CVE-2026-9383Public exploitNetwork attack vector

Unauthenticated database access via username SQL injection

Published May 24, 2026 · Updated May 24, 2026

SQL injection in itsourcecode.com Electronic Judging System 1.0 allows remote attackers to access its MySQL database via the admin login. The /intrams/admin/login.php handler inserts the POST username parameter directly into an SQL query without sanitization or validation, allowing a time-based blind payload to alter query execution. No authentication or user interaction is required; the published proof of concept demonstrates database enumeration through the exposed login request.
