CVE-2023-3059Public exploitNetwork attack vector

Authenticated database disclosure via unneutralized id parameter

Published Jun 2, 2023 · Updated Aug 2, 2024

SQL injection in SourceCodester Online Exam Form Submission 1.0 allows remote authenticated users to read database query results via the id parameter. The /admin/update_s6.php handler uses the GET id value in an SQL statement without neutralizing SQL syntax, enabling UNION-based and time-based blind injection. Administrative endpoint access is required; the demonstrated payloads return UNION results or delay responses, supporting database disclosure rather than host code execution.
