CVE-2022-27646 is a critical vulnerability affecting NETGEAR R6700v3 1.0.4.120_10.0.91 routers, allowing network-adjacent attackers to execute arbitrary code. The flaw, a stack-based buffer overflow in the circled daemon, can be triggered by a crafted circleinfo.txt file, leading to root-level code execution. Despite requiring authentication, the existing mechanism can be bypassed. With a CVSS score of 8.8 (High), this vulnerability presents a significant risk due to its low attack complexity and high impact on confidentiality, integrity, and availability. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is it listed on the KEV catalog, and it has received minimal community discussion or media coverage.
