CVE-2025-1465
📋 TL;DR
This vulnerability in lmxcms 1.41 allows remote attackers to inject malicious code through the db.inc.php file in the Maintenance component. The code injection could lead to arbitrary code execution on affected systems. All users running lmxcms 1.41 are potentially affected.
💻 Affected Systems
- lmxcms
📦 What is this software?
Lmxcms by Lmxcms
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with remote code execution leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Limited code execution within the web application context, potentially allowing data manipulation or privilege escalation.
If Mitigated
Attack fails due to input validation, WAF blocking, or lack of necessary permissions for the injected code.
🎯 Exploit Status
Exploit has been publicly disclosed but requires specific conditions and knowledge of the target system.
🛠️ 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
Restrict Maintenance Access
allBlock external access to the Maintenance component using web server configuration or firewall rules.
# Apache: Add to .htaccess or virtual host config
<Location /maintenance>
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>
# Nginx: Add to server block
location /maintenance {
deny all;
allow 127.0.0.1;
}
Input Validation Hardening
allAdd input validation to db.inc.php to sanitize user inputs before processing.
# Add to db.inc.php before vulnerable code
function sanitize_input($input) {
return htmlspecialchars(strip_tags($input), ENT_QUOTES, 'UTF-8');
}
🧯 If You Can't Patch
- Implement strict network segmentation to isolate lmxcms instances from critical systems.
- Deploy a web application firewall (WAF) with rules to detect and block code injection attempts.
🔍 How to Verify
Check if Vulnerable:
Check if lmxcms version is 1.41 and if the db.inc.php file in the Maintenance component exists without input validation.Check Version:
Check the version in lmxcms configuration files or admin panel. Typically in config files or database.Verify Fix Applied:
Verify that Maintenance component is inaccessible from external networks or that input validation has been implemented in db.inc.php.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to maintenance/db.inc.php with suspicious parameters
- PHP error logs showing code execution attempts
Network Indicators:
- HTTP requests containing code injection patterns (e.g., system(), exec(), eval()) targeting maintenance endpoints
SIEM Query:
source="web_server" AND (uri="/maintenance/db.inc.php" OR uri LIKE "%/db.inc.php%") AND (request_body CONTAINS "system(" OR request_body CONTAINS "exec(" OR request_body CONTAINS "eval(")
