CVE-2024-8601Network attack vector

Cross-account data disclosure via user-controlled API parameter

Published Sep 9, 2024 · Updated Sep 9, 2024

Authorization bypass in TechExcel Back Office Software before 1.0.0 allows remote authenticated users to read sensitive data from other users. Certain API endpoints use a request-URL parameter to select user records without enforcing object-level authorization. A valid account is required, and the documented consequence is cross-account data disclosure without reported data modification or service interruption.
