Descriptions
Symantec Advanced Secure Gateway (ASG) 6.6 and 6.7, and ProxySG 6.5, 6.6, and 6.7 are susceptible to a SAML authentication bypass vulnerability. The products can be configured with a SAML authentication realm to authenticate network users in intercepted proxy traffic. When parsing SAML responses, ASG and ProxySG incorrectly handle XML nodes with comments. A remote attacker can modify a valid SAML response without invalidating its cryptographic signature. This may allow the attacker to bypass user authentication security controls in ASG and ProxySG. This vulnerability only affects authentication of network users in intercepted traffic. It does not affect administrator user authentication for the ASG and ProxySG management consoles.
Symantec Advanced Secure Gateway (ASG) 6.6 y 6.7 y ProxySG 6.5, 6.6 y 6.7 son susceptibles a una vulnerabilidad de omisión de autenticación SAML. Los productos pueden configurarse con un realm de autenticación SAML para autenticar a usuarios de red en tráfico de proxy interceptado. Al parsear respuestas SAML, ASG y ProxySG gestionan incorrectamente los nodos XML con comentarios. Un atacante remoto puede modificar una respuesta SAML válida sin invalidar su firma criptográfica. Esto podría permitir que el atacante omita los controles de seguridad de autenticación en ASG y ProxySG. Esta vulnerabilidad solo afecta a la autenticación de usuarios de red en el tráfico interceptado. No afecta a la autenticación de usuario administrador en las consolas de gestión de ASG y ProxySG.
