Detailsinfo

A vulnerability was found in Cisco Wireless LAN Controller (Wireless LAN Software) (version now known). It has been declared as problematic. This vulnerability affects some unknown processing of the component SSH Session Management. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. CVE summarizes:

A vulnerability in the Secure Shell (SSH) session management for Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability exists because the SSH process is not properly deleted when an SSH connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly opening SSH connections to an affected device. A successful exploit could allow the attacker to exhaust system resources by initiating multiple SSH connections to the device that are not effectively terminated, which could result in a DoS condition.

The weakness was published 10/16/2019 as cisco-sa-20191016-wlc-ssh-dos as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com.
