CVE-2019-12654 (GCVE-0-2019-12654)

Vulnerability from cvelistv5 – Published: 2019-09-25 20:16 – Updated: 2024-11-19 18:55

Title

Cisco IOS and IOS XE Software Session Initiation Protocol Denial of Service Vulnerability

Summary

A vulnerability in the common Session Initiation Protocol (SIP) library of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient sanity checks on an internal data structure. An attacker could exploit this vulnerability by sending a sequence of malicious SIP messages to an affected device. An exploit could allow the attacker to cause a NULL pointer dereference, resulting in a crash of the iosd process. This triggers a reload of the device.
