Technical details
The Gridbox extension for Joomla (com_gridbox) fails to implement sufficient anti-CSRF tokens (nonce validation) across various endpoints in its administrative interface. An attacker can exploit this by crafting malicious web pages that, when visited by an authenticated administrator, trigger unintended state-changing requests to the Joomla backend. These vectors allow for various administrative actions to be performed on behalf of the victim. The vulnerabilities were identified during a comprehensive security audit by mySites.guru and are addressed in version 2.20.2.
