CVE-2025-0401
📋 TL;DR
This critical path traversal vulnerability in the Reggie 1.0 application allows attackers to access arbitrary files on the server by manipulating the 'name' parameter in the download function. Remote attackers can exploit this to read sensitive system files. All systems running the vulnerable version are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through reading sensitive configuration files, credentials, or system files leading to further exploitation.
Likely Case
Unauthorized access to sensitive application files, configuration data, or user information stored on the server.
If Mitigated
Limited impact with proper file system permissions and input validation in place.
🎯 Exploit Status
Exploit disclosed in GitHub issues. Simple path traversal attack requiring minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Check GitHub repository for patches. 2. Apply input validation to sanitize 'name' parameter. 3. Implement proper path normalization. 4. Restart application after changes.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject path traversal sequences in the name parameter
Implement validation in CommonController.java to check for '../' and similar sequences
Web Application Firewall Rule
allBlock requests containing path traversal patterns
WAF rule to block requests with '../', '..\', or similar path traversal patterns
🧯 If You Can't Patch
- Implement network segmentation to isolate vulnerable systems
- Deploy web application firewall with path traversal detection rules
🔍 How to Verify
Check if Vulnerable:
Test by sending requests with '../' sequences in the name parameter to the download endpoint
Check Version:
Check application version in pom.xml or build configuration
Verify Fix Applied:
Verify that path traversal attempts return error responses instead of file contents
📡 Detection & Monitoring
Log Indicators:
- HTTP requests with '../' sequences in parameters
- Unusual file access patterns from download endpoint
Network Indicators:
- Multiple requests with path traversal patterns to CommonController endpoints
