CVE-2021-43298

The code that performs password matching when using 'Basic' HTTP authentication does not use a constant-time memcmp and has no rate-limiting. This means that an unauthenticated network attacker can brute-force the HTTP basic password, byte-by-byte, by recording the webserver's response time until the unauthorized (401) response.

El código que lleva a cabo la coincidencia de contraseñas cuando es usada la autenticación HTTP "Basic" no usa un memcmp de tiempo constante y no presenta limitación de velocidad. Esto significa que un atacante de red no autenticado puede forzar la contraseña básica HTTP, byte a byte, registrando el tiempo de respuesta del servidor web hasta la respuesta no autorizada (401)
