CVE-2025-67504
📋 TL;DR
WBCE CMS versions 1.6.4 and below use PHP's non-cryptographically secure rand() function to generate passwords, making them predictable. Attackers can brute-force or predict passwords for new accounts or password resets, potentially leading to account compromise or privilege escalation. All users running affected versions are vulnerable.
💻 Affected Systems
- WBCE CMS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full administrative takeover of the CMS, data exfiltration, website defacement, or ransomware deployment.
Likely Case
Compromise of user accounts created during the vulnerable period, leading to unauthorized content modifications or data access.
If Mitigated
Limited impact if strong password policies, multi-factor authentication, and monitoring are in place.
🎯 Exploit Status
Exploitation requires access to password generation or reset functionality, but the cryptographic weakness makes brute-forcing trivial.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.6.5
Vendor Advisory: https://github.com/WBCE/WBCE_CMS/security/advisories/GHSA-76gj-pmvx-jcc6
Restart Required: No
Instructions:
1. Backup your WBCE CMS installation and database. 2. Download version 1.6.5 from the official GitHub releases. 3. Replace all files with the new version, preserving configuration files. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Disable automatic password generation
allManually set strong passwords for all new accounts and password resets instead of using the vulnerable function.
🧯 If You Can't Patch
- Force password resets for all accounts created or reset during the vulnerable period.
- Implement strict monitoring for suspicious account activity and enable multi-factor authentication.
🔍 How to Verify
Check if Vulnerable:
Check the WBCE CMS version in the admin panel or by examining the /framework/CHANGELOG.md file.Check Version:
grep -i 'version' /path/to/wbce/framework/CHANGELOG.md | head -1Verify Fix Applied:
Confirm the version is 1.6.5 or higher and check that the GenerateRandomPassword() function in /framework/functions.php uses random_int() instead of rand().📡 Detection & Monitoring
Log Indicators:
- Unusual account creation spikes
- Multiple failed login attempts from new accounts
- Password reset requests for administrative accounts
