Technical description

A vulnerability in the SSH management feature of multiple Cisco Access Points (APs) platforms could allow a local, authenticated user to modify files on the affected device and possibly gain escalated privileges.

A successful exploit could allow the attacker to gain privileges equivalent to the root user.
