Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Cross-site request forgery (CVE-ID: CVE-2014-3454)
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 perform arbitrary actions on behalf of the victim on the vulnerable website.
2) Cross-site request forgery (CVE-ID: CVE-2014-3455)
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 perform arbitrary actions on behalf of the victim on the vulnerable website.
3) Cross-site scripting (CVE-ID: CVE-2013-6452)
Vulnerability allows a remote attacker to perform Cross-site scripting attacks.
An input validation error exists in MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1. 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.
4) Input validation error (CVE-ID: CVE-2013-6453)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1 does not properly sanitize SVG files, which allows remote attackers to have unspecified impact via invalid XML.
5) Cross-site scripting (CVE-ID: CVE-2013-6454)
Vulnerability allows a remote attacker to perform XSS attacks.
The vulnerability is caused by an input validation error in MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1. 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.
6) Information disclosure (CVE-ID: CVE-2013-6472)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1 allows remote attackers to obtain information about deleted page via the (1) log API, (2) enhanced RecentChanges, and (3) user watchlists.
7) Input validation error (CVE-ID: CVE-2013-4570)
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and crash) via vectors related to converting Lua data structures to PHP, as demonstrated by passing { [{}] = 1 } to a module function.
8) Buffer overflow (CVE-ID: CVE-2013-4571)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Buffer overflow in php-luasandbox in the Scribuntu extension for MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1 has unspecified impact and remote vectors.
9) Cross-site scripting (CVE-ID: CVE-2013-4574)
Vulnerability allows a remote attacker to perform Cross-site scripting attacks.
An input validation error exists in the TimeMediaHandler extension for MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1. 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.
