Description
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.
