Vulnerability from variot
A vulnerability in the web server authentication of Cisco IOS XE Software could allow an authenticated, remote attacker to crash the web server on the device. The vulnerability is due to insufficient input validation during authentication. An attacker could exploit this vulnerability by entering unexpected characters during a valid authentication. A successful exploit could allow the attacker to crash the web server on the device, which must be manually recovered by disabling and re-enabling the web server. Cisco IOS XE The software contains an input validation vulnerability.Service operation interruption (DoS) It may be in a state. Both Cisco IOS and IOS XE are a set of operating systems developed by Cisco for its network equipment
