Unauthenticated server host-name disclosure

Published Sep 8, 2023 · Updated Sep 26, 2024

Information disclosure in HCL Domino 12.0.2 and 12.0.2FP1 allows remote attackers to obtain the server host name via network requests. HCL Software has not published the request path, response field, code locus, or configuration setting responsible for returning the host name. Exposure requires an unspecified configuration scenario and is limited to host-name disclosure useful for targeting later attacks, with no reported data modification or service interruption.
