Vulnerability from github – Published: 2024-03-13 18:31 – Updated: 2024-03-13 18:31

Details

This vulnerability is due to insufficient validation of arguments that are included with the SSH client CLI command. An attacker with low-privileged access to an affected device could exploit this vulnerability by issuing a crafted SSH client command to the CLI. A successful exploit could allow the attacker to elevate privileges to root on the affected device.

Severity ?

7.8 (High)
