Cisco Wireless LAN Controller (WLC) vulnerabilities

Cisco Wireless LAN Controller (WLC) devices with software 7.0(240.0) allow local users to execute arbitrary OS commands in a privileged context via crafted CLI commands.

The Wireless Intrusion Detection (WIDS) functionality on Cisco Wireless LAN Controller (WLC) devices allows remote attackers to cause a denial of service (device outage) via crafted packets that are improperly handled during rendering of the Signature Events Summary page.

Cisco Wireless LAN Controller (WLC) devices 7.2, 7.3, and 7.4 before 7.4.110.0 are vulnerable to an attack that can cause a denial of service by remotely sending a crafted 802.11 Ethernet frame, leading to a device restart.

Cisco Wireless LAN Controller (WLC) devices 7.2 before 7.2.115.2, 7.3, and 7.4 before 7.4.110.0 are vulnerable to an attack that can cause a denial of service through a crafted 802.11 Ethernet frame, leading to a device restart.

The multicast listener discovery (MLD) service on Cisco Wireless LAN Controller (WLC) devices in versions 7.2, 7.3, 7.4 before 7.4.121.0, and 7.5, when MLDv2 Snooping is enabled, allows remote attackers to cause a denial of service (device restart) via a malformed IPv6 MLDv2 packet.

Cisco Wireless LAN Controller (WLC) devices 7.4 before 7.4.110.0 have a race condition in the status of the administrative HTTP server, allowing remote attackers to bypass intended access restrictions.

Cisco Wireless LAN Controller (WLC) devices 7.0 before 7.0.250.0, 7.2, 7.3, and 7.4 before 7.4.110.0 do not properly deallocate memory, allowing remote attackers to cause a denial of service (reboot) by sending WebAuth login requests at a high rate.

Cisco Wireless LAN Controller (WLC) devices with software 7.6.x, 8.0 before 8.0.121.0, and 8.1 before 8.1.131.0 allow remote attackers to change configuration settings via unspecified vectors.
