Description

A vulnerability in the web-based management interface of Cisco Secure Firewall Management Center (FMC) Software could allow an authenticated remote attacker with Administrator-level privileges to execute arbitrary commands on the underlying operating system.

An attacker could exploit this vulnerability by authenticating to the interface and sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to execute commands as the root user on the affected device. To exploit this vulnerability an attacker would need Administrator-level credentials.
