CVE-2025-4034Public exploitNetwork attack vector

Unauthenticated database access via unsanitized Doc_ID

Published Apr 28, 2025 · Updated Apr 28, 2025

SQL injection in Project Worlds Online Examination System 1.0 allows remote attackers to read or alter database data through Doc_ID. The inser_doc_process.php handler places the POSTed Doc_ID value directly into a MySQL query without validation, escaping, or parameter binding. No login or authorization is required, and the published proof of concept demonstrates boolean-, error-, and time-based database queries that can expose or modify stored data.
