Description

An authenticated, remote attacker can exploit this by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to obtain hashed credentials of system users. To exploit this vulnerability an attacker would need to have valid user credentials with elevated privileges.
