OpenEMR Local File Include and Cross-Site Scripting Vulnerabilities

OpenEMR is prone to a local file-include vulnerability and multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.

An attacker can exploit the local file-include vulnerability using directory-traversal strings to view and execute local files within the context of the affected application. Information harvested may aid in further attacks.
The attacker may leverage the cross-site scripting issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.
