Update to upstream release 2.9.2, fixing one security issue :

  - CVE-2010-0682     https://core.trac.wordpress.org/changeset/13117

plus a backported security fix :

  - CVE-2010-4257     https://core.trac.wordpress.org/changeset/16625

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.

Vladimir Kolesnikov discovered a SQL injection vulnerability in WordPress, a weblog manager. An authenticated user could execute arbitrary SQL commands via the Send Trackbacks field.

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

  - A SQL injection vulnerability exists in the     'wp-includes/comment.php' script due to improper     sanitization of user-supplied input to the 'Send     Trackbacks' field. A remote attacker can exploit this to     inject or manipulate SQL queries to manipulate or     disclose arbitrary data. (CVE-2010-4257)

  - A cross-site scripting vulnerability exists in the     request_filesystem_credentials() function in the     'wp-admin/includes/file.php' script where input passed     from an error message for an FTP or SSH connection     attempt is not validated. This allows a     context-dependent attacker to use a specially crafted     request to execute arbitrary script code within the     user's browser session. (CVE-2010-5294)

  - A cross-site scripting vulnerability exists in the     'wp-admin/plugins.php' script due to improper validation     of input supplied via a plugin's 'author' field. This     allows a remote attacker to inject arbitrary script or     HTML code in a user's browser session. (CVE-2010-5295)

  - A security bypass vulnerability exists in the     'wp-includes/capabilities.php' script. When a multisite     configuration is used, Super Admin privileges are not     needed for the 'delete_users' capability. This allows an     authenticated attacker to bypass access restrictions.
    (CVE-2010-5296)

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

Vendor reports :

SQL injection vulnerability in the do_trackbacks function in wp-includes/comment.php in WordPress before 3.0.2 allows remote authenticated users to execute arbitrary SQL commands via the Send Trackbacks field.

Versions of WordPress prior to 3.0.2 are susceptible to the following vulnerabilities :

 - A flaw exists that may allow an attacker to carry out an SQL injection attack.  The issue is due to the 'wp-includes/comment.php script' not properly sanitizing user-supplied input to the 'Send Trackbacks' field.  This may allow an attacker to inject or manipulate SQL queries in the back-end database, allowing for the manipulation or disclosure of arbitrary data. (CVE-2010-4257)
 - A flaw exists in the 'wp-includes/comment.php' script.  The issue is due to the program failing to properly whitelist trackbacks and pingbacks in the blogroll.  With a specially crafted URL, a remote attacker can bypass intended spam restrictions. (CVE-2010-5293)
 - A flaw exists that allows a reflected cross-site scripting (XSS) attack.  This flaw exists because the 'request_filesystem_credentials' function in the 'wp-admin/includes/file.php' script does not validate input passed via an error message for a FTP or SSH connection attempt.  This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2010-5294)
 - A flaw exists in 'wp-admin/plugins.php' that does not properly filter HTML code from user-supplied input before displaying the input.  A remote user can cause arbitrary scripting code to be executed by the target user's browser.  The code will originate from the site running the WordPress software and will run in the security context of that site.  As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user. (CVE-2010-5295)
 - A flaw exists in the 'wp-includes/capabilities.php' script when a multisite configuration is used.  The issue is triggered as the program doesn't require Super Admin privileges for the 'delete_users' capability.  This may allow a remote authenticated attacker to delete an action and bypass access restrictions. (CVE-2010-5296)
