CVE-2016-0762 – tomcat: timing attack in Realm implementation
https://notcve.org/view.php?id=CVE-2016-0762
The Realm implementations in Apache Tomcat versions 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 process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.

Esto hizo posible la realización de un ataque basado en tiempo para determinar nombres de usuario válidos. • http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.debian.org/security/2016/dsa-3720 http://www.securityfocus.com/bid/93939 http://www.securitytracker.com/id/1037144 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/1872f96bad43647832bdd84a408794cd06d9cbb557af63085ca10009%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/343558d982879bf88e • CWE-203: Observable Discrepancy •
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-2016-6816 – 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-2016-8735 – 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-2016-8745 – 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 •
