Sensitive log disclosure via missing authorization

Published Oct 13, 2023 · Updated Sep 18, 2024

IDOR in GRANDING UTime Master 9.0.7-Build:Apr 4,2023 allows remote authenticated users to read sensitive administrator logs. The /base/adminlog/table/ endpoint returns administrator-only logs for any valid session cookie instead of enforcing administrator authorization. Any application account is sufficient, and the exposed logs include employee attendance passwords, limiting the demonstrated impact to unauthorized disclosure.
