TITLE

Cisco IOS  software and  Cisco IOS XE  Vulnerability of lack of releasing resources after valid lifetime in software

Trust: 0.8

sources: JVNDB: JVNDB-2022-009754

DESCRIPTION

A vulnerability in the web services interface of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper resource management in the HTTP server code. An attacker could exploit this vulnerability by sending a large number of HTTP requests to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition
