CVE-2023-43208
Unauthenticated Deserialization RCE in NextGen Healthcare Mirth Connect

CVE-2023-43208 is an unauthenticated remote code execution flaw in NextGen Healthcare Mirth Connect, a widely used healthcare integration engine, caused by incomplete patching of the earlier CVE-2023-37679 deserialization vulnerability. An attacker can trigger it by sending crafted serialized data to the network-exposed Mirth Connect service, requiring no authentication or user interaction (CVSS 3.1: 9.8, AV:N/AC:L/PR:N/UI:N). Successful exploitation yields arbitrary code execution on the server, giving attackers a foothold in hospital and health-system networks that Mirth Connect uses to move clinical data (including PHI) between systems. All deployments running Mirth Connect versions before 4.4.1 are affected. The flaw is being actively exploited — CISA added it to the Known Exploited Vulnerabilities catalog on 2024-05-20 with known ransomware use, public proof-of-concept exploits exist, and EPSS estimates an 82.7% chance of exploitation within 30 days.

Do: Upgrade Mirth Connect to version 4.4.1 or later as the CISA KEV required action, or discontinue use if upgrades are unavailable. Identify and restrict internet-exposed Mirth Connect instances (the service is commonly reachable on its web/admin interface), and hunt for signs of compromise given confirmed ransomware use. Because this bypasses the earlier CVE-2023-37679 fix, verify patch levels directly rather than assuming prior remediation.

An authentication bypass vulnerability was present in the GitHub Enterprise Server (GHES) when utilizing SAML single sign-on authentication with the optional encrypted assertions feature. This vulnerability allowed an attacker to forge a SAML response to provision and/or gain access to a user with site administrator privileges. Exploitation of this vulnerability would allow unauthorized access to the instance without requiring prior authentication. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.13.0 and was fixed in versions 3.9.15, 3.10.12, 3.11.10 and 3.12.4. This vulnerability was reported via the GitHub Bug Bounty program.

CVE-2024-5274
Google Chrome V8 Type Confusion Allows In-Sandbox RCE via Crafted HTML Pages

CVE-2024-5274 is a type confusion flaw (CWE-843) in the V8 JavaScript engine of Google Chrome prior to 125.0.6422.112. A remote attacker can trigger it by persuading a user to open or interact with a crafted HTML page. Successful exploitation allows the attacker to execute arbitrary code inside the browser's sandbox, and the scope-changed CVSS scoring indicates potential impact beyond the browser process itself. Anyone running an affected Chrome or Chromium build, including Chromium-derived distributions such as Fedora's Chromium package, is exposed. The flaw was added to CISA's KEV on 2024-05-28, a public PoC reference exists, and related news reports describe it as actively exploited in the wild.

Do: Upgrade Google Chrome to 125.0.6422.112 or later and confirm the build via chrome://version; Fedora users and users of Chromium-derived browsers should install the corresponding updated packages from their vendor. Because the flaw is listed in CISA KEV, federal agencies and targeted organizations must apply the vendor fix or discontinue use per the required action, and all users should avoid untrusted web content until patched.
