1. VULNERABILITY DESCRIPTION Potential SQL Injection Flaws were detected Joomla! CMS version 1.5.20. These flaws were reported along with our Cross Scripting Flaw which was fixed in 1.5.21. Developers believed that our reported SQL Injection flaws are not fully exploitable because of Joomla! built-in string filters and were not fixed in 1.5.21 which is currently the latest version. As a result, we disclosed these flaws in order for someone who can exploit these flaws to the next maximum level. 2.
