CVE-2024-22052Network attack vector

Service crash via IPSec null pointer dereference

Published Apr 4, 2024 · Updated Oct 3, 2024

Null pointer dereference in the IPSec component of Ivanti Connect Secure 9.x and 22.x and Policy Secure allows remote attackers to crash the service. Ivanti has not published the affected function, request field, or invalid state that causes the IPSec component to dereference a null pointer. No authentication or user interaction is required, and a crafted network request interrupts the IPSec service without reported confidentiality or integrity impact.
