Title
Unauthenticated Denial-of-Service Vulnerability in HTTP Service in TP-Link TL-MR100, TL-MR150, TL-MR6400 and Archer MR600
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.

Title
Command Injection Vulnerability in Telnet CLI on TP-Link TL-MR6400
Summary
A command injection vulnerability has been identified in the Telnet command-line interface (CLI) of TP-Link TL-MR6400 v5.3. This issue is caused by insufficient sanitization of data processed during specific CLI operations. An authenticated attacker with elevated privileges may be able to execute arbitrary system commands. Successful exploitation may lead to full device compromise, including potential loss of confidentiality, integrity, and availability.
