Technical details
Multiple SQL injection (SQLi) vulnerabilities exist in the Balbooa Gridbox extension for Joomla (com_gridbox) prior to version 2.20.2. These flaws reside in several endpoints that fail to properly neutralize special elements in SQL commands (CWE-89). An unauthenticated remote attacker can exploit these vectors by sending specially crafted HTTP requests to the affected site. Successful exploitation allows for the extraction of sensitive data from the database, including Joomla user tables and password hashes. This vulnerability was part of a larger set of 23 critical flaws identified in the component, some of which are reportedly being exploited in the wild. Users should update to version 2.20.2 immediately.
