What it is

An

unauthenticated denial-of-service vulnerability was identified in TP-Link TL-MR100 v3.2, TL-MR150 v3.2, TL-MR6400 v8.0 and Archer MR600 v2, due to improper handling of exceptional request conditions

that may lead to a NULL pointer dereference.

A remote attacker on an adjacent network can send a specially crated

HTTP request to trigger a crash of the HTTP service process.

Successful

exploitation may cause the HTTP service to crash, making the web management

interface and HTTP-dependent functionality temporarily unavailable.
