NETGEAR has released security updates to address a remote code execution vulnerability—CVE-2021-40847—in multiple NETGEAR routers. A remote attacker could exploit this vulnerability to take control of an affected system.
CISA encourages users and administrators to review NETGEAR’s [Security Advisory](<https://kb.netgear.com/000064039/Security-Advisory-for-Remote-Code-Execution-on-Some-Routers-PSV-2021-0204 >) and update to the latest firmware. Given the increase in telework, CISA recommends that CISOs consider the risk that these vulnerabilities present to business networks. Review CISA’s Tip on [Home Network Security](<https://www.us-cert.gov/ncas/tips/ST15-002 >) for more information.
