CVE-2025-49141
📋 TL;DR
CVE-2025-49141 is an OS command injection vulnerability in HAX CMS PHP's gitImportSite functionality. Authenticated attackers can execute arbitrary commands on the backend server by crafting malicious URLs that bypass input validation. This affects all HAX CMS PHP installations prior to version 11.0.3.
💻 Affected Systems
- HAX CMS PHP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full server compromise allowing data exfiltration, lateral movement, ransomware deployment, or complete system takeover.
Likely Case
Unauthorized data access, privilege escalation, backdoor installation, or service disruption.
If Mitigated
Limited impact due to network segmentation, minimal user privileges, and proper input validation.
🎯 Exploit Status
Exploitation requires authenticated access but uses simple command injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 11.0.3
Vendor Advisory: https://github.com/haxtheweb/issues/security/advisories/GHSA-g4cf-pp4x-hqgw
Restart Required: No
Instructions:
1. Update HAX CMS PHP to version 11.0.3 or later. 2. Verify the patch is applied by checking the gitImportSite functionality. 3. Test the fix with safe input validation.
🔧 Temporary Workarounds
Disable gitImportSite functionality
allTemporarily disable the vulnerable gitImportSite endpoint until patching is complete.
# Modify your HAX CMS configuration to disable gitImportSite
# Or use web server rules to block access to the endpoint
Implement input validation proxy
allAdd additional input validation layer before requests reach the vulnerable function.
# Add custom validation in your application middleware
# Example: Validate URL format and reject suspicious patterns
🧯 If You Can't Patch
- Restrict access to authenticated users with minimal privileges only.
- Implement network segmentation to isolate HAX CMS from critical systems.
🔍 How to Verify
Check if Vulnerable:
Check if your HAX CMS PHP version is below 11.0.3 and if gitImportSite functionality is accessible.Check Version:
Check HAX CMS PHP version in admin panel or configuration files.Verify Fix Applied:
Confirm version is 11.0.3 or higher and test gitImportSite with safe input to ensure proper validation.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to gitImportSite endpoint
- Suspicious command strings in server logs
- Multiple failed validation attempts
Network Indicators:
- Unexpected outbound connections from HAX CMS server
- Command output being sent via HTTP requests
SIEM Query:
search 'POST /gitImportSite' AND (suspicious_command OR validation_bypass)
