CVE-2025-2708
📋 TL;DR
This critical vulnerability in zhijiantianya ruoyi-vue-pro 2.4.1 allows remote attackers to perform path traversal attacks via the /admin-api/infra/file/upload endpoint. Attackers can potentially write files to arbitrary locations on the server, leading to unauthorized file access or system compromise. Organizations using this specific version of ruoyi-vue-pro with the vulnerable backend file upload interface are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment by writing malicious files to critical system locations.
Likely Case
Unauthorized file upload to sensitive directories, potentially overwriting configuration files or deploying web shells for persistent access.
If Mitigated
Limited impact with proper file permission restrictions and input validation preventing traversal beyond designated upload directories.
🎯 Exploit Status
Exploit details are publicly available on GitHub. The vulnerability requires access to the admin API endpoint, which typically requires authentication, though authentication bypass could combine with this vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available - vendor did not respond to disclosure
Restart Required: Yes
Instructions:
1. Monitor vendor repositories for security updates. 2. Consider upgrading to newer versions if available. 3. Apply input validation and path sanitization manually if source code access is available.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to reject path parameters containing directory traversal sequences (../, ..\, etc.)
Implement Java filter or interceptor to sanitize 'path' parameter before processing
Access Restriction
allRestrict access to /admin-api/infra/file/upload endpoint using network controls or authentication requirements
Configure web server (nginx/apache) to restrict access to specific IPs or implement additional authentication layers
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block path traversal patterns in requests
- Restrict file system permissions for the application to prevent writing outside designated upload directories
🔍 How to Verify
Check if Vulnerable:
Test by attempting to upload a file with path parameter containing traversal sequences like '../../etc/passwd' to the vulnerable endpointCheck Version:
Check application version in configuration files or via application info endpoints if availableVerify Fix Applied:
Verify that path traversal attempts are rejected with proper error messages and no file operations occur outside designated directories📡 Detection & Monitoring
Log Indicators:
- Multiple failed upload attempts with path traversal patterns
- File operations referencing paths outside expected upload directories
- Unusual file writes to system directories
Network Indicators:
- HTTP requests to /admin-api/infra/file/upload with path parameters containing ../ or similar sequences
- Unusual file upload patterns from single sources
SIEM Query:
source="web_server" AND (uri_path="/admin-api/infra/file/upload" AND (request_parameters CONTAINS "../" OR request_parameters CONTAINS "..\\"))
