Lifecycle Timeline
2DescriptionGitHub Advisory
OpenEMR is a free and open source electronic health records and medical practice management application. A Broken Access Control vulnerability in OpenEMR up to and including version 8.0.0.3 allows low-privilege users to view and download Ensora eRx error logs without proper authorization checks. This flaw compromises system confidentiality by exposing sensitive information, potentially leading to unauthorized data disclosure and misuse. As of time of publication, no known patches versions are available.
AnalysisAI
Low-privilege authenticated users in OpenEMR versions up to and including 8.0.0.3 can view and download Ensora eRx error logs due to missing authorization checks, exposing sensitive healthcare system information. This broken access control vulnerability (CVSS 7.7) affects network-accessible installations and has a 3% EPSS exploitation probability (8th percentile), with no public exploit identified at time of analysis. No vendor-released patch identified at time of analysis according to the CVE disclosure.
Technical ContextAI
OpenEMR is an open-source electronic health records and medical practice management system widely deployed in healthcare environments. The vulnerability stems from CWE-285 (Improper Authorization), where the application fails to implement proper access control checks on endpoints serving Ensora eRx error logs. The affected product is identified via CPE cpe:2.3:a:openemr:openemr:*:*:*:*:*:*:*:* covering all versions through 8.0.0.3. The flaw allows privilege escalation within the application context, enabling low-privilege users to access administrative or system-level log files containing potentially sensitive healthcare transaction data, prescription information, and system configuration details that should be restricted to higher-privilege roles.
RemediationAI
No vendor-released patch identified at time of analysis according to the CVE disclosure statement. Organizations should monitor the OpenEMR security advisory at https://github.com/openemr/openemr/security/advisories/GHSA-6qg7-6jf3-xrfh for patch release announcements and apply updates immediately when available. Until patching is possible, implement compensating controls including strict user privilege review to ensure only necessary accounts have low-level access, enable comprehensive access logging for Ensora eRx error log endpoints to detect unauthorized viewing attempts, restrict network access to the OpenEMR instance to trusted IP ranges via firewall rules or VPN, and consider temporarily disabling Ensora eRx error log access features if operationally feasible. Review existing user accounts for evidence of unauthorized log access during the vulnerable period.
