Description

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Software could allow an authenticated, remote attacker to inject and execute arbitrary commands with root privileges on an affected device. The vulnerability is due to insufficient validation of command input by the affected software. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to inject and execute arbitrary, system-level commands with root privileges on an affected device.
