Command Injection in NETGEAR R-Series and D-Series Routers cgi-bin Handler
CVE-2016-6277 is a remote command injection vulnerability affecting multiple NETGEAR routers, including R6250, R6400, R6700, R6900, R7000, R7100LG, R7300DST, R7900, R8000, D6220, D6400, and D7000, as well as possibly additional models. According to the provided content, affected firmware versions include R6250 before 1.0.4.6.Beta, R6400 before 1.0.1.18.Beta, R6700 before 1.0.1.14.Beta, R7000 before 1.0.7.6.Beta, R7100LG before 1.0.0.28.Beta, R7300DST before 1.0.0.46.Beta, R7900 before 1.0.1.8.Beta, and R8000 before 1.0.3.26.Beta, with R6900, D6220, D6400, D7000 also listed as affected in the source material. The flaw allows remote attackers to execute arbitrary shell commands by supplying shell metacharacters in PATH_INFO directed to the router's cgi-bin endpoint. This is consistent with OS command injection in a web-exposed CGI request handler, where unsanitized path data is incorporated into a shell command or shell-interpreted context.
