Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the instance of Apache Tomcat 6.0.x listening on the remote host is prior to 6.0.33. It is, therefore, affected by multiple vulnerabilities :

  - Several weaknesses were found in the HTTP Digest     authentication implementation. The issues are as     follows: replay attacks are possible, server nonces     are not checked, client nonce counts are not checked,     'quality of protection' (qop) values are not checked,     realm values are not checked and the server secret is     a hard-coded, known string. The effect of these issues     is that Digest authentication is no stronger than Basic     authentication. (CVE-2011-1184, CVE-2011-5062,     CVE-2011-5063, CVE-2011-5064)

  - An error handling issue exists related to the     MemoryUserDatabase that allows user passwords to be     disclosed through log files. (CVE-2011-2204)

  - An input validation error exists that allows a local     attacker to either bypass security or carry out denial     of service attacks when the APR or NIO connectors are     enabled. (CVE-2011-2526)

  - A component that Apache Tomcat relies on called 'jsvc'     contains an error in that it does not drop capabilities     after starting and can allow access to sensitive files     owned by the super user. Note this vulnerability only     affects Linux operating systems and only when the     following are true: jsvc is compiled with libpcap and     the '-user' parameter is used. (CVE-2011-2729)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is running a version of Mac OS X 10.6 that does not have Security Update 2012-001 applied. This update contains multiple security-related fixes for the following components :

  - Apache
  - ATS
  - ColorSync
  - CoreAudio
  - CoreMedia
  - CoreText
  - curl
  - Data Security
  - dovecot

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-03:01 advisory.

    Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet     and JavaServer Pages technologies.
    The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community     Process.
    Tomcat is developed in an open and participatory environment and released under the Apache Software     License version 2.0. Tomcat is intended to be a collaboration of the best-of-breed developers from around     the world.
    Security issues fixed with this release:
    CVE-2011-1184     No information available at the time of writing, please use the CVE link below.
    CVE-2011-2204     Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.17, when the MemoryUserDatabase     is used, creates log entries containing passwords upon encountering errors in JMX user creation, which     allows local users to obtain sensitive information by reading a log file.
    CVE-2011-2526     Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.19, when sendfile is enabled for     the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users     to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by     leveraging an untrusted web application.
    CVE-2011-3190     Certain AJP protocol connector implementations in Apache Tomcat 7.0.0 through 7.0.20, 6.0.0 through     6.0.33, 5.5.0 through 5.5.33, and possibly other versions allow remote attackers to spoof AJP requests,     bypass authentication, and obtain sensitive information by causing the connector to interpret a request     body as a new request.

The following security issues were fixed in tomcat :

  - Fixed a tomcat user password information leak.
    (CVE-2011-2204)

  - Fixed a tomcat information leak and DoS (CVE-2011-2526)

Fix for CVE-2011-3190 This release is the first using a systemd unit file. SystemV files are packaged separately. During this transition users may experience this error: 'error reading information on service tomcat6: No such file or directory' The error occurs because there is no tomcat service to delete. It has been tested, is harmless, and can be ignored.

Resolves: regression in /usr/sbin/tomcat6 (Additionally Created Instances of Tomcat are broken) Bug fix 669969 - dbcp configuration CVE-2011-2204 Added missing commons-pool to lib reverted eclipse osgi manifests to the preceding version.

Updated tomcat6 packages that fix several security issues and one bug are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

APR (Apache Portable Runtime) as mentioned in the CVE-2011-3190 and CVE-2011-2526 descriptions does not refer to APR provided by the apr packages. It refers to the implementation of APR provided by the Tomcat Native library, which provides support for using APR with Tomcat. This library is not shipped with Red Hat Enterprise Linux 6.
This update includes fixes for users who have elected to use APR with Tomcat by taking the Tomcat Native library from a different product.
Such a configuration is not supported by Red Hat, however.

