SQL Injection in Class and Exam Timetabling System

A vulnerability was identified in SourceCodester Class and Exam Timetabling System 1.0. The impacted element is an unknown function of the file /archive5.php. The manipulation of the argument sy leads to sql injection. The attack can be initiated remotely. The exploit is publicly available and might be used.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — 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-2026-11482 exposes a critical SQL injection vulnerability in SourceCodester's Class and Exam Timetabling System version 1.0, specifically through the /archive5.php endpoint's 'sy' parameter. With a CVSS score of 7.3, this high-severity flaw allows remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion of sensitive academic records. Educational institutions using this timetabling system face immediate risk, as attackers can exploit this publicly available exploit to compromise student information, class schedules, and examination data—critical assets for any academic environment.

Casky's 301 matched security skills detect the attack patterns mapped to MITRE ATT&CK techniques TA0001 (Initial Access) and TA0043 (Reconnaissance) by analyzing input validation failures and SQL query construction anomalies. When practitioners run Claude AI's extended reasoning across Casky's skill library, they'll identify characteristic indicators: suspicious parameter manipulation in HTTP requests to /archive5.php, malformed SQL syntax in application logs, and database error messages revealing backend query structures. The platform surfaces CWE-74 (Improper Neutralization of Special Elements in Output) and CWE-89 (SQL Injection) violations, enabling security teams to detect both reconnaissance attempts probing for injection points and actual exploitation attempts that bypass input sanitization controls.
