Name of the Vulnerable Software and Affected Versions Cisco Firepower Threat Defense (FTD) Software (affected versions not specified)

Description A vulnerability in the multi-instance feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to escape the container for their Cisco FTD instance and execute commands with root privileges in the host namespace. The attacker must have valid credentials on the device. The vulnerability exists because a configuration file that is used at container startup has insufficient protections. An attacker could exploit this vulnerability by modifying a specific container configuration file on the underlying file system. A successful exploit could allow the attacker to execute commands with root privileges within the host namespace, potentially impacting other running Cisco FTD instances or the host Cisco FXOS device.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
