"According to its self-reported version, Cisco Identity Services Engine Software is affected by a local file inclusion
vulnerability. A vulnerability in the restricted shell of Cisco Identity Services Engine (ISE) could allow an
authenticated, local attacker to identify directories and write arbitrary files to the file system. This vulnerability
is due to improper validation of parameters that are sent to a CLI command within the restricted shell. An attacker
could exploit this vulnerability by logging in to the device and issuing certain CLI commands. A successful exploit
could allow the attacker to identify file directories on the affected device and write arbitrary files to the file
system on the affected device. To exploit this vulnerability, the attacker must be an authenticated shell user.

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