CVE-2019-12647 (GCVE-0-2019-12647)

Vulnerability from cvelistv5 – Published: 2019-09-25 20:05 – Updated: 2024-11-19 18:56

Title

Cisco IOS and IOS XE Software IP Ident Denial of Service Vulnerability

Summary

A vulnerability in the Ident protocol handler of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability exists because the affected software incorrectly handles memory structures, leading to a NULL pointer dereference. An attacker could exploit this vulnerability by opening a TCP connection to specific ports and sending traffic over that connection. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.
