An SQL Injection vulnerability exists in OpenMRS Reference Application Standalone Edition <=2.11 and Platform Standalone Edition <=2.4.0 via GET requests on arbitrary parameters in patient.page.

OpenMRS is a patient-based medical record system focusing on giving providers a free customizable electronic medical record system. Affected versions are subject to arbitrary file exfiltration due to failure to sanitize request when satisfying GET requests for `/images` & `/initfilter/scripts`. This can allow an attacker to access any file on a system running OpenMRS that is accessible to the user id OpenMRS is running under. Affected implementations should update to the latest patch version of OpenMRS Core for the minor version they use. These are: 2.1.5, 2.2.1, 2.3.5, 2.4.5 and 2.5.3. As a general rule, this vulnerability is already mitigated by Tomcat's URL normalization in Tomcat 7.0.28+. Users on older versions of Tomcat should consider upgrading their Tomcat instance as well as their OpenMRS instance.

In OpenMRS 2.9 and prior, the app parameter for the ActiveVisit's page is vulnerable to cross-site scripting.

In OpenMRS 2.9 and prior, the UI Framework Error Page reflects arbitrary, user-supplied input back to the browser, which can result in XSS. Any page that is able to trigger a UI Framework Error is susceptible to this issue.

In OpenMRS 2.9 and prior, the export functionality of the Data Exchange Module does not properly redirect to a login page when an unauthenticated user attempts to access it. This allows the export of potentially sensitive information.

OpenMRS 2.9 and prior copies "Referrer" header values into an html element named "redirectUrl" within many webpages (such as login.htm). There is insufficient validation for this parameter, which allows for the possibility of cross-site scripting.

In OpenMRS 2.9 and prior, the sessionLocation parameter for the login page is vulnerable to cross-site scripting.

In OpenMRS 2.9 and prior, he import functionality of the Data Exchange Module does not properly redirect to a login page when an unauthenticated user attempts to access it. This allows unauthenticated users to use a feature typically restricted to administrators.

OpenMRS openmrs-module-htmlformentry 3.3.2 is affected by: (Improper Input Validation).

OpenMRS before 2.24.0 is affected by an Insecure Object Deserialization vulnerability that allows an unauthenticated user to execute arbitrary commands on the targeted system via crafted XML data in a request body.
