CVE-2020-25701: If the upload course tool in Moodle was used to delete an enrollment method which did not exist or was not...

If the upload course tool in Moodle was used to delete an enrollment method which did not exist or was not already enabled, the tool would erroneously enable that enrollment method. This could lead to unintended users gaining access to the course. Versions affected: 3.9 to 3.9.2, 3.8 to 3.8.5, 3.7 to 3.7.8, 3.5 to 3.5.14 and earlier unsupported versions. This is fixed in moodle 3.9.3, 3.8.6, 3.7.9, 3.5.15, and 3.10.

Security readout for executives and security teams

Plain-English summary

A Moodle course-upload workflow could accidentally turn on an enrollment method when trying to delete one that was absent or disabled. That could let unintended users access affected courses. The sources identify fixed Moodle releases, but provide no CVSS score or evidence of active exploitation.

Executive priority

Treat this as a moderate access governance issue. It is not presented as actively exploited, but it can expose private course material if affected Moodle versions and course-upload workflows are in use.

Technical view

CVE-2020-25701 is a CWE-284 access control issue in Moodle's upload course tool. For affected Moodle versions, a delete operation targeting a non-existent or disabled enrollment method could enable that method instead, changing course access behavior contrary to administrator intent.

Likely exposure

Exposure is likely limited to Moodle deployments running affected versions where the upload course tool is used to manage enrollment methods. Business impact depends on course sensitivity and which enrollment method becomes enabled.

Exploitation context

The provided sources do not state active exploitation, and KEV is false. They also do not provide public exploit details. The risky condition is operational misuse or crafted course-upload input affecting enrollment configuration.

Researcher notes

Evidence is limited to the CVE description and vendor/distribution references. No CVSS vector, exploit maturity detail, or technical patch analysis is included in the supplied bundle. Avoid assuming unauthenticated exploitation.

Mitigation direction

  • Upgrade Moodle to 3.9.3, 3.8.6, 3.7.9, 3.5.15, 3.10, or later.
  • Check Moodle and distribution advisories for environment-specific update guidance.
  • Review course enrollment methods after bulk course uploads or recent course-import changes.
  • Restrict access to the upload course tool to trusted administrators only.
  • Prioritize unsupported Moodle versions for upgrade or retirement.

Validation and detection

  • Inventory Moodle versions and identify any affected release branches.
  • Review courses for unexpectedly enabled enrollment methods.
  • Check administrative history around bulk course uploads or enrollment-method deletion attempts.
  • Confirm upgraded instances report a fixed Moodle version.
  • Validate that sensitive courses require the intended enrollment controls.
