2) Cross-site scripting (CVE-ID: CVE-2014-5242)
Vulnerability allows a remote attacker to perform Cross-site scripting attacks.
An input validation error exists in mediawiki.page.image.pagination.js in MediaWiki 1.22.x before 1.22.9 and 1.23.x before 1.23.2. A remote authenticated 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.
3) Input validation error (CVE-ID: CVE-2014-5243)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
MediaWiki before 1.19.18, 1.20.x through 1.22.x before 1.22.9, and 1.23.x before 1.23.2 does not enforce an IFRAME protection mechanism for transcluded pages, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site.
4) Cross-site scripting (CVE-ID: CVE-2014-7199)
Vulnerability allows a remote attacker to perform Cross-site scripting attacks.
An input validation error exists in MediaWiki before 1.19.19, 1.22.x before 1.22.11, and 1.23.x before 1.23.4. A remote authenticated 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.
5) Cross-site scripting (CVE-ID: CVE-2014-7295)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data passed via "The (1) Special:Preferences and (2) Special:UserLogin pages" when modifying MediaWiki:Common.css. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in 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.
