Credential-metadata disclosure via missing Guest authorization

Published Jan 31, 2020 · Updated May 30, 2025

Authorization failure in Zoho ManageEngine Remote Access Plus before 10.0.450 allows remote authenticated users to disclose credential metadata. The Credential Manager fails to deny Guest-role access to its credential listing, exposing names, types, usernames, domains or workgroups, and descriptions. A Guest account is required; stored passwords are not disclosed, but the exposed metadata covers all defined remote-machine credentials.
