Details
A vulnerability classified as critical has been found in Netgear EX6200v2, EX6250, EX7700, EX8000, LBR1020, LBR20, R7800, R8900, R9000, RBS50Y, WNR2000v5, XR700, EX6150v2, EX7300, EX7320, RAX10, RAX120, RAX70, EX6100v2, EX6400, EX7300v2, R6700AX, RAX120v2, RAX78, EX6410, RBR10, RBR20, RBR350, RBR40, RBR50, EX6420, RBS10, RBS20, RBS350, RBS40, RBS50, EX6400v2, RBK12, RBK20, RBK352, RBK40 and RBK50 (Wireless LAN Software). This affects an unknown code block. 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. This is going to have an impact on confidentiality, integrity, and availability.
