CVE-2024-20306 [Medium] | Input Validation Bypass in Ios Xe

A vulnerability in the Unified Threat Defense (UTD) configuration CLI of Cisco IOS XE Software could allow an authenticated, local attacker to execute arbitrary commands as root on the underlying host operating system. To exploit this vulnerability, an attacker must have level 15 privileges on the affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by submitting a crafted CLI command to an affected device. A successful exploit could allow the attacker to execute arbitrary commands as root on the underlying operating system.
