CVSS: 7.4EPSS: 0%CPEs: 8EXPL: 0CVE-2022-20769 – Cisco Wireless LAN Controller AireOS Software FIPS Mode Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20769
A vulnerability in the authentication functionality of Cisco Wireless LAN Controller (WLC) AireOS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error validation. An attacker could exploit this vulnerability by sending crafted packets to an affected device. A successful exploit could allow the attacker to cause the wireless LAN controller to crash, resulting in a DoS condition. Note: This vulnerability affects only devices that have Federal Information Processing Standards (FIPS) mode enabled. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-dos-mKGRrsCB • CWE-787: Out-of-bounds Write •
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 •

https://notcve.org/view.php?id=CVE-2017-3854
A vulnerability in the mesh code of Cisco Wireless LAN Controller (WLC) software could allow an unauthenticated, remote attacker to impersonate a WLC in a meshed topology. The vulnerability is due to insufficient authentication of the parent access point in a mesh configuration. An attacker could exploit this vulnerability by forcing the target system to disconnect from the correct parent access point and reconnect to a rogue access point owned by the attacker. An exploit could allow the attacker to control the traffic flowing through the impacted access point or take full control of the target system. This vulnerability affects the following products running a vulnerable version of Wireless LAN Controller software and configured for meshed mode: Cisco 8500 Series Wireless Controller, Cisco 5500 Series Wireless Controller, Cisco 2500 Series Wireless Controller, Cisco Flex 7500 Series Wireless Controller, Cisco Virtual Wireless Controller, Wireless Services Module 2 (WiSM2). • http://www.securityfocus.com/bid/96911 http://www.securitytracker.com/id/1038041 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170315-wlc-mesh • CWE-287: Improper Authentication •
