The version of the Symantec Endpoint Encryption (SEE) Drive Encryption Client installed on the remote Windows host is prior to 11.1.1.
It is, therefore, affected by a privilege escalation vulnerability due to an unquoted search path in EEDService. A local attacker can exploit this to escalate privileges.
