SQL Injection in SourceCodester Timetabling System Archive Function

A security flaw has been discovered in SourceCodester Class and Exam Timetabling System 1.0. This affects an unknown function of the file /archive4.php. The manipulation of the argument sy results in sql injection. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks.

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-2026-11483 represents a critical SQL injection vulnerability in SourceCodester Class and Exam Timetabling System version 1.0, specifically within the /archive4.php file's 'sy' parameter. With a CVSS score of 7.3, this high-severity flaw allows unauthenticated remote attackers to execute arbitrary SQL commands, potentially compromising database integrity, confidentiality, and availability. Educational institutions, training centers, and any organization using this timetabling system are at immediate risk. The public disclosure of an active exploit significantly escalates threat likelihood, making this vulnerability particularly dangerous for institutions that may have deployed this system without proper patching procedures.

Casky's 301 mapped skills leverage Claude AI's extended reasoning to detect the attack patterns underlying this vulnerability across MITRE ATT&CK techniques TA0001 (Initial Access) and TA0043 (Reconnaissance). Practitioners using Casky would identify SQL injection indicators through skills mapping CWE-74 and CWE-89, which flag suspicious parameter manipulation in web requests to /archive4.php, particularly payloads targeting the 'sy' parameter. The platform's detection capabilities would surface anomalous SQL syntax patterns, union-based query attempts, and time-based blind SQL injection signatures. Security teams would receive findings highlighting unauthorized database queries, unexpected schema enumeration attempts, and credential exfiltration patterns—enabling proactive threat hunting before data exfiltration occurs and allowing rapid containment of compromised instances.
