Vulnerability Overview

Multiple cross-site scripting (XSS) vulnerabilities in KSES, as used in WordPress before 3.0.4, allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) the & (ampersand) character, (2) the case of an attribute name, (3) a padded entity, and (4) an entity that is not in normalized form.

Technical Analysis

REMEDIATION: Update to version 3.0.4, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
