claim.php — $driverId, $passengerId from POST
backend/uploadImagePortrate.php — $driverID from POST
backend/ride/driverWallet/add.php — $driverId from POST
walletintaleq.intaleq.xyz/v2/main/ride/passengerWallet/add.php — $passenger_id from POST
walletintaleq.intaleq.xyz/v2/main/ride/payment/updatePaymetToPaid.php — $driverID from POST

Severity: CRITICAL

Impact: While connect.php properly authenticates users via JWT and populates $user_id and $role, almost every downstream endpoint ignores these and reads user identifiers from request parameters. This means:

Any authenticated user can create rides as any passenger
Any user can accept rides as any driver
Any user can finish rides for any driver/passenger pair
Any user can overwrite any driver's profile image
Any user can submit ratings for any driver/passenger/ride
Any user can claim referral rewards for any driver
Any user can credit/debit any wallet

This is the single most critical architectural flaw in the application.

C-04: No Role-Based Access Control on Admin Endpoints (P1)

Files:

backend/Admin/AdminCaptain/get.php — Returns ALL drivers with full PII + FCM tokens
backend/Admin/rides/admin_get_rides_by_phone.php — Returns any user's ride history
backend/Admin/rides/monitorRide.php — Live GPS tracking of any driver
backend/Admin/passenger/admin_delete_and_blacklist_passenger.php — Delete any passenger
backend/Admin/passenger/admin_update_passenger.php — Modify any passenger's data
backend/Admin/ride/AdminRide/get.php — View any ride details
backend/Admin/send_whatsapp_message.php — Send WhatsApp via company account
backend/Admin/errorApp.php — Inject arbitrary error records

Severity: CRITICAL

Details: These endpoints include connect.php (JWT auth) but never check $role. Any authenticated user — passenger, driver, service — can access all admin functions. Only dashbord.php enforces a role check.

Impact: A passenger can:

Enumerate all captains' personal data and device tokens
Look up any phone number's ride history
Live-track any driver's GPS position in real-time
Delete and blacklist any passenger account
Send WhatsApp messages at company expense

C-05: Unauthenticated FCM Push Notification Relay (P1)

File: backend/ride/firebase/send_fcm.php

Severity: CRITICAL

Details: This endpoint has zero authentication — no JWT, no API key, no IP restriction. Anyone on the internet can send arbitrary push notifications to any FCM token or topic.

Impact:

Send phishing notifications to all app users
Impersonate the Siro app with fake messages
Drain FCM quota
Send malicious data payloads to trigger app actions

Attack Vector: POST /ride/firebase/send_fcm.php with body {"target": "<topic_or_token>", "title": "Phishing", "body": "Click here"}

C-06: Unauthenticated Payment Webhooks (Wallet) (P1)

Files:

walletintaleq.intaleq.xyz/v2/main/ride/shamcash/save_transactions.php
walletintaleq.intaleq.xyz/v2/main/ride/shamcash/save_transactions_new.php

Severity: CRITICAL

Details: ShamCash payment webhooks process incoming payment notifications and credit user wallets. They have zero authentication — no HMAC signature, no API key, no IP allowlist. The jwtconnect.php is included but its failure is silently ignored (if(isset($con)) break;).

Impact: Anyone who discovers the URL can POST fake transactions and trigger automatic wallet deposits with bonuses — effectively creating money.

C-07: FCM Private Key in Client Apps (P1)

File: siro_driver/lib/env/env.dart (and rider, admin equivalents)

Severity: CRITICAL

Details: The Firebase Cloud Messaging private key is included in all Flutter client apps via the envied package with obfuscate: true. The envied obfuscation is XOR-at-compile-time and trivially reversible — the generated env.g.dart contains both the XOR key and ciphertext.

Impact: Extraction enables sending arbitrary push notifications impersonating the server, phishing users, or triggering malicious actions in-app. FCM private keys are server-only credentials and must never be in client apps.

C-08: PCI DSS Violation — Credit Card Data in Client App (P1)

File: siro_driver/lib/constant/box_name.dart (Lines 87-94)

Severity: CRITICAL

Details: Storage keys for cardNumber, cvvCode, and expiryDate are defined in the app. Storing CVV post-authorization violates PCI DSS Requirement 3.2. Even with FlutterSecureStorage, CVV must never be retained after authorization.

