Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4421)

The vulnerability allows a remote #AU# to manipulate data.

The create_post function in wp-includes/class-wp-atom-server.php in WordPress before 3.4.2 does not perform a capability check, which allows remote authenticated users to bypass intended access restrictions and publish new posts by leveraging the Contributor role and using the Atom Publishing Protocol (aka AtomPub) feature.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4422)

The vulnerability allows a remote #AU# to manipulate data.

wp-admin/plugins.php in WordPress before 3.4.2, when the multisite feature is enabled, does not check for network-administrator privileges before performing a network-wide activation of an installed plugin, which might allow remote authenticated users to make unintended plugin changes by leveraging the Administrator role.


3) Cross-site scripting (CVE-ID: CVE-2012-3383)

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. The vulnerability allows remote authenticated users to bypass intended access restrictions and conduct cross-site scripting (XSS) attacks by leveraging the Administrator or Editor role and composing crafted text.

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.
