Unauthenticated database access via unsanitized username

Published Nov 23, 2025 · Updated Feb 24, 2026

SQL injection in CampCodes Online Polling System in PHP/MySQL 1.0 allows remote attackers to access database data through the login form. The /admin/checklogin.php handler inserts the POST myusername value directly into a MySQL query without sanitization, validation, or parameter binding. No authentication is required; boolean-, error-, and time-based payloads can read sensitive database contents and alter or delete data.
