CVE-2025-15394
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on iCMS systems through code injection in the configuration parameter handler. Attackers can exploit this by manipulating POST parameters to inject malicious code that gets executed on the server. All iCMS installations up to version 8.0.0 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, steal data, install backdoors, or pivot to other systems.
Likely Case
Unauthorized code execution leading to website defacement, data theft, or installation of cryptocurrency miners.
If Mitigated
Limited impact if proper input validation and WAF rules are in place, potentially resulting in failed exploitation attempts.
🎯 Exploit Status
Exploit details are publicly available. Attack requires access to the admin configuration interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Enhancement
allAdd strict input validation to the Save function in ConfigAdmincp.php to sanitize config parameters
Edit app/config/ConfigAdmincp.php and implement parameter sanitization before processing
Access Restriction
allRestrict access to the admin configuration interface using IP whitelisting or additional authentication
Configure web server (Apache/Nginx) to restrict access to admin paths
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block suspicious POST requests to admin configuration endpoints
- Monitor and audit all access to the admin configuration interface for unusual activity
🔍 How to Verify
Check if Vulnerable:
Check if iCMS version is 8.0.0 or earlier by examining version files or admin interfaceCheck Version:
Check iCMS version in admin panel or version.txt fileVerify Fix Applied:
Test if code injection attempts are properly blocked in the configuration save functionality📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to ConfigAdmincp.php with suspicious parameter values
- Multiple failed authentication attempts to admin interface
Network Indicators:
- POST requests containing code injection patterns to admin configuration endpoints
