AI risk analysis

Summary
This vulnerability allows an attacker to perform command injection attacks and elevate privileges to root through the web-based management interface of Cisco ISE and ISE-PIC, leading to potential code execution and denial of service.
Exploitability
Exploitation requires valid administrative credentials and sending crafted commands, making it moderately hard to exploit.
Blast radius
If exploited, this could result in arbitrary code execution and a denial of service condition, impacting network availability and security.

NVD description

A vulnerability in the diagnostic tools of Cisco ISE and ISE-PIC could allow an authenticated, remote attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the device and elevate privileges to root. In single-node deployments, successful exploitation of this vulnerability could cause the affected ISE node to become unavailable, resulting in a denial of service (DoS) condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored.
