CVE-2025-45529
📋 TL;DR
This vulnerability allows unauthenticated attackers to read arbitrary files on SSCMS servers by sending specially crafted GET requests to the /cms/templates/templatesAssetsEditor endpoint. It affects SSCMS v7.3.1 installations, potentially exposing sensitive configuration files, credentials, or other system data.
💻 Affected Systems
- SSCMS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive files like configuration files containing database credentials, API keys, or system files, leading to complete system compromise.
Likely Case
Attackers will read configuration files to extract credentials and potentially gain further access to the system or database.
If Mitigated
With proper network segmentation and access controls, impact is limited to file disclosure without lateral movement.
🎯 Exploit Status
Exploitation requires only a crafted HTTP GET request with directory traversal payloads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Block vulnerable endpoint
allRestrict access to /cms/templates/templatesAssetsEditor via web server configuration or firewall rules.
# Apache: RewriteRule ^/cms/templates/templatesAssetsEditor - [F]
# Nginx: location ~ ^/cms/templates/templatesAssetsEditor { deny all; }
Input validation filter
allImplement WAF rules to block directory traversal patterns in requests to the vulnerable endpoint.
# Example ModSecurity rule: SecRule REQUEST_URI "@contains ../" "id:1001,phase:1,deny"
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the SSCMS instance
- Monitor logs for suspicious file read attempts and implement file integrity monitoring
🔍 How to Verify
Check if Vulnerable:
Send a GET request to /cms/templates/templatesAssetsEditor with a directory traversal payload and check if sensitive files are returned.Check Version:
Check SSCMS version in admin panel or configuration filesVerify Fix Applied:
Test the same exploit attempt after implementing workarounds to confirm access is blocked.📡 Detection & Monitoring
Log Indicators:
- HTTP GET requests to /cms/templates/templatesAssetsEditor containing ../ patterns
- Unusual file access patterns from web server process
Network Indicators:
- HTTP requests with directory traversal sequences in URL parameters
SIEM Query:
source="web_server" AND url="/cms/templates/templatesAssetsEditor" AND (url="*../*" OR parameters="*../*")
