CVE-2016-1000108
https://notcve.org/view.php?id=CVE-2016-1000108
yaws before 2.0.4 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. yaws versiones anteriores a la versión 2.0.4, no intenta abordar los conflictos de espacio de nombres de RFC sección 3875 versión 4.1.18 y, por lo tanto, no protege las aplicaciones CGI de la presencia de datos de clientes no seguros en la variable de entorno HTTP_PROXY, lo que podría permitir a atacantes remotos redireccionar el tráfico HTTP saliente de la aplicación CGI hacia un servidor proxy arbitrario por medio de un encabezado Proxy especialmente diseñado en una petición HTTP, también se conoce como un problema "httpoxy". • http://www.openwall.com/lists/oss-security/2016/07/18/6 https://github.com/klacke/yaws/commit/9d8fb070e782c95821c90d0ca7372fc6d7316c78#diff-54053c47eb173a90c26ed19bd9d106c1 https://raw.githubusercontent.com/distributedweaknessfiling/cvelist/master/2016/1000xxx/CVE-2016-1000108.json https://security-tracker.debian.org/tracker/CVE-2016-1000108 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

CVE-2017-10974 – Yaws 1.91 - Remote File Disclosure
https://notcve.org/view.php?id=CVE-2017-10974
Yaws 1.91 allows Unauthenticated Remote File Disclosure via HTTP Directory Traversal with /%5C../ to port 8080. NOTE: this CVE is only about use of an initial /%5C sequence to defeat traversal protection mechanisms; the initial /%5C sequence was apparently not discussed in earlier research on this product. Yaws 1.91 permite la divulgación remota de archivos sin autenticarse mediante un salto de directorio HTTP con /%5C../ en el puerto 8080. NOTA: Este CVE solo trata el uso de una secuencia /%5C inicial para omitir los mecanismos de protección contra saltos. • https://www.exploit-db.com/exploits/42303 http://hyp3rlinx.altervista.org/advisories/YAWS-WEB-SERVER-v1.91-UNAUTHENTICATED-REMOTE-FILE-DISCLOSURE.txt http://www.securityfocus.com/bid/99515 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
