CVE-2021-45630 is a critical command injection vulnerability (CWE-77) affecting several NETGEAR devices, including specific versions of CBR40, CBR750, RBK/RBR/RBS750, and RBK/RBR/RBS850. This flaw allows an unauthenticated attacker to execute arbitrary commands, leading to complete compromise of the affected device. With a CVSS score of 9.8 (CRITICAL), it presents a severe risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Despite its high severity, there is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), and it has not been added to CISA's KEV catalog. Community discussion and media coverage for this CVE are also minimal, suggesting it is not widely known or actively exploited in the wild.
