Samuel Sidler reports :

WordPress 4.3.1 is now available. This is a security release for all previous versions and we strongly encourage you to update your sites immediately.

- WordPress versions 4.3 and earlier are vulnerable to a cross-site scripting vulnerability when processing shortcode tags (CVE-2015-5714). Reported by Shahar Tal and Netanel Rubin of Check Point.

- A separate cross-site scripting vulnerability was found in the user list table. Reported by Ben Bidner of the WordPress security team.

- Finally, in certain cases, users without proper permissions could publish private posts and make them sticky (CVE-2015-5715). Reported by Shahar Tal and Netanel Rubin of Check Point.

According to its version number, the WordPress application running on the remote web server is prior to 4.3.1. It is, therefore, potentially affected by multiple vulnerabilities :

  - A cross-site scripting vulnerability exists when     processing shortcode tags due to improper validation of     user-supplied input. An attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session. (CVE-2015-5714)

  - An unspecified vulnerability exists that allows an     authenticated attacker to publish private posts and make     them 'sticky'. (CVE-2015-5715)

  - An unspecified cross-site scripting vulnerability exists     in the user list table. An attacker can exploit this,     via a specially crafted request, to execute arbitrary     script code in a user's browser session.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Various security issue have been fixed in the Debian LTS (squeeze) version of the Wordpress content management system.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Versions of WordPress prior to 4.3.1 are susceptible to the following vulnerabilities : 

 - A cross-site scripting vulnerability exists when processing shortcode tags due to improper validation of user-supplied input.  An attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2015-5714)
 - A cross-site scripting (XSS) vulnerability affects the User List. This flaw exists because the program does not validate input to user list tables before returning it to users. (CVE-2015-7989)
 - An unspecified vulnerability exists that allows an authenticated attacker to publish private posts and make them 'sticky'. (CVE-2015-5715)