C-09: SQL Injection in Payment Status Update (P1)

File: walletintaleq.intaleq.xyz/v2/main/ride/payment/updatePaymetToPaid.php (Line 7)

Severity: CRITICAL

Code:

$sql = "UPDATE `payments` SET `isGiven`='Paid' WHERE driverID='$driverID'";

Details: $driverID from filterRequest() is interpolated directly into SQL string. Despite using prepare()/execute(), the SQL is fully concatenated with user input, making prepare() useless.

Impact: Full database compromise — read/write any table including payment records, user credentials, wallet balances.

C-10: OTP Weaknesses (P1)

Files:

backend/auth/token_passenger/send_otp.php — Uses rand(100, 999) (3-digit, predictable)
backend/auth/otp/request.php — Uses random_int(0, 999) with str_pad to 3 digits
backend/auth/token_passenger/verify_otp.php — No rate limiting

Severity: CRITICAL

Details:

rand() is a linear congruential generator — cryptographically predictable
3-digit OTP = only 1000 combinations
No rate limiting on token_passenger endpoints
Loose comparison (==) in OTP verification enables type juggling

Impact: OTP brute-forceable within hours. Complete account takeover.

C-11: JWT Parsed Without Signature Verification (Auth) (P1)

Files:

backend/auth/otp/request.php:22-31
backend/auth/otp/verify.php:26-36

Severity: CRITICAL

Details: The JWT Authorization header is base64-decoded (not verified) and the role claim is extracted WITHOUT signature verification. Any attacker can craft a fake JWT with any role.

Impact: Privilege escalation — impersonate any user type without a valid token.

C-12: Storage Backend Mismatch — OTP Verification Always Fails (P1)

Files:

backend/auth/token_passenger/send_otp.php:60-69 — Writes OTP to MySQL
backend/auth/token_passenger/verify_otp.php:31 — Reads OTP from Redis

Severity: CRITICAL (Authentication Broken)

Details: OTP is stored in MySQL table token_verification but verification reads from Redis key otp:passenger:{phone}. Different storage backends means verification always fails. Legitimate users cannot verify their OTP.

C-13: Debug Endpoint with Encryption Oracle + Weak Auth (P1)

File: backend/Admin/debug/ggg.php

Severity: CRITICAL

Details: This debug endpoint:

Does NOT use JWT auth (uses custom connect.php include with CWD-dependent relative path)
Auth is gated only by admin_phone parameter matching ADMIN_PHONE_NUMBERS env var
Provides arbitrary encryption/decryption oracle via $encryptionHelper

Impact: Complete compromise of encryption-at-rest. Attacker can decrypt all PII and encrypt malicious payloads.

C-14: Driver Token Retrieval Without Auth Check (P1)

File: backend/Admin/AdminCaptain/get.php

Severity: CRITICAL

Details: Returns all captain records including FCM device tokens from driverToken table. No role check. FCM tokens enable account impersonation via push notifications.

C-15: Ride History + Live GPS Tracking Without Auth Check (P1)

Files:

backend/Admin/rides/admin_get_rides_by_phone.php
backend/Admin/rides/monitorRide.php

Severity: CRITICAL

Details:

admin_get_rides_by_phone.php — Returns full ride history for ANY phone number
monitorRide.php — Returns live GPS coordinates (lat, lng, speed, heading) of any driver

No role check on either endpoint.

C-16: Admin Debug Endpoints in Production (P1)

Directory: backend/Admin/debug/ (10+ files)

Severity: CRITICAL

Details: Contains scripts for: database connection testing, Redis connection testing, phone debugging, environment variable dumping. Protected only by .htaccess (Apache-specific). If server uses nginx/Caddy, all are publicly accessible.

C-17: Wallet Balance Deduction Without Sufficient Balance Check (P1)

File: walletintaleq.intaleq.xyz/v2/main/ride/payment/process_ride_payments.php:81-94

Severity: CRITICAL

Details: Passenger wallet is debited via negative ledger entry with NO query checking if the passenger has sufficient balance. No SELECT ... FOR UPDATE row lock.

Impact: Passengers can drive wallets arbitrarily negative. Race-condition double deduction.

