What to do

AI-suggested

1. Immediate mitigation should include restricting access to the /modules/School Admin/messengerSettings.php endpoint via network controls such as firewalls or web application firewalls (WAFs) to limit exposure. 2. Implement input validation and sanitization at the application layer to ensure that any data passed to the Twig template engine is properly escaped or filtered. 3. Monitor application logs for unusual requests targeting the messengerSettings.php script or attempts to inject template syntax. 4. If possible, disable or isolate the vulnerable module until an official patch is released by the Gibbon development team. 5. Employ runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions to detect and block suspicious code execution attempts. 6. Keep the Gibbon platform and all dependencies up to date and subscribe to vendor security advisories for timely patch deployment. 7. Conduct a thorough security review of all template rendering code to identify and remediate similar injection risks. 8. Educate administrators and developers on secure template handling practices to prevent future SSTI vulnerabilities.

Description

Gibbon through 26.0.00 allows /modules/School%20Admin/messengerSettings.php Server Side Template Injection leading to Remote Code Execution because input is passed to the Twig template engine (messengerSettings.php) without sanitization.
