A SQL injection vulnerability exists (with user privileges) in library/custom_template/ajax_code.php in OpenEMR 5.0.2.1.

A Stored XSS vulnerability in interface/usergroup/usergroup_admin.php in OpenEMR before 5.0.2.1 allows a admin authenticated user to inject arbitrary web script or HTML via the lname parameter.

The Patient Portal of OpenEMR 5.0.2.1 is affected by a incorrect access control system in portal/patient/_machine_config.php. To exploit the vulnerability, an unauthenticated attacker can register an account, bypassing the permission check of this portal's API. Then, the attacker can then manipulate and read data of every registered patient.

SQL injection vulnerability exists in phpGACL 3.3.7. A specially crafted HTTP request can lead to a SQL injection. An attacker can send an HTTP request to trigger this vulnerability in admin/edit_group.php, when the POST parameter action is “Submit”, the POST parameter parent_id leads to a SQL injection.

SQL injection vulnerabilities exist in phpGACL 3.3.7. A specially crafted HTTP request can lead to a SQL injection. An attacker can send an HTTP request to trigger this vulnerability In admin/edit_group.php, when the POST parameter action is “Delete”, the POST parameter delete_group leads to a SQL injection.

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, versions 4.2.0 to 6.0.0 are vulnerable to Reflected Cross-Site-Scripting (XSS) due to user input not being validated properly. An attacker could trick a user to click on a malicious url and execute malicious code.

In OpenEMR, versions 5.0.2 to 6.0.0 are vulnerable to Stored Cross-Site-Scripting (XSS) due to user input not being validated properly. A highly privileged attacker could inject arbitrary code into input fields when creating a new user.

In OpenEMR, versions 5.0.2 to 6.0.0 are vulnerable to Stored Cross-Site-Scripting (XSS) due to user input not being validated properly and rendered in the U2F USB Device authentication method page. A highly privileged attacker could inject arbitrary code into input fields when creating a new user.

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.
