Description Jan Lieskovsky 2011-09-08 13:13:58 UTC

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.

This issue did NOT affect the versions of the zikula package, as shipped with Fedora release of 14 and 15 (these versions do not contain the affected code in question yet).

Comment 4 Jan Lieskovsky 2011-10-04 12:07:46 UTC

A potentially duplicate CVE identifier of CVE-2011-3979 has been also assigned to this issue. Checking with Mitre:
[5] http://www.openwall.com/lists/oss-security/2011/10/04/3

which CVE identifier is the proper one to be used to reference to this issue. Will update this bug later yet, if / once necessary.
