The U.S. Cybersecurity and Infrastructure Security Agency (CISA) recently added a significant security flaw impacting NextGen Healthcare Mirth Connect to its Known Exploited Vulnerabilities (KEV) catalog. This action underscores the critical nature of the vulnerability, which has already seen active exploitation in the wild. The flaw, identified as CVE-2023-43208, has a serious impact due to its unauthenticated remote code execution capabilities, stemming from an incomplete patch for a prior vulnerability (CVE-2023-37679), which scored 9.8 on the CVSS scale.
First reported by cybersecurity firm Horizon3.ai in October 2023, the vulnerability involves insecure usage of the Java XStream library for unmarshalling XML payloads, making it highly exploitable. Further technical details and a proof-of-concept (PoC) exploit were released in January 2024, prompting immediate attention from the cybersecurity community.
