CVE-2024-20370: Cisco Adaptive Security Appliance Software

Medium severity, CVSS 6.0. EPSS: 0.2% chance of exploitation in the next 30 days.

A vulnerability in the Cisco FXOS CLI feature on specific hardware platforms for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to elevate their administrative privileges to root. The attacker would need valid administrative credentials on the device to exploit this vulnerability. This vulnerability exists because certain system configurations and executable files have insecure storage and permissions. An attacker could exploit this vulnerability by authenticating on the device and then performing a series of steps that includes downloading malicious system files and accessing the Cisco FXOS CLI to configure the attack. A successful exploit could allow the attacker to obtain root access on the device.
