Detailsinfo

A vulnerability has been found in Cisco Wireless LAN Controller 2.0 (Wireless LAN Software) and classified as problematic. This vulnerability affects an unknown code block of the component ANQP Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability. CVE summarizes:

A vulnerability in the Access Network Query Protocol (ANQP) ingress frame processing functionality of Cisco Wireless LAN Controllers could allow an unauthenticated, Layer 2 RF-adjacent attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete input validation of ANQP query frames by the affected device. An attacker could exploit this vulnerability by sending a malformed ANQP query frame to an affected device that is on an RF-adjacent network. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition. This vulnerability affects Cisco Wireless LAN Controllers that are running a vulnerable release of Cisco WLC Software and are configured to support Hotspot 2.0. Cisco Bug IDs: CSCve05779.

The bug was discovered 11/01/2017. The weakness was shared 11/02/2017 as cisco-sa-20171101-wlc4 as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability was named CVE-2017-12282 since 08/03/2017. Access to the local network is required for this attack. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.