C-18: Missing FOR UPDATE Row Locks in Payment Processing (P1)

File: walletintaleq.intaleq.xyz/v2/main/ride/payment/process_ride_payments.php:60-130

Severity: CRITICAL

Details: Uses beginTransaction/commit but never SELECT ... FOR UPDATE. Concurrent requests can interleave, enabling race-condition exploitation.

C-19: Client-Controlled Debt/Amount in Payment Processing (P1)

File: walletintaleq.intaleq.xyz/v2/main/ride/payment/process_ride_payments.php:44

Severity: CRITICAL

Code: $passengerWalletBurc = filterRequest("passengerWalletBurc");

Details: Debt settlement amount is provided by the caller (S2S). If the S2S caller is compromised, attacker can settle any amount.

C-20: Race Condition in ShamCash Transaction Processing (P1)

Files:

walletintaleq.intaleq.xyz/v2/main/ride/shamcash/save_transactions.php:45-46
walletintaleq.intaleq.xyz/v2/main/ride/shamcash/save_transactions_new.php:54-55

Severity: CRITICAL

Details: Transaction deduplication uses file-based counter (last_id.txt) with no atomic locking. Under concurrent requests, the same transaction can trigger two wallet deposits.

Impact: Double-spend — create money.

C-21: Encryption Oracle in Client-Side Crypto (P1)

Files: siro_admin/.env, siro_driver/.env, all char_map.dart, encrypt_decrypt.dart

Severity: CRITICAL

Details: Custom substitution cipher (a=q, b=x, c=f, etc.) is used for "encryption." The substitution tables, obfuscation algorithm, and delimiter (BlBlNl) are all in source code. The envied XOR-based obfuscation is trivially reversible.

Impact: All 40+ API keys, credentials, and secrets in the Flutter apps are extractable from the binary via static analysis.

C-22: Static IV in AES-CBC Encryption (P1)

Files:

walletintaleq.intaleq.xyz/v2/main/encrypt_decrypt.php — Static IV from env
siro_admin/lib/controller/functions/encrypt_decrypt.dart — Static IV per env

Severity: CRITICAL

Details: AES-CBC with a static, never-changing IV makes encryption deterministic. Same plaintext always produces same ciphertext. Enables chosen-plaintext attacks.

Impact: All encrypted data (phone numbers, names, emails) is recoverable via known-plaintext attacks.

C-23: Webhook Token Bypass — Any Non-Empty Token Works (P1)

File: walletintaleq.intaleq.xyz/v2/main/jwtconnect.php:96-103

Severity: CRITICAL

Code:

$webhookToken = $_SERVER['HTTP_X_AUTH_TOKEN'] ?? '';
if (!empty($webhookToken)) {
    $authMethod = 'WEBHOOK';

Details: Any non-empty X-Auth-Token header bypasses JWT authentication entirely. No validation of token value — only existence check.

C-24: `siro_service` App Has `allowBackup=true` (Default)

File: siro_service/android/app/src/main/AndroidManifest.xml

Severity: HIGH

Details: android:allowBackup not explicitly set — defaults to true. App data (tokens, keys, database) can be backed up via adb, enabling data exfiltration.

C-25: OTP Replay Attack — No `verified` Status Check

File: backend/auth/otp/verify.php

Severity: HIGH

Details: SELECT queries don't check verified = 0. After first successful verification, same OTP can be reused within expiration window.

C-26: `rand()` for OTP Generation Instead of `random_int()`

File: backend/auth/token_passenger/send_otp.php:6

Severity: HIGH

Details: $otp = (string)rand(100, 999) uses PHP's rand() which is a linear congruential generator. OTPs are cryptographically predictable.

🟠 SECTION 2: HIGH VULNERABILITIES (32)

H-01: Missing `.gitignore` — All Secrets Tracked by Git

File: Root directory — .gitignore does not exist

Severity: HIGH

Impact: Every file in the repository is tracked. .env files, PEM keys, and secrets are permanently in Git history.

H-02: Host Header Injection in Upload Endpoints

Files:

backend/uploadImagePortrate.php:50-52
backend/upload_audio.php:62-64

Severity: HIGH

Code: $host = $_SERVER['HTTP_HOST'] ?? 'api.siromove.com';

Impact: Attacker-controlled Host header generates URLs pointing to attacker servers. Enables SSRF or open redirect.

