CVE-2024-0818
📋 TL;DR
This vulnerability allows attackers to overwrite arbitrary files on systems running vulnerable versions of PaddlePaddle through path traversal. Attackers can exploit improper path validation to write malicious content to sensitive locations. This affects all users of PaddlePaddle before version 2.6.
💻 Affected Systems
- PaddlePaddle
📦 What is this software?
Paddlepaddle by Paddlepaddle
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through overwriting critical system files, installation of persistent backdoors, or destruction of system integrity.
Likely Case
Data corruption, denial of service through overwriting application files, or privilege escalation by modifying configuration files.
If Mitigated
Limited impact with proper file permission restrictions and network segmentation preventing external access.
🎯 Exploit Status
The vulnerability is straightforward to exploit with publicly available details on huntr.com. No authentication required if the vulnerable endpoint is exposed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.6.0 and later
Vendor Advisory: https://github.com/PaddlePaddle/Paddle/security/advisories
Restart Required: Yes
Instructions:
1. Update PaddlePaddle to version 2.6.0 or later using pip: pip install --upgrade paddlepaddle==2.6.0 2. Restart all services and applications using PaddlePaddle. 3. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation to reject any file paths containing directory traversal sequences like '../' or absolute paths.
File Permission Restrictions
linuxRun PaddlePaddle with minimal file system permissions, using chroot or containerization to limit writable directories.
chmod 755 /path/to/paddle/directories
chown non-root-user:non-root-group /path/to/paddle
🧯 If You Can't Patch
- Implement strict network access controls to limit which systems can access PaddlePaddle services
- Deploy application-level firewalls or WAFs with rules to block path traversal patterns
🔍 How to Verify
Check if Vulnerable:
Check PaddlePaddle version: python -c "import paddle; print(paddle.__version__)" - if version is less than 2.6.0, system is vulnerable.
Check Version:
python -c "import paddle; print(paddle.__version__)"
Verify Fix Applied:
After updating, verify version is 2.6.0 or higher using same command and test file operations with traversal attempts.
📡 Detection & Monitoring
Log Indicators:
- Unusual file write operations outside expected directories
- Multiple failed file access attempts with '../' patterns
- File modification timestamps on system files
Network Indicators:
- HTTP requests containing '../' sequences to PaddlePaddle endpoints
- Unusual outbound connections after file write operations
SIEM Query:
source="*paddle*" AND ("../" OR "..\\" OR "/etc/" OR "/root/")
