The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character. El módulo mod_proxy del servidor HTTP Apache 1.3.x hasta la versión 1.3.42, 2.0.x hasta la 2.0.64 y 2.2.x hasta la 2.2.21 no interactúa apropiadamente con el uso de coincidencias de patrones de (1) RewriteRule y (2) ProxyPassMatch para la configuración de proxys inversos, lo que permite a atacantes remotos enviar peticiones a servidores de intranet a través de URIs malformadas que contengan un carácter inicial @ (arroba). Context discovered a security vulnerability which allows for Apache in reverse proxy mode to be used to access internal/DMZ systems due to a weakness in its handling of URLs being processed by mod_rewrite. Versions 1.3 and 2.x are affected. • https://www.exploit-db.com/exploits/17969 https://github.com/SECFORCE/CVE-2011-3368 https://github.com/colorblindpentester/CVE-2011-3368 http://kb.juniper.net/JSA10585 http://lists.apple.com/archives/security-announce/2012/Sep/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2011-11/msg00011.html http://lists.opensuse.org/opensuse-updates/2013-02/msg00009.html http://lists.opensuse.org/opensuse-updates/2013-02/msg00012.html http://marc.info/?l=bugtraq&m=133294460209 • CWE-20: Improper Input Validation •

Integer overflow in the ap_proxy_send_fb function in proxy/proxy_util.c in mod_proxy in the Apache HTTP Server before 1.3.42 on 64-bit platforms allows remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a large chunk size that triggers a heap-based buffer overflow. Desbordamiento de enteros en la función ap_proxy_send_fb en proxy/proxy_util.c en mod_proxy en el servidor HTTP Apache anterior a v1.3.42 en plataformas de 64 bits permite a los servidores de origen remoto provocar una denegación de servicio (cuelgue del demonio) o posiblemente ejecutar código arbitrario a través de un fragmento de gran tamaño que provoca un desbordamiento de búfer basado en memoria dinámica. • http://archives.neohapsis.com/archives/fulldisclosure/2010-01/0589.html http://blog.pi3.com.pl/?p=69 http://httpd.apache.org/dev/dist/CHANGES_1.3.42 http://lists.opensuse.org/opensuse-security-announce/2010-04/msg00006.html http://marc.info/?l=bugtraq&m=130497311408250&w=2 http://packetstormsecurity.org/1001-exploits/modproxy-overflow.txt http://secunia.com/advisories/38319 http://secunia.com/advisories/39656 http://site.pi3.com.pl/adv/mod_proxy.txt http://www.sec • CWE-189: Numeric Errors •

The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. El protocolo TLS y el protocolo SSL v3.0 y posiblemente versiones anteriores, tal y como se usa en Microsoft Internet Information Services (IIS) v7.0, mod_ssl en el servidor HTTP Apache v2.2.14 y anteriores, OpenSSL antes de v0.9.8l, GnuTLS v2.8.5 y anteriores, Mozilla Network Security Services (NSS) v3.12.4 y anteriores, y otros productos, no asocia apropiadamente la renegociación del Handshake SSL en una conexión existente, lo que permite ataques man-in-the-middle en los que el atacante inserta datos en sesiones HTTPS, y posiblemente otro tipo de sesiones protegidas por SSL o TLS, enviando una petición de autenticación que es procesada retroactivamente por un servidor en un contexto post-renegociación. Se trata de un ataque de "inyección de texto plano", también conocido como el problema del "Proyecto Mogul". • https://www.exploit-db.com/exploits/10071 https://www.exploit-db.com/exploits/10579 http://archives.neohapsis.com/archives/bugtraq/2013-11/0120.html http://blog.g-sec.lu/2009/11/tls-sslv3-renegotiation-vulnerability.html http://blogs.iss.net/archive/sslmitmiscsrf.html http://blogs.sun.com/security/entry/vulnerability_in_tls_protocol_during http://clicky.me/tlsvuln http://extendedsubset.com/?p=8 http://extendedsubset.com/Renegotiating_TLS.pdf http://h20000.www2.hp.com/bizsuppo • CWE-295: Improper Certificate Validation CWE-300: Channel Accessible by Non-Endpoint •
