medium Nessus Plugin ID 131699


The remote device is missing a vendor-supplied security patch


According to its self-reported version, Cisco FXOS Software is affected by a command injection vulnerability due to insufficient validation of arguments passed to certain CLI commands. An authenticated, local attacker with valid administrator credentials can exploit this by including malicious input as the argument of an affected command in order to execute arbitrary commands on the underlying operating system with elevated privileges.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
