CVE-2025-43716Public exploitNetwork attack vector

Unauthenticated information disclosure via encoded URI suffix

Published Apr 23, 2025 · Updated Apr 23, 2025

Directory traversal in Ivanti LANDesk Management Gateway 4.2-1.9 and earlier allows remote attackers to access protected web endpoints. The /client/index.php endpoint validates the uncanonicalized URI, so an encoded question mark followed by .php changes path interpretation after the access-control check. No authentication or user interaction is required; a crafted request can disclose sensitive device details from the unsupported management panel.
