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.","2019-10-16",7.5,"v3.1","High",false,0.01415,{"cveId":26,"description":27,"publishedDate":11,"cvssScore":28,"cvssVersion":21,"severity":29,"isKev":23,"epssScore":30},"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.