H-03: Log Injection / Log Forging

File: backend/Admin/errorApp.php:13

Severity: HIGH

Impact: User-controlled input written directly to logs without sanitization. CRLF injection enables fake log entries.

H-04: Information Disclosure — Hardcoded Internal IPs and Paths

Files:

backend/functions.php:23-34 — Internal IPs (http://188.68.36.205:2021, etc.)
backend/encrypt_decrypt.php:7 — /home/siro-api/env/.env
backend/core/helpers.php:230 — /home/siro-api/.internal_socket_key
walletintaleq.intaleq.xyz/v2/main/loginWalletAdmin.php:5 — /home/intaleq-wallet/env/.env
walletintaleq.intaleq.xyz/v2/main/encrypt_decrypt.php:6 — /home/intaleq-walletintaleq/env/.env

Severity: HIGH

Impact: Internal network topology and filesystem paths exposed. Aids targeted attacks.

H-05: User Enumeration via Distinct Error Messages

Files:

backend/auth/signup.php:38 — "already registered" vs success
backend/auth/login.php:53,61 — "User does not exist" vs "Incorrect password"
walletintaleq.intaleq.xyz/v2/main/loginWalletAdmin.php:72-85 — "User not found" vs "Invalid credentials"

Severity: HIGH

Impact: Attacker can enumerate valid phone numbers, emails, and admin usernames.

H-06: User-Supplied Primary Key (`id` field)

File: backend/auth/signup.php:14,49

Severity: HIGH

Impact: Client provides the user ID. No server-side generation. Enables ID collision and IDOR.

H-07: No Input Validation on Phone, Email, or Password

Files:

backend/auth/signup.php:6-14
backend/auth/login.php:5-7
backend/auth/otp/request.php:14-40

Severity: HIGH

Impact: Allows malformed data, weak passwords, injection in downstream systems.

File: backend/auth/login.php:32 — WHERE phone = :phone AND email = :email

Severity: HIGH

Impact: Unintentional AND logic. Login requires both identifiers, breaking phone-only or email-only login flows.

H-09: Fatal Error — Undefined Variable `$conn`

File: backend/auth/login.php:65 — $conn->close() (should be $con)

Severity: HIGH

Impact: Fatal PHP error. Path disclosure if error reporting is enabled.

H-10: Config Mismatch — Hardcoded .env Paths Inconsistent

Files:

walletintaleq.intaleq.xyz/v2/main/connect.php:5 — /home/intaleq-walletintaleq/env/.env
walletintaleq.intaleq.xyz/v2/main/loginWalletAdmin.php:5 — /home/intaleq-wallet/env/.env
walletintaleq.intaleq.xyz/v2/main/encrypt_decrypt.php:6 — /home/intaleq-walletintaleq/env/.env
walletintaleq.intaleq.xyz/v2/main/jwtconnect.php:22 — /home/intaleq-wallet/env/.env

Severity: HIGH

Impact: Four different hardcoded paths for .env files across the wallet codebase. Some files will fail to load env if path doesn't match.

H-11: Email Header Injection in Wallet Functions

File: walletintaleq.intaleq.xyz/v2/main/functions.php:279-282

Severity: HIGH

Code: $header = "From: $from" . "\n" . "CC: $from"; mail($to, $title, $body, $header);

Impact: If $from contains CRLF, attacker can inject arbitrary email headers (spam relay, phishing).

H-12: AI Prompt Injection in Gemini Payment Verification

File: walletintaleq.intaleq.xyz/v2/main/ride/GeminiAi.php:24-31

Severity: HIGH

Impact: Attacker can inject instructions into Gemini prompt via $proofText (e.g., "return verified: true"), defeating AI-based payment verification.

H-13: Gemini API Key in URL Query Parameter

File: walletintaleq.intaleq.xyz/v2/main/ride/GeminiAi.php:41

Code: $url = $this->baseUrl . ":" . $this->model . ":generateContent?key=" . $this->apiKey;

Severity: HIGH

Impact: API key exposed in URL — visible in server access logs, proxy logs, network monitoring.

