CVE-2025-63888
📋 TL;DR
A remote code execution vulnerability exists in ThinkPHP 5.0.24's template file driver. Attackers can exploit the read function in File.php to execute arbitrary code on affected systems. This affects all deployments running ThinkPHP 5.0.24 with the vulnerable component.
💻 Affected Systems
- ThinkPHP
📦 What is this software?
Thinkphp by Thinkphp
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to execute arbitrary commands, steal data, install malware, pivot to other systems, and maintain persistent access.
Likely Case
Webshell deployment leading to data exfiltration, credential theft, and lateral movement within the network.
If Mitigated
Limited impact with proper WAF rules, network segmentation, and minimal privileges preventing lateral movement.
🎯 Exploit Status
Public exploit code exists in GitHub gists. Exploitation requires network access to vulnerable endpoint but no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.0.25 or later
Vendor Advisory: https://www.thinkphp.cn/
Restart Required: No
Instructions:
1. Backup current installation. 2. Update ThinkPHP to version 5.0.25 or higher. 3. Verify the File.php file has been updated. 4. Test application functionality.
🔧 Temporary Workarounds
Disable File Template Driver
allTemporarily disable the vulnerable File template driver if not required
Modify configuration to use alternative template driver
WAF Rule Implementation
allBlock malicious requests targeting the vulnerable endpoint
Add WAF rule to block requests containing think\template\driver\File.php patterns
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems
- Deploy application-level firewall rules to block exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check if thinkphp/library/think/template/driver/File.php exists and contains vulnerable read function in version 5.0.24Check Version:
Check composer.json or framework version file for '5.0.24'Verify Fix Applied:
Verify ThinkPHP version is 5.0.25+ and File.php has been updated📡 Detection & Monitoring
Log Indicators:
- Unusual POST/GET requests to template endpoints
- File inclusion attempts in access logs
- Unexpected process execution from web server
Network Indicators:
- HTTP requests containing think/template/driver/File.php patterns
- Outbound connections from web server to unknown IPs
