CVE-2022-36983Network attack vector

Unauthenticated configuration changes via exposed SetSettings function

Published Mar 29, 2023 · Updated Feb 18, 2025

Authentication bypass in Ivanti Avalanche 6.3.3.101 allows remote attackers to invoke SetSettings functionality without credentials. The SetSettings class exposes settings functionality without performing authentication before access is granted. Network reachability to the affected service is the only gate, and successful exploitation permits unauthorized configuration changes without data disclosure or service interruption.
