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.

CVE-2021-43298 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The HTTP digest authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. An unauthenticated remote attacker could bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel. CVE-2020-15688 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). An issue was discovered in Embedthis GoAhead 2.5.0. Certain pages (ex: goform/login and config/log_off_page.htm) create links containing a hostname obtained from an arbitrary HTTP host header sent by an attacker. This could potentially be used in a phishing attack. CVE-2019-16645 has been assigned to this vulnerability. A CVSS v3 base score of 8.6 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N). In http.c in Embedthis GoAhead before 4.1.1 and 5.x before 5.0.1, a header parsing vulnerability causes a memory assertion, out-of-bounds mem…
