Summary
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.
