DESCRIPTION OF THE VULNERABILITY

Three vulnerabilities were announced in Joomla.

The HTTP_REFERER variable, which contains the Referer header, is not correctly filtered. An attacker can therefore generate a Cross Site Scripting. [grav:2/4; 20090604]

The PHP_SELF variable, which contains a fragment of the requested url, is not correctly filtered. An attacker can therefore generate a Cross Site Scripting. [grav:2/4; 20090605]

Some PHP scripts do not use _JEXEC to limit their access. An attacker can therefore read their contents, in order to obtain information on internal paths. [grav:2/4; 20090606]
