NTLM hash disclosure via attacker-controlled path
Published Mar 11, 2025 · Updated Feb 13, 2026
Windows NTLM in affected Microsoft Windows builds allows remote attackers to disclose NTLM hashes through an attacker-controlled path. Microsoft has not published the concrete path format, affected function, or file-system operation that initiates authentication to the remote endpoint. Exploitation requires user interaction, and the reported consequence is credential-material disclosure rather than direct code execution or system modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