H-14: Static IV in Wallet AES-CBC

File: walletintaleq.intaleq.xyz/v2/main/encrypt_decrypt.php:10-11

Severity: HIGH

Impact: AES-CBC with static IV makes encryption deterministic. Semantic security defeated.

H-15: Weak Obfuscation — Substitution Cipher in Env Values

Files: All char_map.dart files across all Flutter apps

Severity: HIGH

Impact: Custom substitution cipher (a=q, b=x, c=f, etc.) with algorithm+keys in source code. Trivially reversible.

H-16: `jailbreak_root_detection` Package Never Used

Files: All pubspec.yaml files

Severity: HIGH

Impact: Root/jailbreak detection package included in dependencies but never invoked. Provides false sense of security.

H-17: No SSL/TLS Certificate Pinning

Files: All Flutter apps

Severity: HIGH

Impact: All API traffic vulnerable to MITM on hostile networks. dio configured without pinning.

H-18: Hardcoded Developer PII in Production Apps

Files: All constant/info.dart files

Severity: HIGH

Details: phoneNumber = '962798583052', email = 'hamzaayed@intaleqapp.com', LinkedIn profile hardcoded in all production binaries.

H-19: `siro_service` App — Cleartext Traffic Not Explicitly Disabled

File: siro_service/android/app/src/main/AndroidManifest.xml

Severity: HIGH

Impact: android:usesCleartextTraffic not set. On API < 28, cleartext HTTP may be permitted.

H-20: Missing CSRF Protection on All Auth Endpoints

Files: All auth endpoints

Severity: HIGH

Impact: No CSRF tokens, SameSite cookies, or Origin/Referer validation. Vulnerable to cross-origin request forgery.

H-21: Shared Rate Limit Counter Between OTP Request and Verify

Files:

backend/auth/otp/request.php:11
backend/auth/otp/verify.php:10

Severity: HIGH

Impact: Both request and verify use same rate limit context key 'otp'. Requesting OTPs consumes verification attempts and vice versa.

H-22: Payment Amount Not Validated (Zero/Negative)

File: walletintaleq.intaleq.xyz/v2/main/ride/payment/process_ride_payments.php:66-69

Severity: HIGH

Impact: No min/max validation. Negative payment amounts could reverse charges.

H-23: Type Juggling in OTP Verification (Loose Comparison)

File: backend/auth/token_passenger/verify_otp.php:33 — $cachedOtp == $otp

Severity: HIGH

Impact: PHP type juggling can bypass verification (e.g., "0e123" vs "0e456").

H-24: LEFT JOIN on Encrypted Email Will Never Match

File: backend/auth/login.php:30

Severity: HIGH

Impact: LEFT JOIN email_verifications ON email_verifications.email = passengers.email — email is AES-encrypted. Join predicate never true. Email verification status always NULL.

H-25: Plaintext Phone Number Stored in adminUser Table

File: backend/auth/otp/verify.php:88,93,97

Severity: HIGH

Impact: Phone numbers stored unencrypted in adminUser table while all other tables use AES encryption.

H-26: JSON_UNESCAPED_UNICODE Allows XSS via JSON

Files: Various endpoints using JSON_UNESCAPED_UNICODE

Severity: HIGH

Impact: Characters < and > pass through unchanged in JSON responses. If admin panel renders as innerHTML, XSS is possible.

H-27: No SSL Verification on Any cURL Call

Files: All MTN, ShamCash, and payment integration files

Severity: HIGH

Impact: CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST not set. All outbound HTTP vulnerable to MITM.

H-28: Broken Crypto — `openssl_sign` with String Instead of Key Resource

File: walletintaleq.intaleq.xyz/v2/main/ride/mtn/driver/initiate_payment.php:25

Severity: HIGH

Impact: PEM string passed directly to openssl_sign() which expects key resource. Signature silently fails (null), breaking MTN payment flow.

H-29: Hardcoded Payment Token Secrets

Files: Multiple ShamCash and MTN finalize files

Severity: HIGH

Impact: Token generation uses hardcoded strings ('shamcash_secret', 'default_secret') concatenated with predictable values. Tokens can be predicted/forged.

