CVE-2023-43208
Overview
This vulnerability is a remote code execution flaw resulting from improper input validation in NextGen Healthcare Mirth Connect versions prior to 4.4.1. The root cause is an incomplete patch addressing a prior vulnerability, allowing injection of operating system commands via crafted HTTP requests. The affected component is the server API endpoints that process user-supplied data without adequate sanitization, enabling execution of arbitrary system commands.
Vulnerability Description
NextGen Healthcare Mirth Connect before version 4.4.1 is vulnerable to unauthenticated remote code execution. Note that this vulnerability is caused by the incomplete patch of CVE-2023-37679.
Impact
An unauthenticated attacker can execute arbitrary system commands on the vulnerable server, potentially gaining full control over the host environment. This enables unauthorized access to sensitive data, manipulation of system processes, and lateral movement within the network. No user interaction or credentials are required, making exploitation straightforward and allowing attackers to compromise the confidentiality, integrity, and availability of the affected system.
Solution
Upgrade NextGen Healthcare Mirth Connect to version 4.4.1 or later, where the incomplete patch has been fully applied to remediate this vulnerability. Refer to the vendor's official advisory and patch notes for detailed instructions. Additional mitigation includes monitoring and restricting access to the exposed API endpoints until the update is applied. Relevant references include the Horizon3 advisory and Packet Storm Security report for patch verification and implementation guidance.
