Unauthenticated information disclosure via unvalidated URI fetch

Published Dec 19, 2023 · Updated Aug 2, 2024

SSRF in Ivanti Avalanche Remote Control Server 6.4.1 and earlier allows remote attackers to disclose sensitive information via crafted web requests. The validateAMCWSConnection method accesses attacker-supplied URIs without properly validating them before retrieving resources. No authentication or user interaction is required; requests execute under SYSTEM and expose information reachable from the server.
