"According to its self-reported version, Cisco Wireless LAN Controller
(WLC) is affected by following vulnerability
- A vulnerability in certain access control mechanisms for
the Secure Shell (SSH) server implementation for Cisco
Wireless LAN Controller (WLC) Software could allow an
unauthenticated, adjacent attacker to access a CLI
instance on an affected device.The vulnerability is due
to a lack of proper input- and validation-checking
mechanisms for inbound SSH connections on an affected
device. An attacker could exploit this vulnerability by
attempting to establish an SSH connection to an affected
controller. An exploit could allow the attacker to
access an affected device's CLI to potentially cause
further attacks. (CVE-2019-1805)
