"According to its self-reported version, Cisco Firepower Device Manager (FDM) On-Box software is affected by a
vulnerability in the REST API that allows an authenticated, remote attacker to execute arbitrary code on the underlying
operating system of an affected device. This vulnerability is due to insufficient sanitization of user input on specific
REST API commands. An attacker could exploit this vulnerability by sending a crafted HTTP request to the API subsystem
of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying
operating system. To exploit this vulnerability, an attacker would need valid low-privileged user credentials.

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