VAR-201311-0234
Vulnerability from variot - Updated: 2025-04-11 23:12The Control and Provisioning of Wireless Access Points (CAPWAP) protocol implementation on Cisco Wireless LAN Controller (WLC) devices allows remote attackers to cause a denial of service via a crafted CAPWAP packet that triggers a buffer over-read, aka Bug ID CSCuh81880. Vendors have confirmed this vulnerability Bug ID CSCuh81880 It is released as.Skillfully crafted by a third party to induce buffer overread CAPWAP Service disruption via packets (DoS) There is a possibility of being put into a state. The vulnerability is caused by insufficient data packet verification, which allows a remote attacker to exploit a vulnerability to send a specially crafted CAPWAP message to the Cisco WLC. Successfully exploiting this issue allows remote attackers to cause denial-of-service conditions. This issue is being tracked by Cisco Bug ID CSCuh81880
