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.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Netgear CBR40, CBR750, EAX20, EAX80, EX7500, LAX20, MK62, MR60, MS60, R6400v2, R6700v3, R6900P, R7000, R7000P, R7850, R7900, R7900P, R7960P, R8000, R8000P, RAX15, RAX20, RAX200, RAX35v2, RAX40v2, RAX43, RAX45, RAX50, RAX75, RAX80, RBK752, RBK852, RBR750, RBR850, RBS750, RBS850, RS400, XR1000 and XR300 (Router Operating System). Affected by this issue is an unknown code block. The manipulation with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability.
