CVSS: 8.1EPSS: 92%CPEs: 21EXPL: 0CVE-2016-5385 – PHP: sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5385
PHP through 7.0.8 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts 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, as demonstrated by (1) an application that makes a getenv('HTTP_PROXY') call or (2) a CGI configuration of PHP, aka an "httpoxy" issue. PHP hasta la versión 7.0.8 no intenta abordar los conflictos de espacio de nombres de 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 ppodría permitir a atacantes remotos redireccionar el tráfico HTTP saliente de una aplicación a un servidor proxy arbitrario través de una cabecera Proxy manipulada en una petición HTTP, según lo demostrado por (1) una aplicación que hace una llamada getenv('HTTP_PROXY') o (2) una configuración CGI de PHP, también conocido como problema "httpoxy". It was discovered that PHP did not properly protect against the HTTP_PROXY variable name clash. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a PHP script to an attacker-controlled proxy via a malicious HTTP request. • http://lists.opensuse.org/opensuse-updates/2016-08/msg00003.html http://rhn.redhat.com/errata/RHSA-2016-1609.html http://rhn.redhat.com/errata/RHSA-2016-1610.html http://rhn.redhat.com/errata/RHSA-2016-1611.html http://rhn.redhat.com/errata/RHSA-2016-1612.html http://rhn.redhat.com/errata/RHSA-2016-1613.html http://www.debian.org/security/2016/dsa-3631 http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html • CWE-20: Improper Input Validation CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

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 •

https://notcve.org/view.php?id=CVE-2016-2518
The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. La función MATCH_ASSOC en NTP en versiones anteriores 4.2.8p9 y 4.3.x en versiones anteriores a 4.3.92 permite a atacantes remotos provocar una referencia fuera de los límites a través de una solicitud addpeer con un valor hmode grande. An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183647.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184669.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016& • CWE-125: Out-of-bounds Read •

Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." Desbordamiento de buffer basado en memoria dinámica en la función __nss_hostname_digits_dots en glibc 2.2, y otras versiones 2.x anteriores a 2.18, permite a atacantes dependientes de contexto ejecutar código arbitrario a través de vectores relacionados con la funciín (1) gethostbyname o (2) gethostbyname2, también conocido como 'GHOST.' A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. The industrial managed switch series 852 from WAGO is affected by multiple vulnerabilities such as old software components embedded in the firmware. • https://www.exploit-db.com/exploits/35951 https://www.exploit-db.com/exploits/36421 https://github.com/aaronfay/CVE-2015-0235-test https://github.com/makelinux/CVE-2015-0235-workaround https://github.com/sUbc0ol/CVE-2015-0235 https://github.com/mikesplain/CVE-2015-0235-cookbook https://github.com/tobyzxj/CVE-2015-0235 https://github.com/adherzog/ansible-CVE-2015-0235-GHOST http://blogs.sophos.com/2015/01/29/sophos-products-and-the-ghost-vulnerability-affecting-linux http:/ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
