files/externallib.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 does not consider the moodle/user:manageownfiles capability before approving a private-file upload, which allows remote authenticated users to bypass intended file-management restrictions by using web services to perform uploads after this capability has been revoked.

Security readout for executives and security teams

CVE-2015-3181 lets an authenticated Moodle user upload private files through web services even after administrators revoke that user’s own-file management permission. This is a permissions bypass, not a documented system takeover. Business impact depends on whether affected Moodle versions and web services remain in use. Exposure is likely limited to Moodle deployments running affected legacy versions with web services reachable by authenticated users. Environments relying on revoked moodle/user:manageownfiles permissions are most directly impacted. Treat this as a targeted cleanup item for legacy Moodle systems. Prioritize if Moodle stores sensitive learner, staff, or customer files, or if web services are exposed to broad authenticated populations. Mitigation focus: Upgrade Moodle 2.6.x to 2.6.11 or later.; Upgrade Moodle 2.7.x to 2.7.8 or later.; Upgrade Moodle 2.8.x to 2.8.6 or later..
