CVE-2016-6325 – tomcat: tomcat writable config files allow privilege escalation
https://notcve.org/view.php?id=CVE-2016-6325
The Tomcat package on Red Hat Enterprise Linux (RHEL) 5 through 7, JBoss Web Server 3.0, and JBoss EWS 2 uses weak permissions for (1) /etc/sysconfig/tomcat and (2) /etc/tomcat/tomcat.conf, which allows local users to gain privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 5 hasta la versión 7, JBoss Web Server 3.0 y JBoss EWS 2 utiliza permisos débiles para (1) /etc/sysconfig/tomcat y (2) /etc/tomcat/tomcat.conf, lo que permite a usuarios locales obtener privilegios aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. • http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93478 https://access.redhat.com/errata/RHSA-2017:0455 https://access.redhat.com/errata/RHSA-2017:0456 https://bugzilla.redhat.com/show_bug.cgi?id=1367447 https://access.redhat.com/security/cve/CVE-2016-6325 • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
CVE-2016-1240 – Apache Tomcat 8/7/6 (Debian-Based Distros) - Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-1240
The Tomcat init script in the tomcat7 package before 7.0.56-3+deb8u4 and tomcat8 package before 8.0.14-1+deb8u3 on Debian jessie and the tomcat6 and libtomcat6-java packages before 6.0.35-1ubuntu3.8 on Ubuntu 12.04 LTS, the tomcat7 and libtomcat7-java packages before 7.0.52-1ubuntu0.7 on Ubuntu 14.04 LTS, and tomcat8 and libtomcat8-java packages before 8.0.32-1ubuntu1.2 on Ubuntu 16.04 LTS allows local users with access to the tomcat account to gain root privileges via a symlink attack on the Catalina log file, as demonstrated by /var/log/tomcat7/catalina.out. El inicio de secuencia de comandos de Tomcat en el paquete tomcat7 en versiones anteriores 7.0.56-3+deb8u4 y el paquete tomcat8 en versiones anteriores 8.0.14-1+deb8u3 en Debian jessie y los paquetes tomcat6 y libtomcat6-java en versiones anteriores 6.0.35-1ubuntu3.8 en Ubuntu 12.04 LTS, los paquetes tomcat7 y libtomcat7-java en versiones anteriores 7.0.52-1ubuntu0.7 en Ubuntu 14.04 LTS y los paquetes tomcat8 y libtomcat8-java en versiones anteriores 8.0.32-1ubuntu1.2 en Ubuntu 16.04 LTS permite a usuarios locales con acceso a la cuenta tomcat obtener privilegios de root a través de un ataque de enlace simbólico en archivo de registro Catalina, según lo demostrado por /var/log/tomcat7/catalina.out. It was reported that the Tomcat init script performed unsafe file handling, which could result in local privilege escalation. Apache Tomcat versions 8.0.36-2 and below, 7.0.70-2 and below, and 6.0.45+dfsg-1~deb8ul and below suffer from a local root privilege escalation vulnerability. • https://www.exploit-db.com/exploits/40450 http://legalhackers.com/advisories/Tomcat-DebPkgs-Root-Privilege-Escalation-Exploit-CVE-2016-1240.html http://packetstormsecurity.com/files/170857/Apache-Tomcat-On-Ubuntu-Log-Init-Privilege-Escalation.html http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.debian.org/security/2016/dsa-3669 http://www.debian.org/security/2016/dsa-3670 http://www.securityfocus.com/archive/1/539519/100/0/threaded http://www.securityfocus.com/bid/93263 http • CWE-20: Improper Input Validation CWE-284: Improper Access Control •
CVE-2016-5388 – Tomcat: CGI sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5388
Apache Tomcat 7.x through 7.0.70 and 8.x through 8.5.4, when the CGI Servlet is enabled, 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 "A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388"; in other words, this is not a CVE ID for a vulnerability. Apache Tomcat, en versiones 7.x hasta la 7.0.70 y versiones 8.x hasta la 8.5.4, cuando el Servlet CGI está habilitado, sigue la sección 4.1.18 de RFC 3875 y, por lo tanto, no protege aplicaciones ante la presencia de datos de cliente no fiables en la variable de entorno HTTP_PROXY. Esto podría permitir que atacantes remotos redirijan el tráfico HTTP saliente de una aplicación a un servidor proxy arbitrario mediante una cabecera Proxy manipulada en una petición HTTP. Esto también se conoce como problema "httpoxy". • http://lists.opensuse.org/opensuse-updates/2016-09/msg00025.html http://rhn.redhat.com/errata/RHSA-2016-1624.html http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/91818 http://www.securitytracker.com/id/ • CWE-20: Improper Input Validation CWE-284: Improper Access Control •
CVE-2015-5345 – tomcat: directory disclosure
https://notcve.org/view.php?id=CVE-2015-5345
The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character. El componente Mapper en Apache Tomcat 6.x en versiones anteriores a 6.0.45, 7.x en versiones anteriores a 7.0.68, 8.x en versiones anteriores a 8.0.30, y 9.x en versiones anteriores a 9.0.0.M2 procesa redirecciones antes de considerar las restricciones y Filtros de seguridad, lo que permite a atacantes remotos determinar la existencia de un directorio a través de una URL que carece de un carácter / (barra) final. It was found that Tomcat could reveal the presence of a directory even when that directory was protected by a security constraint. A user could make a request to a directory via a URL not ending with a slash and, depending on whether Tomcat redirected that request, could confirm whether that directory existed. • http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00069.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00082.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00085.html http://marc.info/?l=bugtraq&m=145974991225029&w=2 http://packetstormsecurity.com/files/135892/Apache-Tomcat-Directory-Disclosure.html http://rhn.redhat.com/errata/RHSA-2016-1089.html http://rhn.redhat • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-552: Files or Directories Accessible to External Parties •
CVE-2015-5174 – tomcat: URL Normalization issue
https://notcve.org/view.php?id=CVE-2015-5174
Directory traversal vulnerability in RequestUtil.java in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.65, and 8.x before 8.0.27 allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINA_BASE/webapps directory. Vulnerabilidad de salto de directorio en RequestUtil.java en Apache Tomcat 6.x en versiones anteriores a 6.0.45, 7.x en versiones anteriores a 7.0.65 y 8.x en versiones anteriores a 8.0.27 permite a usuarios remotos autenticados eludir las restricciones de SecurityManager destinadas y listar un directorio padre a través de un /.. (barra punto punto) en un nombre de ruta utilizado por una aplicación web en una llamada getResource, getResourceAsStream o getResourcePaths, según lo demostrado por el directorio $CATALINA_BASE/webapps.
