⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through arbitrary file read/write/delete, potentially leading to sensitive data exposure, system takeover, or ransomware deployment.
Likely Case
Unauthorized file access leading to information disclosure, configuration file tampering, or denial of service through critical file deletion.
If Mitigated
Limited impact with proper file permission restrictions and input validation in place.
🎯 Exploit Status
Proof of concept is publicly available on GitHub. The vulnerability is straightforward to exploit with basic path traversal techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available - vendor did not respond to disclosure
Restart Required: No
Instructions:
No official patch available. Consider migrating to a maintained fork or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation to reject filenames containing path traversal sequences
Implement filename validation in ImageUploadService.java to reject ../, ..\, and similar sequences
File Path Canonicalization
allUse canonical paths and ensure uploaded files stay within designated directories
Use Path.normalize() and Path.toAbsolutePath() in Java to prevent directory traversal
🧯 If You Can't Patch
- Implement WAF rules to block requests containing path traversal patterns in filename parameters
- Restrict file system permissions for the application to limit potential damage scope
🔍 How to Verify
Check if Vulnerable:
Check if your Spring-Boot-In-Action version includes commit 807fd37643aa774b94fd004cc3adbd29ca17e9aa or earlier. Review ImageUploadService.java for filename parameter handling.Check Version:
git log --oneline | grep -i 'spring-boot-in-action' or check project commit historyVerify Fix Applied:
Test file upload functionality with malicious filenames containing ../ sequences to ensure they are rejected.📡 Detection & Monitoring
Log Indicators:
- Multiple failed file upload attempts with suspicious filenames
- Access to files outside expected upload directories
- Error logs showing path traversal attempts
Network Indicators:
- HTTP requests with ../ or ..\ in filename parameters
- Unusual file access patterns from single IPs
SIEM Query:
source="web_logs" AND (filename="*../*" OR filename="*..\\*") AND status=200
