Multiple security issues have been discovered in Wordpress, a weblog manager, that could allow remote attackers to upload files with invalid or unsafe names, mount social engineering attacks or compromise a site via cross-site scripting, and inject SQL commands.

More information can be found in the upstream advisories at and

In the Debian squeeze-lts version of Wordpress, multiple security issues have been fixed :

Remote attackers could...

  - ... upload files with invalid or unsafe names

  - ... mount social engineering attacks

  - ... compromise a site via cross-site scripting

  - ... inject SQL commands

  - ... cause denial of service or information disclosure

CVE-2014-9031

Jouko Pynnonen discovered an unauthenticated cross site scripting vulnerability (XSS) in wptexturize(), exploitable via comments or posts.

CVE-2014-9033

Cross site request forgery (CSRF) vulnerability in the password changing process, which could be used by an attacker to trick an user into changing her password.

CVE-2014-9034

Javier Nieto Arevalo and Andres Rojas Guerrero reported a potential denial of service in the way the phpass library is used to handle passwords, since no maximum password length was set.

CVE-2014-9035

John Blackbourn reported an XSS in the 'Press This' function (used for quick publishing using a browser 'bookmarklet').

CVE-2014-9036

Robert Chapin reported an XSS in the HTML filtering of CSS in posts.

CVE-2014-9037

David Anderson reported a hash comparison vulnerability for passwords stored using the old-style MD5 scheme. While unlikely, this could be exploited to compromise an account, if the user had not logged in after a Wordpress 2.5 update (uploaded to Debian on 2 Apr, 2008) and the password MD5 hash could be collided with due to PHP dynamic comparison.

CVE-2014-9038

Ben Bidner reported a server side request forgery (SSRF) in the core HTTP layer which unsufficiently blocked the loopback IP address space.

CVE-2014-9039

Momen Bassel, Tanoy Bose, and Bojan Slavkovic reported a vulnerability in the password reset process: an email address change would not invalidate a previous password reset email.

CVE-2015-3438

Cedric Van Bockhaven reported and Gary Pendergast, Mike Adams, and Andrew Nacin of the WordPress security team fixed a cross-site-scripting vulnerabilitity, which could enable anonymous users to compromise a site. 

CVE-2015-3439

Jakub Zoczek discovered a very limited cross-site scripting vulnerability, that could be used as part of a social engineering attack.

CVE-2015-3440

Jouko Pynn&ouml;nen discovered a cross-site scripting vulnerability, which could enable commenters to compromise a site.

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

  - An unspecified flaw exists that allows an attacker to     upload arbitrary files with invalid or unsafe names.
    Note that this only affects versions 4.1 and higher.

  - A cross-site scripting vulnerability exists due to     improper validation of user-supplied input. A remote     attacker, using a specially crafted request, can exploit     this to execute arbitrary script code in a user's     browser session.

  - A limited cross-site scripting vulnerability exists due     to improper validation of user-supplied input. A remote     attacker, using a specially crafted request, can exploit     this to execute arbitrary script code in a user's     browser session. Note that this only affects versions     3.9 and higher.

  - An unspecified SQL injection vulnerability exists in     some plugins.

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

Versions of WordPress 3.7.x prior to 3.7.6 , 3.8.x prior to 3.8.6 , 3.9.x prior to 3.9.4 , and 4.1.x prior to 4.1.2 are susceptible to the following vulnerabilities : 

 - An unspecified flaw exists that allows an attacker to upload arbitrary files with invalid or unsafe names. Note that this only affects versions 4.1 and higher.
 - A cross-site scripting vulnerability exists due to improper validation of user-supplied input. A remote attacker, using a specially crafted request, can exploit this to execute arbitrary script code in a user's browser session.
