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.

According to its self-reported version number, the WordPress application running on the remote web server is prior to 3.0.4.
It is, therefore, affected by multiple cross-site scripting (XSS) vulnerabilities in KSES. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.

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

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.
