Core Mirth Connect

Security Improvements

An Unauthenticated Remote Command Execution vulnerability has been identified within Mirth Connect Core version 4.4.0 and lower. The XStream update discussed below was made to resolve this issue. Please refer to CVE-2023-43208 for more details on the vulnerability. https://nvd.nist.gov/vuln/detail/CVE-2023-43208

Switched XStream to Use Allowlist Instead of Denylist

Mirth Connect uses the XStream library to serialize and deserialize objects. It is a potential security risk to allow unexpected object types to be processed through XStream. Therefore we are now being more restrictive about what types are allowed by using an allowlist instead of a denylist. The only types allowed are those that are strictly necessary for Mirth Connect to operate. For details on how this may affect Mirth Connect when upgrading, see the upgrade guide.
