Additional Product Information
The ProxySG and ASG management consoles provide a web-based interface for authenticated administrators to configure, manage, and monitor the respective appliance. Both products define separate read-only and read-write authorization levels for authenticated administrators. Read-only administrators can only view appliance settings and policy configuration, but not modify them. They can also perform limited troubleshooting tasks. Read-write administrators have full access to the appliance settings and policy configuration. They can also perform all management tasks available through the management console.
The ProxySG and ASG management consoles do not, under certain circumstances, correctly check the authorization of read-only administrator users. A malicious administrator with read-only access can exploit this vulnerability to access management console functionality that requries read-write access privileges.
