#2010-002 Joomla input sanitization errors (XSS)


Joomla, an open source content management system, suffers from a cross-site
scripting (XSS) vulnerability.

Insufficient input sanitization on the parameters passed to pages related to
administration settings leads to arbitrary javascript injection in the context
of the user session, this could be potentially exploited to hijack the session
of the Joomla administrator.

Affected version:

Joomla <= 1.5.19

Fixed version:

Joomla >= 1.5.20
