Technical details
An improper access control vulnerability (CWE-284) exists in the 'resetPassword' method of the Balbooa Gridbox extension for Joomla. The flaw allows an unauthenticated remote attacker to reset the password for any user account, with the exception of super administrators. This is achieved by directly invoking the method without proper session or token validation. Once the password is reset, the attacker can log in as the target user. This vulnerability is part of a suite of 23 critical flaws discovered in the component, some of which are reportedly being exploited in the wild. Users should update to version 2.20.2 immediately to remediate this and other associated risks.
