NTLMv2 hash disclosure via attacker-controlled UNC path
Published Mar 7, 2025 · Updated Mar 7, 2025
SMB forced authentication in Sage 200 Spain before 2025.35.000 allows remote authenticated users to capture an NTLMv2-SSP hash. An administrator can replace a configured path with a UNC path to an attacker-controlled SMB server, causing Sage 200 to send an NTLM authentication response. Administrative access to path settings is required, and the observed consequence is disclosure of the captured authentication hash.

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.
