Cisco Firepower Management Center Software Command Injection Vulnerability [CVE-2023-20048]

CVE – CVE-2023-20048

A vulnerability in the web services interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute certain unauthorized configuration commands on a Firepower Threat Defense (FTD) device that is managed by the FMC Software.

This vulnerability is due to insufficient authorization of configuration commands that are sent through the web service interface. An attacker could exploit this vulnerability by authenticating to the FMC web services interface and sending a crafted HTTP request to an affected device.

A successful exploit could allow the attacker to execute certain configuration commands on the targeted FTD device. To successfully exploit this vulnerability, an attacker would need valid credentials on the FMC Software.

Cisco has released software updates that address this vulnerability.

At the time of publication there are no workarounds that address this vulnerability.

To help customers determine their exposure to vulnerabilities in Cisco ASA, FMC, and FTD Software, Cisco provides the Cisco Software Checker. This tool identifies any Cisco security advisories that impact a specific software release and the earliest release that fixes the vulnerabilities that are described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities that are described in all the advisories that the Software Checker identifies (“Combined First Fixed”).
