Detailsinfo

A vulnerability classified as critical has been found in Netgear D6400, EX6200, EX7000, R6250, R6300v2, R6400, R6700, R7000, R7100LG, R7300DST, R7900, R8000, R8300, R8500, WNDR3400v3 and WNR3500Lv2 (Wireless LAN Software). Affected is some unknown functionality. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
