Technical details
A payment bypass vulnerability exists in the Balbooa Gridbox extension for Joomla (com_gridbox) in versions prior to 2.20.2. The flaw resides in the handling of payment processing logic, where insufficient validation allows a remote, unauthenticated attacker to bypass the payment step of a transaction. This is part of a larger set of 23 vulnerabilities discovered in the component, which stem from a systemic failure to validate request parameters. An attacker can exploit this to obtain goods or services without authorization. The issue is resolved in version 2.20.2.
