The file upload feature in Drupal 6.x before 6.27 and 7.x before 7.18 allows remote authenticated users to bypass the protection mechanism and execute arbitrary PHP code via a null byte in a file name.

Multiple vulnerabilities have been been fixed in the Drupal content management framework, resulting in information disclosure, insufficient validation, cross-site scripting and cross-site request forgery.

Updated drupal packages fix security vulnerabilities :

Drupal core's text filtering system provides several features including removing inappropriate HTML tags and automatically linking content that appears to be a link. A pattern in Drupal's text matching was found to be inefficient with certain specially crafted strings.
This vulnerability is mitigated by the fact that users must have the ability to post content sent to the filter system such as a role with the post comments or Forum topic: Create new content permission (CVE-2012-1588).

Drupal core's Form API allows users to set a destination, but failed to validate that the URL was internal to the site. This weakness could be abused to redirect the login to a remote site with a malicious script that harvests the login credentials and redirects to the live site. This vulnerability is mitigated only by the end user's ability to recognize a URL with malicious query parameters to avoid the social engineering required to exploit the problem (CVE-2012-1589).

Drupal core's forum lists fail to check user access to nodes when displaying them in the forum overview page. If an unpublished node was the most recently updated in a forum then users who should not have access to unpublished forum posts were still be able to see meta-data about the forum post such as the post title (CVE-2012-1590).

Drupal core provides the ability to have private files, including images, and Image Styles which create derivative images from an original image that may differ, for example, in size or saturation.
Drupal core failed to properly terminate the page request for cached image styles allowing users to access image derivatives for images they should not be able to view. Furthermore, Drupal didn't set the right headers to prevent image styles from being cached in the browser (CVE-2012-1591).

Drupal core provides the ability to list nodes on a site at admin/content. Drupal core failed to confirm a user viewing that page had access to each node in the list. This vulnerability only concerns sites running a contributed node access module and is mitigated by the fact that users must have a role with the Access the content overview page permission. Unpublished nodes were not displayed to users who only had the Access the content overview page permission (CVE-2012-2153).

The request_path function in includes/bootstrap.inc in Drupal 7.14 and earlier allows remote attackers to obtain sensitive information via the q[] parameter to index.php, which reveals the installation path in an error message (CVE-2012-2922).

A bug in the installer code was identified that allows an attacker to re-install Drupal using an external database server under certain transient conditions. This could allow the attacker to execute arbitrary PHP code on the original server (Drupal SA-CORE-2012-003).

For sites using the core OpenID module, an information disclosure vulnerability was identified that allows an attacker to read files on the local filesystem by attempting to log in to the site using a malicious OpenID server (Drupal SA-CORE-2012-003).

A vulnerability was identified that allows blocked users to appear in user search results, even when the search results are viewed by unprivileged users (CVE-2012-5651).

Drupal core's file upload feature blocks the upload of many files that can be executed on the server by munging the filename. A malicious user could name a file in a manner that bypasses this munging of the filename in Drupal's input validation (CVE-2012-5653).

Multiple vulnerabilities were fixed in the supported Drupal core version 7 (DRUPAL-SA-CORE-2013-001).

A reflected cross-site scripting vulnerability (XSS) was identified in certain Drupal JavaScript functions that pass unexpected user input into jQuery causing it to insert HTML into the page when the intended behavior is to select DOM elements. Multiple core and contributed modules are affected by this issue.

A vulnerability was identified that exposes the title or, in some cases, the content of nodes that the user should not have access to.

Drupal core provides the ability to have private files, including images. A vulnerability was identified in which derivative images (which Drupal automatically creates from these images based on image styles and which may differ, for example, in size or saturation) did not always receive the same protection. Under some circumstances, this would allow users to access image derivatives for images they should not be able to view.

The drupal package was updated to latest version 7.19 to fix above vulnerabilities.

Upstream Drupal has reported SA-CORE-2012-004 [1] which corrects multiple vulnerabilities :

1) Access bypass (User module search - Drupal 6 and 7) 2) Access bypass (Upload module - Drupal 6) 3) Arbitrary PHP code execution (File upload modules - Drupal 6 and 7)

CVEs have been requested and are not yet assigned.

These flaws have been fixed in Drupal 6.27 and 7.18.

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

The remote web server is running a version of Drupal that is 6.x prior to 6.27 or 7.x prior to 7.18. It is, therefore, potentially affected by multiple vulnerabilities :

  - An access bypass vulnerability exists that allows search     results to improperly display information about blocked     users. (CVE-2012-5651)

  - Version 6.x is affected by an information disclosure     vulnerability that allows information about uploaded     files to be displayed in RSS feeds and search results     for users that do not have the 'view uploaded files'     permission. (CVE-2012-5652)

  - An arbitrary code execution vulnerability exists due to     a failure to properly verify user-uploaded files. A     remote, authenticated attacker, using a specially named     PHP file, can bypass input validation checks, and the     uploaded file can then be executed with the privileges     of the web server user. (CVE-2012-5653)

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