CVE-2023-41503Network attack vector

Unauthenticated SQL execution via crafted username

Published Mar 7, 2024 · Updated Apr 16, 2025

SQL injection in Code Projects Student Enrollment System 1.0 allows remote attackers to execute database commands through the login username. The Login function treats SQL syntax in the username field as part of a database query rather than neutralizing it as data. No account is required; a crafted username can expose or alter database data and defeat the login check.
