CVSS: 8.6EPSS: 0%CPEs: 7EXPL: 0CVE-2016-4554 – squid: Header Smuggling issue in HTTP Request processing
https://notcve.org/view.php?id=CVE-2016-4554
mime_header.cc in Squid before 3.5.18 allows remote attackers to bypass intended same-origin restrictions and possibly conduct cache-poisoning attacks via a crafted HTTP Host header, aka a "header smuggling" issue. mime_header.cc en Squid en versiones anteriores a 3.5.18 permite a atacantes remotos eludir restricciones destinadas al mismo origen y posiblemente llevar a cabo ataques de envenenamiento de caché a través de una cabecera HTTP Host manipulada, también conocido como un problema "contrabando de peticiones". An input validation flaw was found in Squid's mime_get_header_field() function, which is used to search for headers within HTTP requests. An attacker could send an HTTP request from the client side with specially crafted header Host header that bypasses same-origin security protections, causing Squid operating as interception or reverse-proxy to contact the wrong origin server. It could also be used for cache poisoning for client not following RFC 7230. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00069.html http://www.debian.org/security/2016/dsa-3625 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securitytracker.com/id/1035769 http://www.squid-cache.org/Advisories/SQUID-2016_8.txt http://www.squid-cache.org/Versions/v3/3.1/changesets&# • CWE-20: Improper Input Validation CWE-345: Insufficient Verification of Data Authenticity •

Buffer overflow in cachemgr.cgi in Squid 2.x, 3.x before 3.5.17, and 4.x before 4.0.9 might allow remote attackers to cause a denial of service or execute arbitrary code by seeding manager reports with crafted data. Desbordamiento de buffer en cachemgr.cgi en Squid 2.x, 3.x en versiones anteriores a 3.5.17 y 4.x en versiones anteriores a 4.0.9 podría permitir a atacantes remotos provocar una denegación de servicio o ejecutar código arbitrario sembrando informes manager con datos manipulados. A buffer overflow flaw was found in the way the Squid cachemgr.cgi utility processed remotely relayed Squid input. When the CGI interface utility is used, a remote attacker could possibly use this flaw to execute arbitrary code. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00069.html http://www.debian.org/security/2016/dsa-3625 http://www.openwall.com/lists/oss-security/2016/04/20/6 http://www.openwall.com/lists/oss-security/2016/04/20/9 http://www.oracle.com/technetwork/security-advisory/cpujul2016-2881720.html http://www.oracle.com/technetwork/t • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

The FwdState::connectedToPeer method in FwdState.cc in Squid before 3.5.14 and 4.0.x before 4.0.6 does not properly handle SSL handshake errors when built with the --with-openssl option, which allows remote attackers to cause a denial of service (application crash) via a plaintext HTTP message. El método FwdState::connectedToPeer en FwdState.cc en Squid en versiones anteriores a 3.5.14 y 4.0.x en versiones anteriores a 4.0.6 no maneja correctamente los errores de apretones de manos SSL cuando se construye con la opción --with-openssl, lo que permite a atacantes remotos causar una denegación de servicio (caída de aplicación) a través de un mensaje HTTP en texto plano. • http://bugs.squid-cache.org/show_bug.cgi?id=4437 http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.squid-cache.org/pipermail/squid-announce/2016-February/000037.html http://lists.squid-cache.org/pipermail/squid-announce/2016-February/000038.html http://www.securitytracker.com/id/1035045 http://www.squid-cache.org/Advisories/SQUID-2016_1.txt • CWE-20: Improper Input Validation •
