CVE-2024-10749
📋 TL;DR
This critical vulnerability in ThinkAdmin allows remote attackers to execute arbitrary code through insecure deserialization in the Plugs.php file. It affects ThinkAdmin versions up to 6.1.67, potentially compromising entire systems if exploited successfully.
💻 Affected Systems
- ThinkAdmin
📦 What is this software?
Thinkadmin by Thinkadmin
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Unauthorized access to the ThinkAdmin application with potential for privilege escalation and data manipulation.
If Mitigated
Limited impact with proper network segmentation, input validation, and deserialization controls in place.
🎯 Exploit Status
Exploit has been publicly disclosed and may be used, though complexity is high according to vulnerability description.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to version 6.1.68 or later if released, or apply workarounds.
🔧 Temporary Workarounds
Disable vulnerable endpoint
allBlock access to the vulnerable Plugs.php file to prevent exploitation
# Add to web server configuration (Apache example)
<Location "/app/admin/controller/api/Plugs.php">
Deny from all
</Location>
# Nginx example
location /app/admin/controller/api/Plugs.php {
deny all;
}
Input validation filter
allAdd validation to reject malicious uptoken parameter values
# In Plugs.php, add validation before deserialization
if (!preg_match('/^[a-zA-Z0-9\-_]+$/', $uptoken)) {
die('Invalid token');
}
🧯 If You Can't Patch
- Implement strict network segmentation to isolate ThinkAdmin instances
- Deploy web application firewall with deserialization attack detection rules
🔍 How to Verify
Check if Vulnerable:
Check ThinkAdmin version and verify if Plugs.php file exists with vulnerable deserialization codeCheck Version:
# Check ThinkAdmin version in configuration files or admin panelVerify Fix Applied:
Verify Plugs.php has been modified with proper input validation or endpoint is blocked📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /app/admin/controller/api/Plugs.php
- Deserialization errors in application logs
- Suspicious PHP execution patterns
Network Indicators:
- HTTP requests with crafted uptoken parameters
- Traffic to Plugs.php endpoint from unexpected sources
SIEM Query:
source="web_logs" AND uri="/app/admin/controller/api/Plugs.php" AND (method="POST" OR params CONTAINS "uptoken")
