Description

A vulnerability exists within Mirth Connect due to its mishandling of deserialized data. This vulnerability can be leveraged by an attacker using a crafted HTTP request to execute OS commands within the context of the target application. The original vulnerability was identified by IHTeam and assigned CVE-2023-37679. Later, researchers from Horizon3.ai determined the patch to be incomplete and published a gadget chain which bypassed the deny list that the original had implemented. This second vulnerability was assigned CVE-2023-43208 and was patched in Mirth Connect version 4.4.1. This module has been tested on versions 4.1.1, 4.3.0 and 4.4.0.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
