Title
Cisco Firepower Threat Defense Command Injection Vulnerabilities
Summary
A vulnerability in the CLI of Cisco FTD Software could allow an authenticated, local attacker with administrative privileges to execute arbitrary commands with root privileges on the underlying operating system of an affected device.
This vulnerability is due to insufficient validation of user-supplied command arguments. An attacker could exploit this vulnerability by submitting crafted input to the affected commands. A successful exploit could allow the attacker to execute commands with root privileges on the underlying operating system.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
