Authenticated cross-employee data overwrite via IDOR
Published Aug 9, 2021 · Updated Sep 17, 2024
Insecure direct object reference in Larvata Digital Technology Co. Ltd. FLYGO through 2021.4e allows remote authenticated users to overwrite another employee's data via an API employee ID. The employee management page accepts a caller-supplied employee identifier without enforcing object-level authorization, allowing a general user to target another employee's record. Exploitation requires a valid general-user account and network access; the documented consequence is unauthorized integrity modification, not service interruption.
