Synopsis

Multiple vulnerabilities have been discovered in TikiWiki, some of them having unknown impact.

2. Impact Information

Background

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

Description

Jesus Olmos Gonzalez from isecauditors reported insufficient sanitization of the "movies" parameter in file tiki-listmovies.php (CVE-2007-6528).
Mesut Timur from H-Labs discovered that the input passed to the "area_name" parameter in file tiki-special_chars.php is not properly sanitised before being returned to the user (CVE-2007-6526).
redflo reported multiple unspecified vulnerabilities in files tiki-edit_css.php, tiki-list_games.php, and tiki-g-admin_shared_source.php (CVE-2007-6529).

Impact

A remote attacker can craft the "movies" parameter to run a directory traversal attack through a ".." sequence and read the first 1000 bytes of any arbitrary file, or conduct a cross-site scripting (XSS) attack through the "area_name" parameter. This attack can be exploited to execute arbitrary HTML and script code in a user's browser session, allowing for the theft of browser session data or cookies in the context of the affected web site. The impacts of the unspecified vulnerabilities are still unknown.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution
