Vulnerabilidades do Openemr Openemr

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, a Broken Access Control vulnerability exists in OpenEMR’s edih_main.php endpoint, which allows any authenticated user—including low-privilege roles like Receptionist—to access EDI log files by manipulating the log_select parameter in a GET request. The back-end fails to enforce role-based access control (RBAC), allowing sensitive system logs to be accessed outside the GUI-enforced permission boundaries. Version 8.0.0 fixes the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 7.0.4, the `disposeDocument()` method in `EtherFaxActions.php` allows authenticated users to read arbitrary files from the server filesystem. Any authenticated user (regardless of privilege level) can exploit this vulnerability to read sensitive files. Version 7.0.4 patches the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the Eye Exam form module allows any authenticated user to be redirected to an arbitrary external URL. This can be exploited for phishing attacks against healthcare providers using OpenEMR. Version 8.0.0 fixes the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the `xl()` translation function returns unescaped strings. While wrapper functions exist for escaping in different contexts (`xlt()` for HTML, `xla()` for attributes, `xlj()` for JavaScript), there are places in the codebase where `xl()` output is used directly without escaping. If an attacker could insert malicious content into the translation database, these unescaped outputs could lead to XSS. Version 8.0.0 fixes the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, a stored cross-site scripting vulnerability in the GAD-7 anxiety assessment form allows authenticated users with clinician privileges to inject malicious JavaScript that executes when other users view the form. This enables session hijacking, account takeover, and privilege escalation from clinician to administrator. Version 8.0.0 fixes the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 7.0.4, when a link is sent via Secure Messaging, clicking the link opens the website within the OpenEMR/Portal site. This behavior could be exploited for phishing. Version 7.0.4 patches the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Versions 5.0.0.5 through 7.0.3.4 have a stored cross-site scripting vulnerability in the ub04 helper of the billing interface. The variable `$data` is passed in a click event handler enclosed in single quotes without proper sanitization. Thus, despite `json_encode` a malicious user can still inject a payload such as ` ac' ><img src=x onerror=alert(document.cookie)> ` to trigger the bug. This vulnerability allows low privileged users to embed malicious JS payloads on the server and perform stored XSS attack. This, in turn makes it possible for malicious users to steal the session cookies and perform unauthorized actions impersonating administrators. Version 7.0.4 patches the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 7.0.4 have a vulnerability where sensitive data is unintentionally revealed to unauthorized parties. Contents of Clinical Notes and Care Plan, where an encounter has Sensitivity=high, can be viewed and changed by users who do not have Sensitivities=high privilege. Version 7.0.4 fixes the issue.

OpenEMR 5.0.2.1 contains a cross-site scripting vulnerability in user profile parameters that authenticated attackers can chain with a file upload to achieve remote code execution. Attackers can exploit the vulnerability by crafting a malicious payload to download and execute a web shell, enabling remote command execution on the vulnerable OpenEMR instance.
