Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2013-4301)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

includes/resourceloader/ResourceLoaderContext.php in MediaWiki 1.19.x before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 allows remote attackers to obtain sensitive information via a "<" (open angle bracket) character in the lang parameter to w/load.php, which reveals the installation path in an error message.


2) Cross-site request forgery (CVE-ID: CVE-2013-4302)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and wiki/api.


3) Cross-site scripting (CVE-ID: CVE-2013-4305)

Vulnerability allows a remote attacker to perform XSS attacks.

The vulnerability is caused by an input validation error in contrib/example.php in the SyntaxHighlight GeSHi extension for MediaWiki, possibly as downloaded before September 2013, when processing PATH_INFO. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
