CVE-2024-33865Network attack vector

NTLM hash disclosure via crafted API requests

Published May 14, 2024 · Updated Feb 13, 2025

Information disclosure in linqi before 1.4.0.1 on Windows allows remote attackers to obtain server NTLM hashes via crafted API requests. The /api/Cdn/GetFile and /api/DocumentTemplate/{GUID} endpoints accept a specially crafted request that causes an NTLM hash leak; linqi has not disclosed the lower-level input-handling error. Unauthenticated network access is sufficient, and the documented consequence is interception of server authentication hashes without data modification or service interruption.
