In OpenEMR, versions 2.7.3-rc1 to 6.0.0 are vulnerable to Stored Cross-Site-Scripting (XSS) due to user input not being validated properly in the `Allergies` section. An attacker could lure an admin to enter a malicious payload and by that initiate the exploit.

In OpenEMR, versions v2.7.2-rc1 to 6.0.0 are vulnerable to Improper Access Control when creating a new user, which leads to a malicious user able to read and send sensitive messages on behalf of the victim user.

In OpenEMR 5.0.1 and earlier, an authenticated attacker can execute arbitrary commands on the host system via the Scanned Forms interface when creating a new form.

In OpenEMR 5.0.1 and earlier, the patient file download interface contains a directory traversal flaw that allows authenticated attackers to download arbitrary files from the host system.

In OpenEMR 5.0.1 and earlier, controller.php contains a reflected XSS vulnerability in the foreign_id parameter. This could allow an attacker to execute arbitrary code in the context of a user's session.

In OpenEMR 5.0.1 and earlier, controller.php contains a reflected XSS vulnerability in the document_id parameter. This could allow an attacker to execute arbitrary code in the context of a user's session.

In OpenEMR 5.0.1 and earlier, controller.php contains a reflected XSS vulnerability in the doc_id parameter. This could allow an attacker to execute arbitrary code in the context of a user's session.

In OpenEMR 5.0.1 and earlier, controller.php contains a reflected XSS vulnerability in the patient_id parameter. This could allow an attacker to execute arbitrary code in the context of a user's session.

An issue was discovered in custom/ajax_download.php in OpenEMR before 5.0.2 via the fileName parameter. An attacker can download any file (that is readable by the user www-data) from server storage. If the requested file is writable for the www-data user and the directory /var/www/openemr/sites/default/documents/cqm_qrda/ exists, it will be deleted from server.

OpenEMR before 5.0.2 allows SQL Injection in interface/forms/eye_mag/save.php.

An issue was discovered in OpenEMR before 5.0.1 Patch 7. SQL Injection exists in the SaveAudit function in /portal/lib/paylib.php and the portalAudit function in /portal/lib/appsql.class.php.

An issue was discovered in OpenEMR before 5.0.1 Patch 7. Directory Traversal exists via docid=../ to /portal/lib/download_template.php.

An issue was discovered in OpenEMR before 5.0.1 Patch 7. There is SQL Injection in the make_task function in /interface/forms/eye_mag/php/taskman_functions.php via /interface/forms/eye_mag/taskman.php.

A vulnerability in flashcanvas.swf in OpenEMR before 5.0.1 Patch 6 could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack on a targeted system.
