A recent security alert issued by the FDA and CISA has highlighted serious cybersecurity vulnerabilities in the Contec Health CMS8000 Patient Monitor, also known as Epsimed MN-120. These vulnerabilities may allow attackers to remotely control the device, compromise it through a backdoor, or exfiltrate sensitive patient data. Key flaws include an out-of-bounds write vulnerability, a hidden functionality backdoor, and privacy leakage risk. Immediate action is recommended for users of these devices, including their removal from networks. Affected: Contec Health CMS8000 Patient Monitor, Epsimed MN-120, medical devices sector
