SQL Injection in Class and Exam Timetabling System

A vulnerability was detected in SourceCodester Class and Exam Timetabling System 1.0. Affected by this vulnerability is an unknown functionality of the file /archive1.php. Performing a manipulation of the argument sy results in sql injection. Remote exploitation of the attack is possible. The exploit is now public and may 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-2026-11486 is a critical SQL injection vulnerability affecting SourceCodester Class and Exam Timetabling System version 1.0, specifically in the /archive1.php file where the 'sy' parameter is improperly sanitized. This flaw allows remote attackers to execute arbitrary SQL commands 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 student data, exam schedules, and institutional information could be compromised. With public exploits now available and no current CISA KEV listing, organizations should prioritize patching before threat actors actively weaponize this vulnerability at scale.

Casky's 301 mapped security skills leverage Claude AI's extended reasoning to detect the attack patterns underlying this CVE across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance). Practitioners using Casky would observe detections for SQL injection attack signatures (CWE-89), parameter manipulation attempts, and suspicious database query patterns in /archive1.php logs. The platform's skills would flag anomalous 'sy' parameter values, detect escaped SQL syntax in request payloads, and identify unauthorized database access attempts. By correlating these indicators with reconnaissance activities, practitioners gain visibility into pre-exploitation probing, allowing them to harden input validation, implement Web Application Firewalls (WAF) rules, and establish database query monitoring before attackers escalate from reconnaissance to exploitation.
