Source: CVE Program / CVE List V5
Vulnerability Description
A vulnerability in the key-based SSH authentication feature of Cisco StarOS Software could allow an authenticated, remote attacker to elevate privileges on an affected device.
This vulnerability is due to insufficient validation of user-supplied credentials. An attacker could exploit this vulnerability by sending a valid low-privileged SSH key to an affected device from a host that has an IP address that is configured as the source for a high-privileged user account. A successful exploit could allow the attacker to log in to the affected device through SSH as a high-privileged user.
There are workarounds that address this vulnerability.
