According to its self-reported version number, the Symantec Messaging Gateway (SMG) running on the remote host is 10.x prior to 10.6.1. It is, therefore, affected by multiple vulnerabilities :
A privilege escalation vulnerability exists in the SMG management console due to AD password information being insecurely stored and encrypted. A local attacker who has read-level access can exploit this, by reverse engineering the encrypted AD password, to gain unauthorized, elevated access to additional resources on the network. Note that recovery of this password would not provide any additional access to the SMG appliance itself. (CVE-2016-2203)
A privilege escalation vulnerability exists due to an unspecified flaw in the SMG management console. A local attacker can exploit this, by manipulating code input to the terminal window, to gain access to the privileged root shell of the console. (CVE-2016-2204)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
