CVSS v3.1 |
| Cross-site scripting (XSS) vulnerability in MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2 allows remote attackers to inject arbitrary web script or HTML via a custom JavaScript file, which is not properly handled when previewing the file. |
| Cross-site scripting (XSS) vulnerability in MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2, when using HHVM, allows remote attackers to inject arbitrary web script or HTML via an invalid parameter in a wddx format request to api.php, which is not properly handled in an error message, related to unsafe calls to wddx_serialize_value. |
| MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2, when using HHVM, allows remote attackers to cause a denial of service (CPU and memory consumption) via a large number of nested entity references in an (1) SVG file or (2) XMP metadata in a PDF file, aka a "billion laughs attack," a different vulnerability than CVE-2015-2937. |
| Cross-site scripting (XSS) vulnerability in includes/actions/InfoAction.php in MediaWiki before 1.21.9 and 1.22.x before 1.22.6 allows remote attackers to inject arbitrary web script or HTML via the sort key in an info action. |
| The JSONP endpoint in includes/api/ApiFormatJson.php in MediaWiki before 1.19.18, 1.20.x through 1.22.x before 1.22.9, and 1.23.x before 1.23.2 accepts certain long callback values and does not restrict the initial bytes of a JSONP response, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks, and obtain sensitive information, via a crafted OBJECT element with SWF content consistent with a restricted character set. |
| MediaWiki before 1.16.1, when user or site JavaScript or CSS is enabled, allows remote attackers to conduct clickjacking attacks via unspecified vectors. |
| Unrestricted file upload vulnerability in the chunk upload API in MediaWiki 1.19 through 1.19.6 and 1.20.x before 1.20.6 allows remote attackers to execute arbitrary code by uploading a file with an executable extension. |
| The CentralAuth extension for MediaWiki 1.19.x before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 caches a valid CentralAuthUser object in the centralauth_User cookie even when a user has not successfully logged in, which allows remote attackers to bypass authentication without a password. |
| Cross-site scripting (XSS) vulnerability in contrib/example.php in the SyntaxHighlight GeSHi extension for MediaWiki, possibly as downloaded before September 2013, allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO. |
| Multiple cross-site request forgery (CSRF) vulnerabilities in MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 allow remote attackers to hijack the authentication of users with the block permission for requests that (1) block a user via a request to the Block module or (2) unblock a user via a request to the Unblock module. |
| Cross-site request forgery (CSRF) vulnerability in api/ApiQueryCheckUser.php in the CheckUser extension for MediaWiki, possibly Checkuser before 2.3, allows remote attackers to hijack the authentication of arbitrary users for requests that "perform sensitive write actions" via unspecified vectors. |
| Multiple cross-site scripting (XSS) vulnerabilities in repo/includes/EntityView.php in the Wikibase extension for MediaWiki 1.19.x before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 allow (1) remote attackers to inject arbitrary web script or HTML via a label in the "In other languages" section or (2) remote administrators to inject arbitrary web script or HTML via a description. |
| Incomplete blacklist vulnerability in Sanitizer::checkCss in MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 allows remote attackers to conduct cross-site scripting (XSS) attacks via certain non-ASCII characters in CSS, as demonstrated using variations of "expression" containing (1) full width characters or (2) IPA extensions, which are converted and rendered by Internet Explorer. |
| The CleanChanges extension for MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3, when "Group changes by page in recent changes and watchlist" is enabled, allows remote attackers to obtain sensitive information (revision-deleted IPs) via the Recent Changes page. |
| 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. |
| 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. |
| Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.3, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .html at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. |
| Cross-site scripting (XSS) vulnerability in the ZeroRatedMobileAccess extension for MediaWiki 1.19.x before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 allows remote attackers to inject arbitrary web script or HTML via the "to" parameter to index.php. |
| MediaWiki 1.22.x before 1.22.2, 1.21.x before 1.21.5, and 1.19.x before 1.19.11, when DjVu or PDF file upload support is enabled, allows remote attackers to execute arbitrary commands via shell metacharacters in (1) the page parameter to includes/media/DjVu.php; (2) the w parameter (aka width field) to thumb.php, which is not properly handled by includes/media/PdfHandler_body.php; and possibly unspecified vectors in (3) includes/media/Bitmap.php and (4) includes/media/ImageHandler.php. |
| 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." |
