https://notcve.org/view.php?id=CVE-2017-3167
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, el uso de ap_get_basic_auth_pw() por parte de módulos de terceros fuera de la fase de autenticación puede dar lugar a que se omitan requisitos de autenticación.. It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99135 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://access.redhat.com/errata/RHS • CWE-287: Improper Authentication •

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. En Apache httpd, en versiones 2.2.x anteriores a la 2.2.33 y versiones 2.4.x anteriores a la 2.4.26, mod_ssl podría desreferenciar un puntero NULL cuando los módulos de terceros llaman a ap_hook_process_connection() durante una petición HTTP a un puerto HTPS. A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. • http://www.debian.org/security/2017/dsa-3896 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99134 http://www.securitytracker.com/id/1038711 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:3193 https://access.redhat.com/errata/RHSA-2017:3194 https://access.redhat.com/errata/RHS • CWE-476: NULL Pointer Dereference •

CVSS: 7.5EPSS: 0%CPEs: 27EXPL: 0CVE-2016-8743 – httpd: Apache HTTP Request Parsing Whitespace Defects
https://notcve.org/view.php?id=CVE-2016-8743
Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution. El servidor HTTP Apache, en todas las distribuciones anteriores a la 2.2.32 y la 2.4.25 era liberal en el espacio en blanco aceptado de peticiones y enviado en lineas y cabeceras de respuesta. La aceptación de estos comportamientos diferentes representaba un problema a nivel de seguridad cuando httpd participa en cualquier cadena de proxies o interactúa con servidores de aplicaciones backend, ya sea mediante mod_proxy o utilizando mecanismos CGI convencionales y puede dar lugar al tráfico de peticiones, división de respuestas y contaminación de la caché. It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. • http://rhn.redhat.com/errata/RHSA-2017-1415.html http://www.debian.org/security/2017/dsa-3796 http://www.securityfocus.com/bid/95077 http://www.securitytracker.com/id/1037508 https://access.redhat.com/errata/RHSA-2017:0906 https://access.redhat.com/errata/RHSA-2017:1161 https://access.redhat.com/errata/RHSA-2017:1413 https://access.redhat.com/errata/RHSA-2017:1414 https://access.redhat.com/errata/RHSA-2017:1721 https://h20566.www2.hpe.com/hpsc/doc/public/display • CWE-20: Improper Input Validation •
CVSS: 8.1EPSS: 20%CPEs: 52EXPL: 0CVE-2016-5387 – HTTPD: sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5387
The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability. El Apache HTTP Server hasta la versión 2.4.23 sigue a RFC 3875 sección 4.1.18 y por lo tanto no protege aplicaciones de la presencia de datos de clientes no confiables en ambiente variable de HTTP_PROXY, lo que puede permitir a atacantes remotos redireccionar el tráfico HTTP saliente de aplicación a un servidor proxy arbitrario a través de una cabecera Proxy manipulada en una petición HTTP, también conocido como problema "httpoxy". NOTA: el vendedor afirma "Se ha asignado a esta mitigación el identificador CVE-2016-5387"; en otras palabras, esto no es un CVE ID para una vulnerabilidad. It was discovered that httpd used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00059.html http://rhn.redhat.com/errata/RHSA-2016-1624.html http://rhn.redhat.com/errata/RHSA-2016-1625.html http://rhn.redhat.com/errata/RHSA-2016-1648.html http://rhn.redhat.com/errata/RHSA-2016-1649.html http://rhn.redhat.com/errata/RHSA-2016-1650.html http://www.debian.org/security/2016/dsa-3623 http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html • CWE-20: Improper Input Validation •
