CVSS: 8.6EPSS: 0%CPEs: 6EXPL: 0CVE-2020-3273 – Cisco Wireless LAN Controller 802.11 Generic Advertisement Service Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3273
A vulnerability in the 802.11 Generic Advertisement Service (GAS) frame processing function of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS). The vulnerability is due to incomplete input validation of the 802.11 GAS frames that are processed by an affected device. An attacker could exploit this vulnerability by sending a crafted 802.11 GAS frame over the air to an access point (AP), and that frame would then be relayed to the affected WLC. Also, an attacker with Layer 3 connectivity to the WLC could exploit this vulnerability by sending a malicious 802.11 GAS payload in a Control and Provisioning of Wireless Access Points (CAPWAP) packet to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-gas-dos-8FsE3AWH • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 8.6EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3262 – Cisco Wireless LAN Controller CAPWAP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3262
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol handler of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to restart, resulting in a DoS condition.

CVSS: 8.6EPSS: 0%CPEs: 4EXPL: 0CVE-2019-15262 – Cisco Wireless LAN Controller Secure Shell Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-15262
A vulnerability in the Secure Shell (SSH) session management for Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability exists because the SSH process is not properly deleted when an SSH connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly opening SSH connections to an affected device. A successful exploit could allow the attacker to exhaust system resources by initiating multiple SSH connections to the device that are not effectively terminated, which could result in a DoS condition. Una vulnerabilidad en la gestión de sesión de Secure Shell (SSH) para Cisco Wireless LAN Controller (WLC) Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-wlc-ssh-dos • CWE-20: Improper Input Validation CWE-404: Improper Resource Shutdown or Release •
