CVE-2019-19505

Estado: ModificadaAlta (8.8)—

Tenda PA6 Wi-Fi Powerline extender 1.0.1.21 is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the "Wireless" section in the web-UI. By sending a specially crafted hostname, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
