TITLE

Cisco WLC of NPU Denial of service in Japan (DoS) Vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2007-001826

DESCRIPTION

The Network Processing Unit (NPU) in the Cisco Wireless LAN Controller (WLC) before 3.2.171.5, 4.0.x before 4.0.206.0, and 4.1.x allows remote attackers on a local wireless network to cause a denial of service (loss of packet forwarding) via (1) crafted SNAP packets, (2) malformed 802.11 traffic, or (3) packets with certain header length values, aka Bug IDs CSCsg15901 and CSCsh10841. Cisco Wireless LAN Controller (WLC) is prone to multiple remote vulnerabilities, including an unauthorized-access vulnerability, an information-disclosure vulnerability, and a vulnerability that prevents the WLAN's ACLs from being installed. An attacker can exploit these issues to completely compromise the affected device, cause a denial-of-service condition, obtain potentially sensitive information, and gain unauthorized access to the affected device. Cisco Wireless LAN Controllers (WLCs) manage Cisco Aironet access points using the Lightweight Access Point Protocol (LWAPP). Multiple NPU Lock-Up Vulnerabilities +----------------------------- The Network Processing Unit (NPU) is responsible for handling communication in the WLC. One or more NPUs may lock up if certain types of traffic are sent to the affected WLC. These communications include specially crafted SNAP packets, malformed 802.11 communications, and packets with unexpected length values ​​in some headers. Each NPU operates independently, servicing two physical ports on the WLC, and locking one NPU does not affect the other, so the number of NPUs available and device configuration determine whether these vulnerabilities can result in partial or complete inability to forward traffic. If you want to clear the NPU lock, you must restart the WLC. If a lockout prevents access to the management interface, a reboot must be performed through the console port or the service port. These vulnerabilities are documented in Cisco Bug IDs as CSCsg36361, CSCsg15901, and CSCsh10841
