Privilege Escalation via Incorrect Role Assignment in Masteriyo LMS

Incorrect Privilege Assignment vulnerability in ThemeGrill Masteriyo - LMS allows Privilege Escalation. This issue affects Masteriyo - LMS: from n/a through 2.2.0.

Casky was already ahead

This CVE exploits attack patterns that Casky's 203matched 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

Masteriyo - LMS versions through 2.2.0 contain an Incorrect Privilege Assignment vulnerability (CWE-266) that enables privilege escalation attacks. This flaw allows attackers to manipulate role and permission assignments, granting themselves elevated privileges within the learning management system. Organizations deploying Masteriyo for course delivery, student management, and educational content are directly at risk. An attacker exploiting this vulnerability could escalate from a low-privileged user account to administrator-level access, potentially compromising sensitive student data, course content, user credentials, and system integrity across the entire LMS infrastructure.

Casky's 203 mapped security skills leverage Claude AI with extended reasoning to detect privilege escalation attack patterns associated with TA0004 (Privilege Escalation) techniques. Practitioners using Casky would observe findings highlighting suspicious role modification events, unauthorized permission grants, and anomalous account privilege changes—particularly when standard users suddenly gain administrative capabilities without legitimate approval workflows. The platform's skill set would flag improper role assignment logic in authentication and authorization checks, detect inconsistencies between assigned and actual permissions, and identify exploitation attempts that bypass role-based access control (RBAC) mechanisms. Security teams would see detailed detection patterns specific to how attackers manipulate Masteriyo's privilege assignment functions to achieve lateral movement and persistence within their LMS environment.
