About OpenMRS
---------------------------------------------------------------
OpenMRS is a software platform and a reference application which enables design of a customized medical records system with no programming knowledge (although medical and systems analysis knowledge is required). It is a common platform upon which medical informatics efforts in developing countries can be built. The system is based on a conceptual database structure which is not dependent on the actual types of medical information required to be collected or on particular data collection forms and so can be customized for different uses.

OpenMRS is now in use around the world (see the OpenMRS Atlas), including South Africa, Kenya, Rwanda, Lesotho, Zimbabwe, Mozambique, Uganda, Tanzania, Haiti, India, China, United States, Pakistan, the Phillipines, and many other places. This work is supported in part by many organizations including international and government aid groups, NGO’s, aswell as for-profit and non-profit corporations.

Multiple Persistent and Reflected Cross-Site Scripting (CVE-2014-8071)
----------------------------------------------------------------------
Persistent XSS

Parameters that are displayed back to the user are mostly vulnerable to cross-site scripting as user input was not validate properly and as a result, the malicious script was stored by the application and executed when it was displayed back to the user.

Below are several examples on the persistent and reflected XSS identified in OpenMRS 2.1 Standalone
