Vulnerabilidades do NextGen Healthcare Mirth Connect

NextGen Connect (Mirth Connect) versions 4.7.1 and earlier allow an authenticated user to execute arbitrary SQL through a Database Connector API, which could result in disclosure of stored credentials for connected systems, arbitrary file write, and a denial-of-service condition.

When XML batch processing is turned on and the XPath option is selected, the raw batch input goes through a default XPath/JAXP setup with no entity restrictions, so XXE injection can allow data exfiltration and denial-of-service attacks.

The XSLT Transformer Step builds a bare TransformerFactory without the proper security options set, so XXE injection can allow data exfiltration and denial-of-service attacks.
