CVE-2016-6797 – tomcat: unrestricted access to global resources
https://notcve.org/view.php?id=CVE-2016-6797
The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not limit web application access to global JNDI resources to those resources explicitly linked to the web application. Therefore, it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not. La implementación ResourceLinkFactory en Apache Tomcat 9.0.0.M1 a 9.0.0.M9, 8.5.0 a 8.5.4, 8.0.0.RC1 a 8.0.36, 7.0.0 a 7.0.70 a 6.0.0 a 6.0.45 no limitaba el acceso de las aplicaciones web a recursos globales JNDI a aquellos relacionados explícitamente con la aplicación web. Por lo tanto, era posible que una aplicación web accediese a cualquier recurso global JNDI sin importar si se había configurado un ResourceLink explícito. It was discovered that it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not. • http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.debian.org/security/2016/dsa-3720 http://www.securityfocus.com/bid/93940 http://www.securitytracker.com/id/1037145 https://access.redhat.com/errata/RHSA-2017:0455 https://access.redhat.com/errata/RHSA-2017:0456 https://access.redhat.com/errata/RHSA-2017:2247 https://lists.apache.org/thread.html/343558d982879bf88ec20dbf707f8c11255f8e219e81d45c4f8d0551%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/37220405a377c0182d2afdb • CWE-863: Incorrect Authorization •
CVE-2016-8735 – Apache Tomcat Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2016-8735
Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types. La ejecución remota de código es posible con Apache Tomcat en versiones anteriores a 6.0.48, 7.x en versiones anteriores a 7.0.73, 8.x en versiones anteriores a 8.0.39, 8.5.x en versiones anteriores a 8.5.7 y 9.x en versiones anteriores a 9.0.0.M12 si JmxRemoteLifecycleListener es utilizado y un atacante puede llegar a los puertos JMX. El problema existe porque este oyente no se actualizó por coherencia con el parche de Oracle CVE-2016-3427 que afectó a los tipos de credenciales. The JmxRemoteLifecycleListener was not updated to take account of Oracle's fix for CVE-2016-3427. • http://rhn.redhat.com/errata/RHSA-2017-0457.html http://seclists.org/oss-sec/2016/q4/502 http://svn.apache.org/viewvc?view=revision&revision=1767644 http://svn.apache.org/viewvc?view=revision&revision=1767656 http://svn.apache.org/viewvc?view=revision&revision=1767676 http://svn.apache.org/viewvc?view=revision&revision=1767684 http://tomcat.apache.org/security-6.html http://tomcat.apache.org/security-7.html http://tomcat.apache.org/security-8.html http://tomcat.apache.org • CWE-502: Deserialization of Untrusted Data •
CVE-2016-6816 – Apache Tomcat 6/7/8/9 - Information Disclosure
https://notcve.org/view.php?id=CVE-2016-6816
The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own.

CVE-2016-8745 – tomcat: information disclosure due to incorrect Processor sharing
https://notcve.org/view.php?id=CVE-2016-8745
A bug in the error handling of the send file code for the NIO HTTP connector in Apache Tomcat 9.0.0.M1 to 9.0.0.M13, 8.5.0 to 8.5.8, 8.0.0.RC1 to 8.0.39, 7.0.0 to 7.0.73 and 6.0.16 to 6.0.48 resulted in the current Processor object being added to the Processor cache multiple times. This in turn meant that the same Processor could be used for concurrent requests. Sharing a Processor can result in information leakage between requests including, not not limited to, session ID and the response body. The bug was first noticed in 8.5.x onwards where it appears the refactoring of the Connector code for 8.5.x onwards made it more likely that the bug was observed. Initially it was thought that the 8.5.x refactoring introduced the bug but further investigation has shown that the bug is present in all currently supported Tomcat versions. • http://rhn.redhat.com/errata/RHSA-2017-0457.html http://rhn.redhat.com/errata/RHSA-2017-0527.html http://www.debian.org/security/2017/dsa-3754 http://www.debian.org/security/2017/dsa-3755 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/94828 http://www.securitytracker.com/id/1037432 https://access.redhat.com/errata/RHSA-2017:0455 https://a • CWE-388: 7PK - Errors •
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 •
