CVE-2024-7921Public exploitNetwork attack vector

Authenticated parking-record disclosure via GetDataList authorization failure

Published Aug 19, 2024 · Updated Aug 19, 2024

Improper access control in JieLink+ JSOTC2016 20240805 and earlier allows remote authenticated users to read parking exit records. The /report/ParkOutRecord/GetDataList endpoint applies inadequate authorization to crafted requests, although public sources do not disclose its parameters or implementation. A low-privileged network account is required, and the CNA assessment limits the demonstrated impact to disclosure without data modification or service interruption.
