The vulnerability in itsourcecode Electronic Judging System 1.0 arises from insufficient input validation of the num_id parameter in the /admin/edit_team.php script. This flaw permits remote attackers to perform SQL injection attacks by manipulating this parameter, potentially compromising the backend database. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and low to limited impact on confidentiality, integrity, and availability. No official remediation or patch has been provided by the vendor as of the publication date.

Successful exploitation could allow an attacker to execute arbitrary SQL commands on the database used by the Electronic Judging System, potentially leading to unauthorized data access or modification. However, the impact is rated medium due to limited confidentiality, integrity, and availability impacts as per the CVSS vector. There are no confirmed exploitations in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to the affected /admin/edit_team.php endpoint and apply web application firewall (WAF) rules to detect and block SQL injection attempts targeting the num_id parameter. Monitor vendor channels for updates or patches.
