Affected Products:



Multiple persistent Input Validation Vulnerabilities are detected on the Astaros Security Gateway application(appliance).
The vulnerability allows a local low privileged user account or remote attacker with medium required user inter action to manipulate 
module contexts on application-side.  Result of successful exploitation is session hijacking, phishing & stable context manipulation
or client side target exploitation out of the gateway web application context.

Vulnerable Module(s):

			---- Management
  				-- System Settings (Time&Date | Shell Access) 

			---- Users
				  -- New User
				  -- New Group
				  -- Authentication / New Server

			---- Definitions
				  -- New Interface
				  -- Comment Static Route
				  -- OSPF Interface Settings
				  -- View/Edit Traffic Selector
 				  -- New PIM-SM Interface
				  -- New Rendezvous Point Router
				  -- Uplink Monitoring

			---- Network
