Background

Moodle is an open-source learning management system (LMS) used by educational institutions to create and deliver online courses. It provides a platform for educators to manage course content, interact with students, and track their progress. Moodle is widely adopted and has a large user base. However, versions prior to 2.7.1 are vulnerable to an information disclosure issue.

Vulnerability Detail

The vulnerability in Moodle versions through 2.3.11, 2.4.x before 2.4.11, 2.5.x before 2.5.7, 2.6.x before 2.6.4, and 2.7.x before 2.7.1 allows remote attackers to obtain potentially sensitive username and course information. This is due to the lack of enforcement of certain capability requirements in the 'notes/index.php' and 'user/edit.php' files. Attackers can exploit this vulnerability by modifying the URL to access user and course information that should be restricted.

How To Fix

Fixed versions by release line

The minimum fixed version depends on the release line you run.

< 2.4.11 2.4.11
```
composer require moodle/moodle:2.4.11
```
>= 2.5.0, < 2.5.7 2.5.7
```
composer require moodle/moodle:2.5.7
```
>= 2.6.0, < 2.6.4 2.6.4
```
composer require moodle/moodle:2.6.4
```
>= 2.7.0, < 2.7.1 2.7.1
```
composer require moodle/moodle:2.7.1
```

Workaround

If upgrading to the latest version is not immediately feasible, a temporary workaround is to restrict access to the 'notes/index.php' and 'user/edit.php' files. This can be done by modifying the server configuration or implementing access control rules to block unauthorized access to these files.

Conclusion

The vulnerability in Moodle versions prior to 2.7.1 allows attackers to obtain sensitive username and course information. It is crucial to upgrade to the latest version or apply the recommended workaround to mitigate the risk. For further assistance and support in vulnerability remediation, please contact DevNack.com.
