PHP remote file inclusion vulnerability in MediaWikiParserTest.php in MediaWiki 1.16 beta, when register_globals is enabled, allows remote attackers to execute arbitrary PHP code via unspecified vectors.
Multiple directory traversal vulnerabilities in (1) languages/Language.php and (2) includes/StubObject.php in MediaWiki 1.8.0 and other versions before 1.16.2, when running on Windows and possibly Novell Netware, allow remote attackers to include and execute arbitrary local PHP files via vectors related to a crafted language file and the Language::factory function.
Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.2 allows remote attackers to inject arbitrary web script or HTML via crafted Cascading Style Sheets (CSS) comments, aka "CSS injection vulnerability."
MediaWiki before 1.16.1, when user or site JavaScript or CSS is enabled, allows remote attackers to conduct clickjacking attacks via unspecified vectors.
Cross-site scripting (XSS) vulnerability in MediaWiki 1.15 before 1.15.4 and 1.16 before 1.16 beta 3 allows remote attackers to inject arbitrary web script or HTML via crafted Cascading Style Sheets (CSS) strings that are processed as script by Internet Explorer.
Cross-site request forgery (CSRF) vulnerability in the login interface in MediaWiki 1.15 before 1.15.4 and 1.16 before 1.16 beta 3 allows remote attackers to hijack the authentication of users for requests that (1) create accounts or (2) reset passwords, related to the Special:Userlogin form.
MediaWiki before 1.15.3, and 1.6.x before 1.16.0beta2, does not properly handle a correctly authenticated but unintended login attempt, which makes it easier for remote authenticated users to conduct phishing attacks by arranging for a victim to login to the attacker's account and then execute a crafted user script, related to a "login CSRF" issue.
MediaWiki before 1.15.2 does not prevent wiki editors from linking to images from other web sites in wiki pages, which allows editors to obtain IP addresses and other information of wiki users by adding a link to an image on an attacker-controlled web site, aka "CSS validation issue."
thumb.php in MediaWiki before 1.15.2, when used with access-restriction mechanisms such as img_auth.php, does not check user permissions before providing scaled images, which allows remote attackers to bypass intended access restrictions and read private images via unspecified manipulations.
Cross-site scripting (XSS) vulnerability in the Special:Block implementation in the getContribsLink function in SpecialBlockip.php in MediaWiki 1.14.0 and 1.15.0 allows remote attackers to inject arbitrary web script or HTML via the ip parameter.
