CWE-476

Description

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.

Affected configurations

• tp-link tl-mr100 firmware (< 1.3.0) • tp-link archer mr600 firmware (< 1.10.0) • tp-link tl-mr150 firmware (< 1.3.0) • tp-link tl-mr6400 firmware (< 1.5.0)
