Cisco Wireless LAN Controller Software Control and Provisioning of Wireless Access Points Protocol Information Disclosure Vulnerability

view advisory published 2018-10-17

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol component of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to retrieve memory contents, which could lead to the disclosure of confidential information. The vulnerability is due to insufficient condition checks in the part of the code that handles CAPWAP keepalive requests. An attacker could exploit this vulnerability by sending a crafted CAPWAP keepalive packet to a vulnerable Cisco WLC device. A successful exploit could allow the attacker to retrieve the contents of device memory, which could lead to the disclosure of confidential information. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
