Security readout for executives and security teams
Plain-English summary
This Moodle issue could let a user export database activity entries from groups they should not see. The business risk is inappropriate disclosure of course or learner data where Moodle groups were used as an access boundary. The source bundle does not provide a CVSS score or evidence of active exploitation.
Executive priority
Treat this as a targeted confidentiality issue for legacy Moodle environments. Prioritize if Moodle stored sensitive learner or staff data in grouped database activities. It is not KEV-listed in the bundle and lacks severity scoring, so urgency should be driven by data sensitivity and affected version presence.
Technical view
CVE-2012-1155 affects Moodle 2.2.x, 2.1.x, 2.0.x, and 1.9.x. The database activity module export function reportedly exports all entries, including entries from groups outside the user's membership. This is an authorization scoping failure around export behavior, with confidentiality impact dependent on stored database activity content.
Likely exposure
Exposure is most likely in legacy Moodle deployments on 1.9.x through 2.2.x that use database activities with group separation. Risk is higher if entries contain student, staff, assessment, or operational data. The bundle does not identify other affected products.
Exploitation context
The provided sources do not cite CISA KEV listing or active exploitation. The issue appears reachable through normal Moodle database activity export functionality by a user with access to that feature, but the bundle does not provide exploit prerequisites beyond that description.
Researcher notes
Evidence is limited to the CVE description and advisory references. No CVSS, CWE, fixed version, or exploit status is provided in the bundle. Validate authorization scoping around database activity exports without relying on group membership as proof of isolation until patched or tested.
Mitigation direction
- Check Moodle and distribution advisories for fixed packages or upgrade guidance.
- Upgrade affected Moodle branches where vendor-supported fixes are available.
- Temporarily restrict database activity export permissions on affected deployments.
- Review database activities for sensitive entries separated only by Moodle groups.
- Prefer supported Moodle versions over legacy 1.9.x through 2.2.x branches.
Validation and detection
- Inventory Moodle versions and flag 1.9.x, 2.0.x, 2.1.x, and 2.2.x.
- Identify courses using the database activity module with group separation enabled.
- Review whether export permissions are granted to broad student or participant roles.
- In a controlled test, confirm exports are limited to the user's authorized group.
- Review Moodle logs for database activity exports involving sensitive courses.
