Authenticated information disclosure through SMB requests
Published Apr 13, 2021 · Updated Aug 3, 2024
Information disclosure in Microsoft Windows SMB allows remote authenticated users to read sensitive information over the network. Public Microsoft and CNA records do not disclose the faulty operation; an IPS signature identifies the SMBv2 server SrvCreateBuildResponse path. A network-reachable SMB service and valid low-privilege credentials are required, and the reported impact is limited to confidentiality.
