CVE-2025-65176Network attack vector

NTLM hash exposure via token impersonation

Published Dec 15, 2025 · Updated Dec 15, 2025

Improper access control in Dynatrace OneAgent before 1.325.47 allows remote attackers to expose NTLM hashes during network-share detection. After a remote share returns STATUS_LOGON_FAILURE, the Windows detection logic enumerates every local user token and retries access while impersonating each token. Exploitation requires control of the share interaction and enables captured NTLM authentication to be relayed to another service.
