Gentoo Linux Security Advisory

Title: MediaWiki: Multiple vulnerabilities (GLSA 200502-33)
Severity: low
Exploitable: remote
Date: February 28, 2005
Bug(s): #80729, #82954
ID: 200502-33

Synopsis

MediaWiki is vulnerable to cross-site scripting, data manipulation and security bypass attacks.

Background

MediaWiki is a collaborative editing software, used by big projects like Wikipedia.

Affected Packages

Package: www-apps/mediawiki
Vulnerable: < 1.3.11
Unaffected: >= 1.3.11
Architectures: All supported architectures


Description

A security audit of the MediaWiki project discovered that MediaWiki is vulnerable to several cross-site scripting and cross-site request forgery attacks, and that the image deletion code does not sufficiently sanitize input parameters.

Impact

By tricking a user to load a carefully crafted URL, a remote attacker could hijack sessions and authentication cookies to inject malicious script code that will be executed in a user's browser session in context of the vulnerable site, or use JavaScript submitted forms to perform restricted actions. Using the image deletion flaw, it is also possible for authenticated administrators to delete arbitrary files via directory traversal.

Workaround

There is no known workaround at this time.

Resolution

All MediaWiki users should upgrade to the latest available version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/mediawiki-1.3.11"
