Blue Coat Proxy Security Gateway OS (SGOS) 4.1.2.1 does not enforce CONNECT rules when using Deep Content Inspection, which allows remote attackers to bypass connection filters.

Blue Coat ProxySG before SGOS 4.3.4.1, 5.x before SGOS 5.4.5.1, 5.5 before SGOS 5.5.4.1, and 6.x before SGOS 6.1.1.1 allows remote authenticated users to execute arbitrary CLI commands by leveraging read-only administrator privileges and establishing an HTTPS session.
