Executive Summary

This vulnerability affects OpenEMR versions before 8.5.0 due to missing authorization checks in portal/import_template.php. Authenticated staff users can exploit unguarded modes to delete template profiles, read template contents, or push templates to patients without proper permissions.

Detection Guidance

Check OpenEMR version with: grep -r "openemr" /var/www/html/openemr/version.php or check the admin dashboard. Inspect portal/import_template.php for unauthorized modes like save_profiles, get, or getPdf. Monitor logs for suspicious template modifications or deletions.

Impact Analysis

An attacker could delete all document-template profiles, expose sensitive template contents, or manipulate patient template associations. This could disrupt medical record management, leak confidential data, or alter patient records without authorization.

Compliance Impact

This vulnerability likely violates HIPAA due to unauthorized access to patient data and integrity breaches. GDPR compliance may also be impacted if personal data is exposed or mishandled. Organizations must mitigate this to maintain regulatory adherence.

Mitigation Strategies

Upgrade OpenEMR to version 8.5.0 or later immediately. If upgrading is not possible, restrict access to portal/import_template.php via web server rules and disable untrusted staff user access until patched.
