# Contrast Security RASP Policy for CVE-2025-12480 Mitigation # Navigate to: Policies -> Add New Policy 1. **Policy Name:** Block Triofox Auth Bypass (CVE-2025-12480) 2. **Select Application:** Choose the Triofox application from the list. 3. **Mode:** Set to 'Block'. 4. **Configure Rules:** * Enable the 'Authentication' rule category. * Add a custom rule for 'Path Traversal' and apply it to the Triofox application's known file access directories. * Create a 'Virtual Patch' rule targeting the specific method or class responsible for the authentication check in Triofox (if known). Set the action to 'Log & Block' any attempts to call downstream functions without this check being satisfied. 5. **Save and Apply Policy.** 6. **Verification:** Monitor the 'Attacks' dashboard for any blocked events related to this policy, confirming the agent is correctly identifying and stopping exploit attempts.
