CVE-2023-43208 Analysis
Healthcare providers that rely on NextGen HealthCare's open-source data integration cross-platform Mirth Connect solution are strongly recommended to instantly update the software to the latest version as a result of an instant disclosure of a novel RCE vulnerability tracked as CVE-2023-43208.
All Mirth Connect instances before version 4.4.1 are considered vulnerable to the revealed security bug. The vulnerability is a result of an incomplete patch of an earlier discovered RCE vulnerability impacting Mirth Connect v4.3.0 known as CVE-2023-37679 with a CVSS score of 9.8.
CVE-2023-43208 can be exploited by adversaries to gain initial access to the system, further leading to the compromise of critical healthcare data. On Windows systems, where Mirth Connect appears to be most commonly deployed and runs with the System privileges, CVE-2023-43208 can be weaponized by executing the ping command on a Windows host, as states the Horizon3.ai research. Although the exploit for CVE-2023-43208 is currently not publicly available, the exploitation methods based on Java XStream are widely recognized and well-documented. Cybersecurity researchers have refrained from sharing additional technical insights into the security bug due to the fact that even earlier Mirth Connect versions of 2015 and 2016 seem to be also at risk of compromise.
Due to the widespread knowledge of CVE-2023-43208 exploitation methods, it is strongly advised to update Mirth Connect to version 4.4.1 to minimize the risks, as well as proactively detect exploitation attempts. Stay ahead of any offensive campaigns with access to the latest detection algorithms from the Threat Detection Marketplace against CVEs, zero-days, and any emerging attacks of any scale.
