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 •
