CVE-2024-20424

CRITICAL
Published Oct 23, 2024 Modified Nov 1, 2024 CWE-78

Description

A vulnerability in the web-based management interface of Cisco Secure Firewall Management Center (FMC) Software, formerly Firepower Management Center Software, could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system as root. This vulnerability is due to insufficient input validation of certain HTTP requests. An attacker could exploit this vulnerability by authenticating to the web-based management interface of an affected device and then sending a crafted HTTP request to the device. A successful exploit could allow the attacker to execute arbitrary commands with root permissions on the underlying operating system of the Cisco FMC device or to execute commands on managed Cisco Firepower Threat Defense (FTD) devices. To exploit this vulnerability, the attacker would need valid credentials for a user account with at least the role of Security Analyst (Read Only).
