Detailsinfo

A vulnerability, which was classified as critical, was found in NETGEAR RS700, RAX54Sv2, RAX41v2, RAX50, RAXE500, RAX41, RAX43, RAX35v2, RAXE450, RAX43v2, RAX42, RAX45, RAX50v2, MR90, RAX42v2, RAX49S and MS90. This affects an unknown functionality of the component DNS Response Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the speedtest feature of affected NETGEAR Nighthawk routers, caused by improper input validation, can allow attackers on the router's WAN side, using attacker-in-the-middle techniques (MiTM) to manipulate DNS responses and execute commands when speedtests are run. This issue affects RS700: through 1.0.7.82; RAX54Sv2 : before V1.1.6.36; RAX41v2: before V1.1.6.36; RAX50: before V1.2.14.114; RAXE500: before V1.2.14.114; RAX41: before V1.0.17.142; RAX43: before V1.0.17.142; RAX35v2: before V1.0.17.142; RAXE450: before V1.2.14.114; RAX43v2: before V1.1.6.36; RAX42: before V1.0.17.142; RAX45: before V1.0.17.142; RAX50v2: before V1.1.6.36; MR90: before V1.0.2.46; MS90: before V1.0.2.46; RAX42v2: before V1.1.6.36; RAX49S: before V1.1.6.36.
