CVE-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 •
CVE-2022-20695 – Cisco Wireless LAN Controller Management Interface Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2022-20695
A vulnerability in the authentication functionality of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to bypass authentication controls and log in to the device through the management interface This vulnerability is due to the improper implementation of the password validation algorithm. An attacker could exploit this vulnerability by logging in to an affected device with crafted credentials. A successful exploit could allow the attacker to bypass authentication and log in to the device as an administrator. The attacker could obtain privileges that are the same level as an administrative user but it depends on the crafted credentials. Note: This vulnerability exists because of a non-default device configuration that must be present for it to be exploitable. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-auth-bypass-JRNhV4fF • CWE-287: Improper Authentication CWE-303: Incorrect Implementation of Authentication Algorithm •
CVE-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 •
