CVE-2022-4499

Estado: ModificadaAlta (7.5)—

TP-Link routers, Archer C5 and WR710N-V1, using the latest software, the strcmp function used for checking credentials in httpd, is susceptible to a side-channel attack. By measuring the response time of the httpd process, an attacker could guess each byte of the username and password.
