CVE Request -- Zikula (v1.3.x) -- XSS flaw due improper sanitization of 'themename' parameter by setting default, modifying and deleting themes

[Jan Lieskovsky <jlieskov () redhat com>]

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.
