Multiple vulnerabilities in the CLI of Cisco FTD Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges on the underlying operating system of an affected device that is running in multi-instance mode.
These vulnerabilities are due to insufficient validation of user-supplied command arguments. An attacker could exploit these vulnerabilities by submitting crafted input to the affected command.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
