UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary

Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

During internal review, it was discovered that MediaWiki's SVG sanitization could be bypassed when the XML was considered invalid (CVE-2013-6453). During internal review, it was discovered that MediaWiki displayed some information about deleted pages in the log API, enhanced RecentChanges, and user watchlists (CVE-2013-6472). Netanel Rubin from Check Point discovered a remote code execution vulnerability in MediaWiki's thumbnail generation for DjVu files. Internal review also discovered similar logic in the PdfHandler extension, which could be exploited in a similar way (CVE-2014-1610). MediaWiki before 1.22.3 does not block unsafe namespaces, such as a W3C XHTML namespace, in uploaded SVG files. Some client software may use these namespaces in a way that results in XSS. This was fixed by disallowing uploading SVG files using non-whitelisted namespaces (CVE-2014-2242). MediaWiki before 1.22.3 performs token comparison that may be vulnerable to timing attacks. This was fixed by making token comparison use constant time (CVE-2014-2243). MediaWiki before 1.22.3 could allow an attacker to perform XSS attacks, due to flaw with link handling in api.php. This was fixed such that it won't find links in the middle of api.php links (CVE-2014-2244). MediaWiki has been updated to version 1.22.3, which fixes these issues, as well as several others. Also, the mediawiki-ldapauthentication and mediawiki-math extensions have been updated to newer versions that are compatible with MediaWiki 1.22. Additionally, the mediawiki-graphviz extension has been obsoleted, due to the fact that it is unmaintained upstream and is vulnerable to cross-site scripting attacks.

It is, therefore, affected by multiple vulnerabilities in MediaWiki : - A cross-site scripting (XSS) vulnerability exists due to a failure to validate input before returning it to the user. An unauthenticated, remote attacker can exploit this, via specially crafted SVG files, to execute arbitrary script code in the user's browser session. (CVE-2013-2031) - A flaw exists in the password blocking mechanism due to two different tools being used to block password change requests, these being Special:PasswordReset and Special:ChangePassword, either of which may be bypassed by the method the other prevents. A remote attacker can exploit this issue to change passwords. (CVE-2013-2032) - Multiple flaws exist in Sanitizer::checkCss due to the improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit these to bypass the blacklist. (CVE-2013-4567, CVE-2013-4568) - A flaw exists due to multiple users being granted the same session ID within HTTP headers. A remote attacker can exploit this to authenticate as another random user. (CVE-2013-4572) - A cross-site scripting (XSS) vulnerability exists in the /includes/libs/XmlTypeCheck.php script due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted XSL file, to execute arbitrary script code in the user's browser session. (CVE-2013-6452) - A flaw exists in the /includes/upload/UploadBase.php script due to a failure to apply SVG sanitization when XML files are read as invalid. An unauthenticated, remote attacker can exploit this to upload non-sanitized XML files, resulting in an unspecified impact. (CVE-2013-6453) - A stored cross-site (XSS) scripting vulnerability exists in the /includes/Sanitizer.php script due to a failure to properly validate the '-o-link' attribute before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in the user's browser session. (CVE-2013-6454) - A flaw exists in the log API within the /includes/api/ApiQueryLogEvents.php script that allows an unauthenticated, remote attacker to disclose potentially sensitive information regarding deleted pages. (CVE-2013-6472) - Multiple flaws exist in the PdfHandler_body.php, DjVu.php, Bitmap.php, and ImageHandler.php scripts when DjVu or PDF file upload support is enabled due to improper sanitization of user-supplied input. An authenticated, remote attacker can exploit these, via the use of shell metacharacters, to execute execute arbitrary shell commands. (CVE-2014-1610) - A cross-site request forgery (XSRF) vulnerability exists in the includes/specials/SpecialChangePassword.php script due to a failure to properly handle a correctly authenticated but unintended login attempt. An unauthenticated, remote attacker, by convincing a user to follow a specially crafted link, can exploit this to reset the user's password.