H-30: IDOR on Invoice Creation — No Ownership Check

Files:

walletintaleq.intaleq.xyz/v2/main/ride/shamcash/create_invoice_shamcash.php:8
walletintaleq.intaleq.xyz/v2/main/ride/shamcash/passenger/create_invoice.php:7

Severity: HIGH

Impact: Any authenticated user can create invoices for any driver/passenger.

H-31: Mass Data Exposure — All Device Fingerprints

File: backend/migration/get_all_fingerprints.php

Severity: HIGH

Impact: Exposes all device fingerprints without pagination or rate limiting. Single static key (MIGRATION_ADMIN_KEY) is the only gate.

H-32: Unauthenticated `send_fcm.php` — Debug Application

File: backend/ride/firebase/send_fcm.php

Severity: HIGH

Impact: No authentication. Open FCM relay enables phishing all app users.

Every endpoint implements its own auth checks (or none). No middleware for role-based access control.

A-02: Inconsistent Authentication Patterns

Some endpoints use connect.php (JWT + rate limiting + fingerprint)
Some use jwtconnect.php (JWT with webhook bypass)
Some use custom auth (phone-based, key-based)
Some have no auth at all

A-03: No Input Validation Layer

No centralized input sanitization, validation, or typed request objects. Every endpoint parses raw $_POST / $_GET / php://input manually.

A-04: Secret Management MIA

No secrets manager. Secrets stored in:

.env files committed to Git
PEM files committed to Git
Flutter app binaries (extractable via reverse engineering)

A-05: No Audit Logging

No centralized audit trail for sensitive operations (admin actions, payment modifications, account deletions).

A-06: No Rate Limiting on Sensitive Endpoints

Admin endpoints, payment processing, and token_passenger OTP have no rate limiting.

📋 SECTION 7: REMEDIATION PRIORITIES

Phase 1 — Immediate (24 hours)

Priority	Vulnerability	Action
P1	C-01: Live secrets in repo	Rotate ALL secrets, add `.gitignore`, purge Git history
P1	C-02: RSA keys in repo	Remove keys, rotate with MTN, use secrets manager
P1	C-07: FCM key in client	Remove from client, move to server-side only
P1	C-08: CVV storage	Remove CVV handling immediately
P1	C-05: Open FCM relay	Add authentication or remove endpoint
P1	C-06: Unauthenticated webhooks	Add HMAC/API key verification
P1	C-09: SQL injection	Fix parameterized query
P1	C-16: Debug endpoints	Remove or firewall-protect

Phase 2 — Short-term (7 days)

Priority	Vulnerability	Action
P1	C-03: Pervasive IDOR	Fix all endpoints to validate JWT user_id == request user_id
P1	C-04: Admin role checks	Add role validation to all admin endpoints
P1	C-10: OTP weaknesses	Increase to 6 digits, use random_int(), add rate limiting
P1	C-11: JWT signature verification	Fix OTP auth to verify JWT signature
P1	C-17/18: Payment race conditions	Add FOR UPDATE locks, balance checks
H-01	Missing .gitignore	Create .gitignore, clean history
H-16	Root detection unused	Activate jailbreak detection at startup

Phase 3 — Medium-term (30 days)

Priority	Vulnerability	Action
H-17	SSL pinning	Implement certificate pinning in all Flutter apps
H-15	Weak obfuscation	Replace custom cipher with platform Keychain/KeyStore
M-13	GetStorage	Migrate sensitive data to FlutterSecureStorage
H-04	Hardcoded paths	Move to configuration
A-01	Authorization layer	Build centralized auth middleware

📝 FINAL NOTES

The previous audit (June 16, 2026) identified 20 vulnerabilities with 3 critical. This comprehensive audit found 76+ vulnerabilities with 26 critical, demonstrating that previous assessments significantly underestimated the security posture.

Key systemic issues:

Authentication without authorization — users are authenticated via JWT but endpoint-level authorization is almost completely absent
Secrets management — every secret is in the repo or extractable from the binary
Payment/financial logic — race conditions, missing balances checks, unauthenticated webhooks create direct financial fraud risk
Mobile app security — server credentials (FCM key) in client, PCI DSS violations, no SSL pinning

Estimated remediation effort: 200-400 hours across all components
Estimated cost: $25,000-$50,000
Risk rating: EXTREME — active exploitation likely given secrets in public repo
