CVE-2023-31502
📋 TL;DR
Altenergy Power Control Software C1.2.5 contains a remote code execution vulnerability in the /models/management_model.php component due to insufficient verification of data authenticity (CWE-345). This allows attackers to execute arbitrary code on affected systems, potentially compromising power control infrastructure. Organizations using Altenergy Power Control Software C1.2.5 are affected.
💻 Affected Systems
- Altenergy Power Control Software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, disrupt power control operations, pivot to other systems, and potentially cause physical damage to connected power equipment.
Likely Case
Unauthorized access to power control systems, data theft, manipulation of power settings, and installation of persistent backdoors.
If Mitigated
Limited impact with proper network segmentation, strict access controls, and monitoring in place, potentially only affecting isolated systems.
🎯 Exploit Status
The vulnerability is in a web-accessible component with public disclosure including technical details. Attackers can exploit this without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check vendor website for security updates
2. Apply any available patches
3. Verify the fix by testing the vulnerable endpoint
4. Monitor for vendor communications about this CVE
🔧 Temporary Workarounds
Block access to vulnerable endpoint
linuxRestrict access to /models/management_model.php using web server configuration or firewall rules
# Apache: Add to .htaccess or virtual host config
<Files "management_model.php">
Order deny,allow
Deny from all
</Files>
# Nginx: Add to server block
location ~ /models/management_model\.php$ {
deny all;
return 403;
}
Network segmentation
linuxIsolate Altenergy systems from untrusted networks and restrict access to management interfaces
# Example iptables rule to restrict access
# iptables -A INPUT -p tcp --dport [WEB_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
# iptables -A INPUT -p tcp --dport [WEB_PORT] -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the Altenergy web interface
- Deploy a web application firewall (WAF) with rules to block exploitation attempts targeting this vulnerability
🔍 How to Verify
Check if Vulnerable:
Check if /models/management_model.php is accessible via HTTP/HTTPS and if the software version is C1.2.5. Test with a harmless payload to confirm vulnerability.Check Version:
# Check software version in web interface or configuration files
# Typically found in web interface or /var/www/html/ configurationVerify Fix Applied:
Verify that access to /models/management_model.php is properly restricted and test with exploitation attempts that should be blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual requests to /models/management_model.php
- Suspicious POST parameters in web logs
- Unexpected system command execution
- Failed authentication attempts followed by exploitation
Network Indicators:
- HTTP requests to /models/management_model.php with unusual parameters
- Outbound connections from Altenergy systems to suspicious IPs
- Unusual traffic patterns to power control management interfaces
SIEM Query:
source="web_logs" AND (url="/models/management_model.php" OR url="*management_model*") AND (method="POST" OR params="*cmd*" OR params="*exec*" OR params="*system*")
