Privilege Escalation via Role Parameter Manipulation in Registration

A flaw has been found in SourceCodester Onlne Examination & Learning Management System 1.0. The impacted element is an unknown function of the file register.php of the component Registration Endpoint. Executing a manipulation of the argument role can lead to improper privilege management. The attack can be executed remotely. The exploit has been published and may be used. The name of the affected product appears to have a typo in it.

Casky was already ahead

This CVE exploits attack patterns that Casky's 224matched 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

This vulnerability in SourceCodester Online Examination & Learning Management System 1.0 allows unauthenticated attackers to manipulate user roles during registration through the register.php endpoint. By modifying the 'role' parameter, attackers can escalate their privileges to administrative or instructor accounts without proper authorization. This impacts any organization deploying this LMS for educational or training purposes, potentially affecting student data integrity, course content security, and institutional systems. The remote exploitability and published proof-of-concept increase the urgency for patching across affected deployments.

Casky's 224 mapped security skills detect this attack pattern by identifying the core MITRE ATT&CK technique TA0004 (Privilege Escalation) through Claude AI's extended reasoning capabilities. Practitioners using Casky would observe detections aligned with CWE-266 (Improper Privilege Management) and CWE-269 (Improper Access Control) patterns—specifically unvalidated parameter manipulation during authentication flows. The platform's skill set would flag suspicious registration requests where role assignments deviate from expected values, insufficient input validation on privilege-related parameters, and authentication logic that fails to enforce proper role constraints. Security teams would see findings highlighting the absence of server-side role validation, client-side role assignment opportunities, and the lack of authorization checks between user input and granted permissions.
