"According to its self-reported version, the instance of NextGen Mirth Connect running on the remote web server is
prior to 4.7.2. It is, therefore, affected by multiple vulnerabilities:

  - 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. (CVE-2026-82583)

  - 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. (CVE-2026-78224)

  - 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. (CVE-2026-82578)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
