⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers gain administrative privileges, modify all permissions, and potentially access sensitive data or disrupt operations.
Likely Case
Unauthorized privilege escalation allowing attackers to modify user permissions, potentially gaining access to restricted functionality or data.
If Mitigated
Limited impact with proper network segmentation and authentication controls, potentially only affecting non-critical systems.
🎯 Exploit Status
The exploit is public and may be used. Attack requires some level of access but not necessarily authentication to the permission management functions.

🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to the permission management endpoints to authorized IPs only
# Use firewall rules to restrict access to /permission endpoints
# Example: iptables -A INPUT -p tcp --dport [APP_PORT] -s [TRUSTED_IPS] -j ACCEPT
Authentication Enforcement
allEnsure all permission management endpoints require proper authentication
# Review and enforce authentication middleware on all /permission routes
# Check that @PreAuthorize or similar annotations are properly configured
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the warehouse application from untrusted networks
- Deploy a web application firewall (WAF) with rules to detect and block permission manipulation attempts
🔍 How to Verify
Check if Vulnerable:
Check if your yeqifu warehouse commit hash is aaf29962ba407d22d991781de28796ee7b4670e4 or earlier. Review PermissionController.java for missing authorization checks on addPermission/updatePermission/deletePermission methods.Check Version:
git log --oneline -1Verify Fix Applied:
Verify that proper authorization checks (e.g., @PreAuthorize annotations) are implemented on all permission management endpoints in PermissionController.java📡 Detection & Monitoring
Log Indicators:
- Unusual permission modification events
- Multiple failed authorization attempts followed by successful permission changes
- Requests to /permission endpoints from unexpected sources
Network Indicators:
- Unusual traffic patterns to permission management endpoints
- POST/PUT/DELETE requests to /permission without proper authentication headers
