Subject: CVE Request -- Zikula (v1.3.x) -- XSS flaw due improper sanitization
of 'themename' parameter by setting default, modifying and deleting themes
Hello Josh, Steve, vendors,
it was found that the Zikula web application framework did not
properly sanitize the 'themename' parameter, while setting particular
theme as a default one, modifying the theme or deleting it. A remote
attacker, with Zikula administrator privilege, could use this flaw to
execute arbitrary HTML or web script code in the context of the
affected website.
