A flaw was found in Moodle. When restricting access to a lesson activity with a password, certain passwords could be bypassed or less secure due to a loose comparison in the password-checking logic. This issue only affected passwords set to "magic hash" values.

According to its self-reported version, the Moodle install hosted on the remote host is 4.1.x prior to 4.1.13, 4.2.x prior to 4.2.10, 4.3.x prior to 4.3.7, or 4.4.x prior to 4.4.3. It is, therefore, affected by multiple vulnerabilities.

- A lesson activity password bypass through PHP loose comparison.

- An IDOR when deleting OAuth2 linked accounts.

- Unprotected access to sensitive information via dynamic tables.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
