CVE-2023-45111Network attack vector

Unauthenticated SQL injection via feed.php email

Published Nov 2, 2023 · Updated Sep 5, 2024

SQL injection in Online Examination System 1.0 allows remote attackers to alter database queries through the feed.php email parameter. The feed.php endpoint sends the email value directly to database processing without validating or neutralizing SQL metacharacters. No authentication or user interaction is required, so a network attacker can read or modify database data and disrupt service.
