SQL Injection in User Account Deletion Endpoint

A security vulnerability has been detected in SourceCodester Class and Exam Timetabling System 1.0. Affected by this vulnerability is an unknown functionality of the file /delete_user_account.php. Such manipulation of the argument ID leads to sql injection. The attack may be launched remotely. The exploit has been disclosed publicly 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-2026-86210 represents a critical SQL injection vulnerability in SourceCodester Class and Exam Timetabling System 1.0, specifically within the /delete_user_account.php file where unsanitized ID parameters are passed directly into SQL queries. This vulnerability carries a CVSS score of 7.3 (high) and affects any organization deploying this timetabling system, particularly educational institutions managing student and staff records. With public exploit disclosure and remote attack capability, the risk of compromise is elevated—adversaries can manipulate the ID argument to execute arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion of sensitive academic and administrative records.

Casky's 323 matched security skills leverage Claude AI's extended reasoning to identify attack patterns associated with MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance - data collection through vulnerability discovery). When analyzing this CVE, practitioners using Casky would observe detection patterns including: SQL query structure anomalies in application logs, unusual parameter encoding in HTTP requests to /delete_user_account.php, and database error messages leaking schema information—classic indicators of SQL injection attempts. The platform's skill mapping would highlight how adversaries progress from initial reconnaissance (identifying the vulnerable endpoint) through exploitation (crafting malicious SQL payloads), enabling security teams to implement preventive controls like parameterized queries, input validation, and WAF rules before attackers can operationalize this publicly disclosed weakness.
