TITLE: WordPress "style" Cross-Site Scripting

SECUNIA ADVISORY ID: SA26296

VERIFY ADVISORY: link://[click]

CRITICAL: Less critical

IMPACT: Cross Site Scripting

WHERE: From remote SOFTWARE: WordPress 2.x link://[click]

DESCRIPTION: Benjamin Flesch has discovered a vulnerability in WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "style" parameter in wp-admin/upload.php (when "post_id" is set to a negative integer value) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Successful exploitation requires that the target user has valid author or higher credentials.

The vulnerability is confirmed in version 2.2.1. Other versions may also be affected.

SOLUTION: Edit the source code to ensure that input is properly sanitised.
