🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd proper anti-CSRF tokens to all state-changing requests
Application-specific implementation required
Require POST for State-Changing Actions
allModify application to reject GET requests for sensitive operations
Application configuration/development required
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block suspicious GET requests to the BackOffice interface
- Enforce strict same-origin policies and implement additional authentication steps for sensitive operations
🔍 How to Verify
Check if Vulnerable:
Test if state-changing operations can be performed via GET requests without proper CSRF tokens. Check application version against affected version.Check Version:
Check application interface or configuration files for version information. Specific command depends on deployment.Verify Fix Applied:
Verify that all state-changing operations require POST requests with valid CSRF tokens. Test with the bypass techniques described in the reference PDF.📡 Detection & Monitoring
