CVE-2024-24161
📋 TL;DR
MRCMS 3.0 contains an arbitrary file read vulnerability in the /admin/file/edit.do endpoint where the path parameter is not properly filtered. This allows authenticated attackers to read sensitive files from the server filesystem. Organizations running MRCMS 3.0 with the admin interface exposed are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive configuration files, database credentials, SSH keys, or other critical system files, potentially leading to full system compromise.
Likely Case
Attackers with admin access could read application configuration files containing database credentials or other sensitive information.
If Mitigated
With proper network segmentation and access controls, impact would be limited to the web application directory only.
🎯 Exploit Status
Exploitation requires admin credentials but is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to restrict path parameter to allowed directories only
Implement path traversal filters in /admin/file/edit.do endpoint
Web Application Firewall Rule
allBlock requests containing directory traversal sequences to the vulnerable endpoint
WAF rule: Block requests to /admin/file/edit.do containing '../' or similar traversal patterns
🧯 If You Can't Patch
- Restrict network access to admin interface using firewall rules
- Implement strict access controls and monitor admin user activities
🔍 How to Verify
Check if Vulnerable:
Test authenticated access to /admin/file/edit.do with path traversal payloads like '../../etc/passwd'Check Version:
Check MRCMS version in admin panel or configuration filesVerify Fix Applied:
Verify that path traversal attempts return error messages instead of file contents📡 Detection & Monitoring
Log Indicators:
- Multiple failed file read attempts
- Requests to /admin/file/edit.do with unusual path parameters
Network Indicators:
- HTTP requests containing directory traversal sequences to admin endpoints
SIEM Query:
web.url:*file/edit.do AND (web.uri:*../* OR web.uri:*..\*)
