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 •
CVSS: 5.0EPSS: 6%CPEs: 2EXPL: 0CVE-2015-3183 – httpd: HTTP request smuggling attack against chunked request parser
https://notcve.org/view.php?id=CVE-2015-3183
The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c. Vulnerabilidad en la implementación de la codificación de transferencia fragmentada en el Servidor HTTP Apache en versiones anteriores a la 2.4.14 no analiza adecuadamente los fragmentos de las cabeceras lo cual permite a atacantes remotos efectuar ataques de infiltración de solicitudes HTTP a través de peticiones manipuladas, relacionada con el mal manejo de los valores fragmentados de gran tamaño y extensiones fragmentadas no válidas en modules/http/http_filters.c. Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. • http://httpd.apache.org/security/vulnerabilities_24.html http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10735 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00004.html http://lists.opensuse.org/opensuse-updates/2015-10/msg00011.html http://marc.info/?l=bugtraq&m=144493176821532&w=2 http://rhn.redhat.com/errata/RHSA-2015-1666.html http://rhn.redhat.com/errata/RHSA-2015-1667.html http&# • CWE-17: DEPRECATED: Code CWE-20: Improper Input Validation CWE-172: Encoding Error •

https://notcve.org/view.php?id=CVE-2015-0228
The lua_websocket_read function in lua_request.c in the mod_lua module in the Apache HTTP Server through 2.4.12 allows remote attackers to cause a denial of service (child-process crash) by sending a crafted WebSocket Ping frame after a Lua script has called the wsupgrade function. La función lua_websocket_read en lua_request.c en el módulo mod_lua en Apache HTTP Server hasta 2.4.12 permite a atacantes remotos causar una denegación de servicio (caída del proceso hijo) mediante el envío de un Frame WebSocket Ping manipulado después de que una secuencia de comandos Lua haya llamado a la función wsupgrade. A denial of service flaw was found in the way the mod_lua httpd module processed certain WebSocket Ping requests. A remote attacker could send a specially crafted WebSocket Ping packet that would cause the httpd child process to crash. • http://advisories.mageia.org/MGASA-2015-0099.html http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00004.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00006.html http://rhn.redhat.com/errata/RHSA-2015-1666.html http://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x/CHANGES http://www.oracle.com/technetwork/security-advisory/cpujul2016-2881720.html http://www.oracle.com/technetwork&#x • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-0118
The deflate_in_filter function in mod_deflate.c in the mod_deflate module in the Apache HTTP Server before 2.4.10, when request body decompression is enabled, allows remote attackers to cause a denial of service (resource consumption) via crafted request data that decompresses to a much larger size. La función deflate_in_filter en mod_deflate.c en el módulo mod_deflate en Apache HTTP Server anterior a 2.4.10, cuando la descompresión del cuerpo de una solicitud está habilitada, permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de datos de solicitudes manipulados que descomprime a un tamaño mucho más grande. A denial of service flaw was found in the way httpd's mod_deflate module handled request body decompression (configured via the "DEFLATE" input filter). A remote attacker able to send a request whose body would be decompressed could use this flaw to consume an excessive amount of system memory and CPU on the target system. • http://advisories.mageia.org/MGASA-2014-0304.html http://advisories.mageia.org/MGASA-2014-0305.html http://httpd.apache.org/security/vulnerabilities_24.html http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://marc.info/?l=bugtraq&m=143403519711434&w=2 http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http://marc.info/?l=bugtraq&m=144493176821532&w=2 http://rhn.redhat.com/errata/RHSA-2014 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2014-0231
The mod_cgid module in the Apache HTTP Server before 2.4.10 does not have a timeout mechanism, which allows remote attackers to cause a denial of service (process hang) via a request to a CGI script that does not read from its stdin file descriptor. El módulo mod_cgid en Apache HTTP Server anterior a 2.4.10 no tiene un mecanismo de timeout, lo que permite a atacantes remotos causar una denegación de servicio (cuelgue del proceso) a través de una solicitud en una secuencia de comandos CGI que no lee desde su descriptor de ficheros stdin. A denial of service flaw was found in the way httpd's mod_cgid module executed CGI scripts that did not read data from the standard input. A remote attacker could submit a specially crafted request that would cause the httpd child process to hang indefinitely. • http://advisories.mageia.org/MGASA-2014-0304.html http://advisories.mageia.org/MGASA-2014-0305.html http://httpd.apache.org/security/vulnerabilities_24.html http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://marc.info/?l=bugtraq&m=143403519711434&w=2 http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http://marc.info/?l=bugtraq&m=144493176821532&w=2 http://packetstormsecurity.com/files/130769/ • CWE-399: Resource Management Errors •
