CVE-2022-20692 (GCVE-0-2022-20692)

Vulnerability from cvelistv5 – Published: 2022-04-15 14:16 – Updated: 2024-11-06 16:26

Summary

A vulnerability in the NETCONF over SSH feature of Cisco IOS XE Software could allow a low-privileged, authenticated, remote attacker to cause a denial of service condition (DoS) on an affected device. This vulnerability is due to insufficient resource management. An attacker could exploit this vulnerability by initiating a large number of NETCONF over SSH connections. A successful exploit could allow the attacker to exhaust resources, causing the device to reload and resulting in a DoS condition on an affected device.
