Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2013-0235)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The XMLRPC API in WordPress before 3.5.1 allows remote attackers to send HTTP requests to intranet servers, and conduct port-scanning attacks, by specifying a crafted source URL for a pingback, related to a Server-Side Request Forgery (SSRF) issue. Per: http://cwe.mitre.org/data/definitions/918.html 'CWE-918: Server-Side Request Forgery (SSRF)'


2) Cross-site scripting (CVE-ID: CVE-2013-0236)

Vulnerability allows a remote attacker to perform Cross-site scripting attacks.

An input validation error exists in WordPress before 3.5.1 when processing vectors involving (1) gallery shortcodes or (2) the content of a post. 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.


3) Information disclosure (CVE-ID: CVE-2012-5868)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

WordPress 3.4.2 does not invalidate a wordpress_sec session cookie upon an administrator's logout action, which makes it easier for remote attackers to discover valid session identifiers via a brute-force attack, or modify data via a replay attack.


4) Cross-site request forgery (CVE-ID: CVE-2012-4448)

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.
