CVE-2023-39853Public exploitNetwork attack vector

Sensitive database disclosure via unsanitized query conditions

Published Jan 6, 2024 · Updated Jun 16, 2025

SQL injection in DzzOffice 2.01 allows remote authenticated users to read sensitive database data through the Network Disk backend. The filelist path places unfiltered doobj and do_obj request values into a condition array that fetch_all_event concatenates into SQL. A valid account is required, and exploitation exposes database information without reported data modification or service interruption.
