The Incutio XML-RPC (IXR) Library, as used in WordPress before 3.9.2 and Drupal 6.x before 6.33 and 7.x before 7.31, does not limit the number of elements in an XML document, which allows remote attackers to cause a denial of service (CPU consumption) via a large document, a different vulnerability than CVE-2014-5265.

Versions of WordPress 3.7.x prior to 3.7.4 , 3.8.x prior to 3.8.4 , and 3.9.x prior to 3.9.2 are susceptible to the following vulnerabilities : 

  - An XML injection flaw exists within 'getid3.lib.php' due to the parser accepting XML external entities from untrusted sources. Using specially crafted XML data, a remote attacker could access sensitive information or cause a denial of service. This affects versions 3.6 - 3.9.1, except 3.7.4 and 3.8.4.
 - An XML injection flaw exists within 'xmlrpc.php' due to the parser accepting XML internal entities without properly validating them. Using specially crafted XML data, a remote attacker could cause a denial of service. This affects versions 1.5 - 3.9.1, except 3.7.4 and 3.8.4.
 - An unsafe serialization flaw exists in the script '/src/wp-includes/class-wp-customize-widgets.php' when processing widgets. This could allow a remote attacker to execute arbitrary code. Versions 3.9 and 3.9.1 non-default configurations are affected.
 - A flaw exists when building CSRF tokens due to it not separating pieces by delimiter and not comparing nonces in a time-constant manner. This could allow a remote attacker to conduct a brute force attack and potentially disclose the CSRF token. This affects versions 2.0.3 - 3.9.1, except 3.7.4 and 3.8.4.
 - A cross-site scripting flaw exists in the function 'get_avatar' within the '/src/wp-includes/pluggable.php' script where input from the avatars is not validated before returning it to the user. Using a specially crafted request, an authenticated attacker could execute arbitrary script code within the browser / server trust relationship. This affects version 3.9.1.

The remote web server is running a version of Drupal that is 6.x prior to 6.33 or 7.x prior to 7.31. It is, therefore, potentially affected by multiple denial of service vulnerabilities :

  - The XML-RPC library in Drupal allows entity declarations     without considering recursion during entity expansion.
    A remote attacker, using a crafted XML document with a     large number of nested entity references, can cause a     denial of service by consuming available memory and CPU     resources. (CVE-2014-5265)

  - The XML-RPC library in Drupal does not limit the number     of elements in an XML document. A remote attacker, via     a large document, could cause a denial of service by CPU     consumption. (CVE-2014-5266)

  - An XML injection flaw exists in 'xmlrpc.php' due to the     parser accepting XML internal entities from untrusted     sources. A remote attacker, via specially crafted XML     data, could exploit this to cause a denial of service.
    This vulnerability also exists within the Drupal OpenID     module.

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

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

  - An XML injection flaw exists within 'getid3.lib.php'     due to the parser accepting XML external entities     from untrusted sources. Using specially crafted XML     data, a remote attacker could access sensitive     information or cause a denial of service. This affects     versions 3.6 - 3.9.1, except 3.7.4 and 3.8.4.

  - An XML injection flaw exists within 'xmlrpc.php' due to     the parser accepting XML internal entities without     properly validating them. Using specially crafted XML     data, a remote attacker could cause a denial of service.
    This affects versions 1.5 - 3.9.1, except 3.7.4 and     3.8.4.

  - An unsafe serialization flaw exists in the script     '/src/wp-includes/class-wp-customize-widgets.php' when     processing widgets. This could allow a remote attacker     to execute arbitrary code. Versions 3.9 and 3.9.1     non-default configurations are affected.

  - A flaw exists when building CSRF tokens due to it not     separating pieces by delimiter and not comparing nonces     in a time-constant manner. This could allow a remote     attacker to conduct a brute force attack and potentially     disclose the CSRF token. This affects versions 2.0.3 -     3.9.1, except 3.7.4 and 3.8.4.

  - A cross-site scripting flaw exists in the function     'get_avatar' within the '/src/wp-includes/pluggable.php'     script where input from the avatars is not validated     before returning it to the user. Using a specially     crafted request, an authenticated attacker could execute     arbitrary script code within the browser / server trust     relationship. This affects version 3.9.1.

A denial of service vulnerability was discovered in Drupal, a fully-featured content management framework. A remote attacker could exploit this flaw to cause CPU and memory exhaustion and the site's database to reach the maximum number of open connections, leading to the site becoming unavailable or unresponsive.
