CVSS: 8.1EPSS: 17%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: 0%CPEs: 46EXPL: 0CVE-2015-3184 – subversion: Mixed anonymous/authenticated path-based authz with httpd 2.4
https://notcve.org/view.php?id=CVE-2015-3184
mod_authz_svn in Apache Subversion 1.7.x before 1.7.21 and 1.8.x before 1.8.14, when using Apache httpd 2.4.x, does not properly restrict anonymous access, which allows remote anonymous users to read hidden files via the path name. Vulnerabilidad en mod_authz_svn en Apache Subversion 1.7.x en versiones anteriores a 1.7.21 y 1.8.x en versiones anteriores a 1.8.14, al utilizar Apache httpd 2.4.x, no restringe correctamente el acceso anónimo, lo que permite a usuarios anónimos remotos leer archivos ocultos a través del nombre de la ruta. It was found that the mod_authz_svn module did not properly restrict anonymous access to Subversion repositories under certain configurations when used with Apache httpd 2.4.x. This could allow a user to anonymously access files in a Subversion repository, which should only be accessible to authenticated users. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00003.html http://lists.opensuse.org/opensuse-updates/2015-08/msg00022.html http://rhn.redhat.com/errata/RHSA-2015-1742.html http://subversion.apache.org/security/CVE-2015-3184-advisory.txt http://www.debian.org/security/2015/dsa-3331 http://www.securityfocus.com/bid/76274 http://www.securitytracker.com/id/1033215 http://www.ubuntu.com/usn/USN-2721-1 https://security.gentoo.org/glsa/201610-05 https://support • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-285: Improper Authorization •

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 •
CVSS: 7.5EPSS: 95%CPEs: 18EXPL: 4CVE-2014-0226 – Apache httpd mod_status Heap Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-0226
Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c. Condición de carrera en el módulo mod_status en Apache HTTP Server anterior a 2.4.10 permite a atacantes remotos causar una denegación de servicio (desbordamiento de buffer basado en memoria dinámica), o posiblemente obtener información sensible de credenciales o ejecutar código arbitrario, a través de una solicitud manipulada que provoca el manejo indebido de la tabla de clasificación (scoreboard) dentro de la función status_handler en modules/generators/mod_status.c y la función lua_ap_scoreboard_worker en modules/lua/lua_request.c. A race condition flaw, leading to heap-based buffer overflows, was found in the mod_status httpd module. A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module (MPM) could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the "apache" user. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apache HTTPD server. • https://www.exploit-db.com/exploits/34133 https://github.com/shreesh1/CVE-2014-0226-poc 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&# • CWE-122: Heap-based Buffer Overflow CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2013-5704
The mod_headers module in the Apache HTTP Server 2.2.22 allows remote attackers to bypass "RequestHeader unset" directives by placing a header in the trailer portion of data sent with chunked transfer coding. NOTE: the vendor states "this is not a security issue in httpd as such."
