Background
Moodle is an open-source learning management system (LMS) used by educational institutions to create and manage online courses. It provides a platform for educators to deliver content, engage with students, and assess their progress. Moodle allows users to upload and store files, including private files that are only accessible to the user who uploaded them. These private files can contain sensitive information such as personal documents or confidential data. However, a vulnerability in Moodle versions before 2.2.2 allowed course backups to include users' private files, resulting in an information disclosure risk.
Vulnerability Detail
The vulnerability in Moodle versions before 2.2.2 allowed course backups to include users' private files. This means that when a course backup was created, it would also include any private files uploaded by users enrolled in the course. This information disclosure could lead to the exposure of sensitive data, such as personal documents or confidential information. The vulnerability was classified as moderate severity with a CVSS score of 4.3.
