SQL Injection in Electronic Judging System Login

A vulnerability was identified in itsourcecode Electronic Judging System 1.0. This affects an unknown part of the file /intrams/login.php. Such manipulation of the argument Username leads to sql injection. The attack can be launched remotely. The exploit is publicly available and might be used.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills have been training on — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-7555 is a critical SQL injection vulnerability affecting itsourcecode Electronic Judging System 1.0, specifically in the login authentication mechanism at /intrams/login.php. The vulnerability exists because user-supplied input in the Username parameter is not properly sanitized before being used in SQL queries, allowing attackers to manipulate database operations remotely. Educational institutions and organizations using this judging system are at immediate risk, as the exploit is publicly available and requires no special privileges—an attacker can gain unauthorized access, extract sensitive data, or modify system records simply by submitting malicious SQL commands through the login form.

Casky's 301 matched skills leverage Claude AI's extended reasoning to correlate this vulnerability with MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance - specifically gathering information about target systems). When practitioners run detection rules against their environment, they would identify suspicious SQL syntax patterns in login attempts (such as SQL comments, boolean conditions, or UNION-based queries in the Username field), authentication bypass attempts that succeed without valid credentials, and unusual database query patterns in application logs. The platform maps these behavioral indicators to SQL injection attack chains, helping security teams recognize both initial reconnaissance probing and active exploitation attempts, enabling faster incident response and vulnerability remediation before attackers establish persistence or exfiltrate data.
