websda.c in GoAhead WebServer 2.1.8 has insufficient nonce entropy because the nonce calculation relies on the hardcoded onceuponatimeinparadise value, which does not follow the secret-data guideline for HTTP Digest Access Authentication in RFC 7616 section 3.3 (or RFC 2617 section 3.2.1). NOTE: 2.1.8 is a version from 2003; however, the affected websda.c code appears in multiple derivative works that may be used in 2021. Recent GoAhead software is unaffected. El archivo websda.c en GoAhead WebServer versión 2.1.8, presenta una entropía nonce insuficiente porque el cálculo del nonce es basado en el valor onceuponatimeinparadise codificado, que no sigue la directriz de datos secretos para la autenticación de acceso HTTP Digest en RFC 7616 sección 3.3 (o RFC 2617 sección 3.2.1). NOTA: 2.1.8 es una versión de 2003; sin embargo, el código websda.c afectado aparece en múltiples trabajos derivados que pueden usarse en 2021. • https://devel.rtems.org/browser/rtems/cpukit/httpd/websda.c?rev=c1427d2758079f0e9dd6a8de1662d78e0d6bc4ca https://github.com/trenta3/goahead-versions/blob/master/2.1.8/230165webs218.tar.gz?raw=true • CWE-331: Insufficient Entropy •

https://notcve.org/view.php?id=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) • https://github.com/embedthis/goahead/issues/304 • CWE-208: Observable Timing Discrepancy CWE-307: Improper Restriction of Excessive Authentication Attempts •
CVSS: 8.8EPSS: 2%CPEs: 1EXPL: 1CVE-2020-15688 – EmbedThis GoAhead Web Server 5.1.1 Digest Authentication Capture Replay Nonce Reuse
https://notcve.org/view.php?id=CVE-2020-15688
The HTTP Digest Authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. This allows an unauthenticated remote attacker to bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel. La autenticación de HTTP Digest en el servidor web de GoAhead versiones anteriores a 5.1.2 no protege completamente contra los ataques de repetición. Esto permite a un atacante remoto no autenticado eludir la autenticación a través de la captura-reproducción si no se utiliza el TLS para proteger el canal de comunicación subyacente A security vulnerability affecting GoAhead versions 2 to 5 has been identified when using Digest authentication over HTTP. The HTTP Digest Authentication in the GoAhead web server does not completely protect against replay attacks. • http://packetstormsecurity.com/files/159505/EmbedThis-GoAhead-Web-Server-5.1.1-Digest-Authentication-Capture-Replay-Nonce-Reuse.html https://github.com/embedthis/goahead-gpl/issues/3 • CWE-294: Authentication Bypass by Capture-replay •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 1CVE-2019-19240
https://notcve.org/view.php?id=CVE-2019-19240
Embedthis GoAhead before 5.0.1 mishandles redirected HTTP requests with a large Host header. The GoAhead WebsRedirect uses a static host buffer that has a limited length and can overflow. This can cause a copy of the Host header to fail, leaving that buffer uninitialized, which may leak uninitialized data in a response. Incruste GoAhead versiones anteriores a 5.0.1, maneja inapropiadamente las peticiones HTTP redireccionadas con un encabezado Host grande. GoAhead WebsRedirect utiliza un búfer de host estático que posee una longitud limitada y puede desbordarse. • https://github.com/embedthis/goahead/issues/289 https://github.com/embedthis/goahead/issues/290 https://github.com/embedthis/goahead/releases/tag/v5.0.1 • CWE-787: Out-of-bounds Write CWE-908: Use of Uninitialized Resource •
CVSS: 8.6EPSS: 1%CPEs: 1EXPL: 2CVE-2019-16645 – GoAhead 2.5.0 - Host Header Injection
https://notcve.org/view.php?id=CVE-2019-16645
An issue was discovered in Embedthis GoAhead 2.5.0. Certain pages (such as 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. Se detectó un problema en Embedthis GoAhead versión 2.5.0. Ciertas páginas (tales como goform/login y config/log_off_page.htm) crean enlaces que contienen un nombre del host obtenido desde un encabezado de Host HTTP arbitrario enviado por parte de un atacante. • https://www.exploit-db.com/exploits/47439 http://packetstormsecurity.com/files/154652/GoAhead-2.5.0-Host-Header-Injection.html https://github.com/Ramikan/Vulnerabilities/blob/master/GoAhead%20Web%20server%20HTTP%20Header%20Injection • CWE-94: Improper Control of Generation of Code ('Code Injection') •
