CVE-2025-24967
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in reNgine's admin panel allows attackers to inject malicious scripts into username fields during user creation. When administrators view or interact with compromised user entries, these scripts execute, potentially compromising sensitive admin functionalities. This affects all reNgine installations up to version 2.20.

⚠️ Risk & Real-World Impact
Worst Case
Complete admin account takeover leading to full system compromise, data exfiltration, or deployment of additional malware.
Likely Case
Session hijacking, credential theft, or unauthorized access to admin panel functions.
If Mitigated
Limited to script execution in admin context with proper input validation bypassed.
🎯 Exploit Status
Requires attacker access to create users (typically authenticated), but exploitation is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://github.com/yogeshojha/rengine/security/advisories/GHSA-23wx-5q5w-334w
Restart Required: No
Instructions:
Monitor the reNgine GitHub repository for security updates beyond version 2.20. Apply patches immediately when available.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement server-side input validation and sanitization for username fields to strip or escape HTML/JavaScript content.
Content Security Policy
allImplement strict Content Security Policy headers to prevent script execution from untrusted sources.
🧯 If You Can't Patch
- Restrict admin panel access to trusted IP addresses only using firewall rules.
- Implement web application firewall (WAF) rules to block XSS payloads in username fields.
🔍 How to Verify
Check if Vulnerable:
Check if reNgine version is 2.20 or earlier. Attempt to create a user with a username containing basic XSS payload like <script>alert('test')</script> and see if it executes when viewed.Check Version:
Check the reNgine web interface or configuration files for version information.Verify Fix Applied:
After updating to a patched version, repeat the XSS test with malicious username payloads to confirm they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual username creation attempts with script tags or JavaScript code
- Admin panel access logs showing suspicious user interactions
Network Indicators:
- HTTP requests containing script tags in username parameters
- Unusual outbound connections from admin panel
