Contenido "checkParams()" Cross-Site Scripting Vulnerability

Description

A vulnerability has been discovered in Contenido, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "idart", "lang", or "idcat" GET parameters to cms/front_content.php is not properly sanitised before being returned to the user within the "checkParams()" function (contenido/classes/class.requestvalidator.php). This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that Advanced Mod Rewrite (AMR) is disabled (disabled by default).
The vulnerability is confirmed in version 4.9.5 and reported in versions 4.9.x through 4.9.4.
