SQL Injection in School Registration System Status Parameter

A vulnerability has been found in SourceCodester School Registration and Fee System 1.0. Impacted is an unknown function of the file /bilal/normal/save_stud.php. Such manipulation of the argument Status leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched 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-2026-90514 is a critical SQL injection vulnerability affecting SourceCodester School Registration and Fee System version 1.0, specifically in the /bilal/normal/save_stud.php endpoint where the Status parameter fails to properly sanitize user input before database queries. Educational institutions using this platform face direct risk of unauthorized database access, allowing attackers to exfiltrate sensitive student records, modify grades and enrollment data, or establish persistence within administrative systems. The public disclosure of this exploit significantly elevates risk, as attackers now have proven proof-of-concept code to target vulnerable installations at scale.

Casky's 323 matched skills leverage Claude AI's extended reasoning to detect the attack chain underlying this vulnerability across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance) by identifying indicators like malformed SQL syntax in Status parameter values, unusual database query patterns, and authentication bypass attempts. Practitioners using Casky would observe findings highlighting: (1) CWE-89 violation patterns showing unvalidated user input flowing directly into SQL queries, (2) suspicious parameter manipulation attempts in request logs, and (3) deviation from expected administrative workflows when attackers probe or exploit the save_stud.php endpoint. The platform maps these technical indicators to both initial access and information gathering phases, enabling security teams to prioritize remediation of input validation controls and implement web application firewalls blocking SQL injection payloads before they reach vulnerable code paths.
