Descriptions

Multiple cross-site scripting (XSS) vulnerabilities in PHP scripts in the management console on Symantec Web Gateway (SWG) appliances with software before 5.2.2 DB 5.0.0.1277 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors, as demonstrated an attack against admin_messages.php.

Múltiples vulnerabilidades de XSS en scripts PHP en la consola de gestión en Symantec Web Gateway (SWG) en dispositivos con software en versiones anteriores a 5.2.2 DB 5.0.0.1277, permite a atacantes remotos inyectar secuencias de comandos web o HTML arbitrarios a través de vectores no especificados, según lo demostrado en un ataque contra admin_messages.php.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Symantec Web Gateway. Authentication is required to exploit this vulnerability, however it can be bypassed via reflected cross-site scripting.
The specific flaw exists within the admin_messages.php file which relies on mimetypes and file extensions to block potentially dangerous file uploads. An attacker can exploit this condition to upload arbitrary files as the apache user. Due to loose sudo restrictions, an attacker can add the setuid attribute and execute arbitrary code under the context of root.
