SQL Injection in Online Reviewer Management System

A vulnerability was detected in SourceCodester Online Reviewer Management System 1.0. The impacted element is an unknown function of the file /reviewer_0/admins/assessments/subject/btn_functions.php?action=remove. Performing a manipulation of the argument ID results in sql injection. The attack can be initiated remotely. The exploit is now 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

SourceCodester's Online Reviewer Management System version 1.0 contains a critical SQL injection vulnerability in the assessment subject management function. The flaw exists in /reviewer_0/admins/assessments/subject/btn_functions.php where the 'ID' parameter passed to the 'remove' action is not properly sanitized before being used in database queries. This allows attackers to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion of assessment records and user credentials. Organizations deploying this system—particularly educational institutions and online learning platforms using SourceCodester's tools—face immediate risk of data breach and system compromise, especially since the exploit is now publicly disclosed.

Casky's 323 mapped skills leverage Claude's extended reasoning to correlate this vulnerability with MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance), detecting both initial exploitation patterns and post-compromise data gathering activities. Practitioners using Casky would identify SQL injection attack attempts through skills mapping CWE-74 and CWE-89, surfacing suspicious patterns such as SQL metacharacters in HTTP parameters, unusual database query structures in logs, and authentication bypass attempts targeting the btn_functions.php endpoint. The platform would flag reconnaissance activity where attackers probe the vulnerable parameter with test payloads, followed by data exfiltration queries—enabling teams to detect and respond to attacks before full system compromise occurs.
