CVE-2024-1603
📋 TL;DR
CVE-2024-1603 is a path traversal vulnerability in PaddlePaddle's read_file function that allows attackers to read arbitrary files from the server filesystem. This affects applications using PaddlePaddle 2.6.0 that process user-controlled file paths. The vulnerability enables unauthorized access to sensitive system files.
💻 Affected Systems
- PaddlePaddle
📦 What is this software?
Paddlepaddle by Paddlepaddle
⚠️ Risk & Real-World Impact
Worst Case
Attackers can read sensitive files like /etc/passwd, SSH keys, configuration files, and database credentials, potentially leading to complete system compromise.
Likely Case
Unauthorized reading of application configuration files, source code, or user data stored on the server.
If Mitigated
Limited to reading files accessible by the application's service account, with no ability to write or execute files.
🎯 Exploit Status
Simple path traversal payloads can exploit this vulnerability without authentication if user input reaches the vulnerable function.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.6.1 or later
Vendor Advisory: https://github.com/PaddlePaddle/Paddle/security/advisories
Restart Required: No
Instructions:
1. Update PaddlePaddle to version 2.6.1 or later using pip: pip install --upgrade paddlepaddle 2. Review and update any custom code using read_file to validate user input.
🔧 Temporary Workarounds
Input Validation
allImplement strict input validation to prevent path traversal in user-controlled file paths
Function Restriction
allReplace paddle.vision.ops.read_file with custom functions that validate file paths
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user-controlled file paths
- Restrict application permissions using least privilege principles and containerization
🔍 How to Verify
Check if Vulnerable:
Check if using PaddlePaddle 2.6.0 and if application uses paddle.vision.ops.read_file with user inputCheck Version:
python -c "import paddle; print(paddle.__version__)"Verify Fix Applied:
Verify PaddlePaddle version is 2.6.1 or later and test file path validation📡 Detection & Monitoring
