Executive brief
itsourcecode Electronic Judging System is a web-based application used for managing and scoring competitions. A security vulnerability in the login page allows attackers to bypass security controls or access the underlying database by submitting specially crafted text in the username field. This could lead to the theft of sensitive competition data, unauthorized modification of scores, or a complete takeover of the system.
Technical details
A SQL injection vulnerability exists in itsourcecode Electronic Judging System 1.0 within the admin login component (/intrams/admin/login.php). The application fails to properly sanitize or validate the 'username' POST parameter before using it in a database query. A remote, unauthenticated attacker can exploit this by sending a crafted payload (such as time-based blind SQLi) to manipulate SQL queries. Successful exploitation can lead to unauthorized database access, data exfiltration, or authentication bypass. A public exploit (PoC) has been disclosed, and the vulnerability can be verified using automated tools like sqlmap.
