Subject: [PATCH] - Replace hardcoded cryptographic key with generated
per-installation key - Upgrade password generation from mt_rand() to
cryptographically secure random functions - Fix weak password hashing
(MD5+SHA1) by implementing password_hash() with backward compatibility -
Prevent SQL injection in CopyAdminTable() with table name whitelist
validation - Enable SSL verification in email sending functions - Remove
debug function that could leak sensitive information - Improve token
generation security
Hardcoded Cryptographic Key (CWE-321):
Fix Applied:
-Added get_crypto_key() function that generates unique keys per installation
-Keys are generated using random_bytes() or openssl_random_pseudo_bytes()
-Fallback mechanism with warnings for older PHP versions
-Keys can be stored in configuration files outside web root
Impact: Prevents universal compromise where attackers with one installation's data can compromise ALL installations.
Weak Password Hashing (CWE-327):
Fix Applied:
-Added deprecation warning for old passwordhash() function
I-mplemented password_hash() with PASSWORD_DEFAULT (bcrypt/Argon2)
-Maintains backward compatibility for existing hashes
-Added proper password verification with password_verify()
Impact: Passwords are now properly hashed using modern algorithms, resistant to brute force attacks.
Insecure Random Generation (CWE-338):
Fix Applied:
-Replaced mt_rand() with random_int() (PHP 7.0+)
-Fallback to openssl_random_pseudo_bytes() for older PHP
-Only uses mt_rand() as last resort with security warnings
-Applied to password generation, salt creation, and token generation
Impact: Random values (passwords, salts, tokens) are now cryptographically secure and unpredictable.
#Added table name validation in CopyAdminTable()
-Enabled SSL verification - Fixed email sending security
-Removed debug function - Eliminated information leakage risk
