TikiWiki: Multiple vulnerabilities

Background

TikiWiki is an open source content management system written in PHP.

Description

In numerous files TikiWiki provides an empty sort_mode parameter, causing TikiWiki to display additional information, including database authentication credentials, in certain error messages. TikiWiki also improperly sanitizes the “url” request variable sent to tiki-featured_link.php.

Impact

An attacker could cause a database error in various pages of a TikiWiki instance by providing an empty sort_mode request variable, and gain unauthorized access to credentials of the MySQL databases used by TikiWiki. An attacker could also entice a user to browse to a specially crafted URL that could run scripts in the scope of the user’s browser.

Workaround

There is no known workaround at this time.

Resolution

All TikiWiki users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-1.9.6"
