Description

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to 2.41.0, a flaw in the server-side authorization logic allowed authenticated users to perform actions beyond their assigned roles across multiple features. Because the affected endpoints relied on client-side or UI-level checks instead of enforcing permissions on the server, users with low-privileged roles (such as students) could perform operations intended only for instructors or administrators via directly using the API's. This vulnerability is fixed in 2.41.0.

Attack-Flow Graph

Executive Summary

This vulnerability in Frappe Learning Management System (LMS) prior to version 2.41.0 is due to a flaw in the server-side authorization logic. It allowed authenticated users with low-privileged roles, such as students, to perform actions beyond their assigned roles by bypassing client-side or UI-level permission checks and directly using the API. This means users could execute operations intended only for instructors or administrators.

Impact Analysis

The vulnerability can impact you by allowing users with low privileges to perform unauthorized actions within the LMS. This could lead to unauthorized access to sensitive content, modification of course materials, or administrative functions being performed by users who should not have such permissions, potentially compromising the integrity and security of the learning environment.

Mitigation Strategies

Upgrade the Frappe Learning Management System to version 2.41.0 or later, as this version contains the fix for the server-side authorization flaw that allowed low-privileged users to perform unauthorized actions.
