Netgear RBK50 command injection

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

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.