Multiple flaws were found in the way Tomcat handled HTTP DIGEST authentication. These flaws weakened the Tomcat HTTP DIGEST authentication implementation, subjecting it to some of the weaknesses of HTTP BASIC authentication, for example, allowing remote attackers to perform session replay attacks. (CVE-2011-1184)

A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor) and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ Protocol) connectors processed certain POST requests. An attacker could send a specially crafted request that would cause the connector to treat the message body as a new request. This allows arbitrary AJP messages to be injected, possibly allowing an attacker to bypass a web application's authentication checks and gain access to information they would otherwise be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler) connector is used by default when the APR libraries are not present. The JK connector is not affected by this flaw. (CVE-2011-3190)

A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception occurred when creating a new user with a JMX client, that user's password was logged to Tomcat log files. Note: By default, only administrators have access to such log files. (CVE-2011-2204)

A flaw was found in the way Tomcat handled sendfile request attributes when using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious web application running on a Tomcat instance could use this flaw to bypass security manager restrictions and gain access to files it would otherwise be unable to access, or possibly terminate the Java Virtual Machine (JVM). The HTTP blocking IO (BIO) connector, which is not vulnerable to this issue, is used by default in Red Hat Enterprise Linux 6. (CVE-2011-2526)

Red Hat would like to thank the Apache Tomcat project for reporting the CVE-2011-2526 issue.

This update also fixes the following bug :

* Previously, in certain cases, if 'LANG=fr_FR' or 'LANG=fr_FR.UTF-8' was set as an environment variable or in '/etc/sysconfig/tomcat6' on 64-bit PowerPC systems, Tomcat may have failed to start correctly.
With this update, Tomcat works as expected when LANG is set to 'fr_FR' or 'fr_FR.UTF-8'. (BZ#748807)

Users of Tomcat should upgrade to these updated packages, which contain backported patches to correct these issues. Tomcat must be restarted for this update to take effect.

Updated tomcat5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

It was found that web applications could modify the location of the Tomcat host's work directory. As web applications deployed on Tomcat have read and write access to this directory, a malicious web application could use this flaw to trick Tomcat into giving it read and write access to an arbitrary directory on the file system.
(CVE-2010-3718)

A cross-site scripting (XSS) flaw was found in the Manager application, used for managing web applications on Apache Tomcat. A malicious web application could use this flaw to conduct an XSS attack, leading to arbitrary web script execution with the privileges of victims who are logged into and viewing Manager application web pages. (CVE-2011-0013)

Multiple flaws were found in the way Tomcat handled HTTP DIGEST authentication. These flaws weakened the Tomcat HTTP DIGEST authentication implementation, subjecting it to some of the weaknesses of HTTP BASIC authentication, for example, allowing remote attackers to perform session replay attacks. (CVE-2011-1184)

A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception occurred when creating a new user with a JMX client, that user's password was logged to Tomcat log files. Note: By default, only administrators have access to such log files. (CVE-2011-2204)

Users of Tomcat should upgrade to these updated packages, which contain backported patches to correct these issues. Tomcat must be restarted for this update to take effect.

Several vulnerabilities have been found in Tomcat, a servlet and JSP engine :

  - CVE-2011-1184 CVE-2011-5062 CVE-2011-5063 CVE-2011-5064     The HTTP Digest Access Authentication implementation     performed insufficient countermeasures against replay     attacks.

  - CVE-2011-2204     In rare setups passwords were written into a logfile.

  - CVE-2011-2526     Missing input sanitising in the HTTP APR or HTTP NIO     connectors could lead to denial of service.

  - CVE-2011-3190     AJP requests could be spoofed in some setups.

  - CVE-2011-3375     Incorrect request caching could lead to information     disclosure.

  - CVE-2011-4858 CVE-2012-0022     This update adds countermeasures against a collision     denial of service vulnerability in the Java hashtable     implementation and addresses denial of service     potentials when processing large amounts of requests.

The version of Tomcat installed on the remote host is prior to 7.0.19. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_7.0.19_security-7 advisory.

  - Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.19, when sendfile is enabled for     the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users     to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by     leveraging an untrusted web application. (CVE-2011-2526)

  - Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.17, when the MemoryUserDatabase     is used, creates log entries containing passwords upon encountering errors in JMX user creation, which     allows local users to obtain sensitive information by reading a log file. (CVE-2011-2204)

  - Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18 permits web     applications to replace an XML parser used for other web applications, which allows local users to read or     modify the (1) web.xml, (2) context.xml, or (3) tld files of arbitrary web applications via a crafted     application that is loaded earlier than the target application. (CVE-2009-0783)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Certain AJP protocol connector implementations in Apache Tomcat 7.0.0 through 7.0.20, 6.0.0 through 6.0.33, 5.5.0 through 5.5.33, and possibly other versions allow remote attackers to spoof AJP requests, bypass authentication, and obtain sensitive information by causing the connector to interpret a request body as a new request.

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not have the expected countermeasures against replay attacks, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests, related to lack of checking of nonce (aka server nonce) and nc (aka nonce-count or client nonce count) values.

Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.17, when the MemoryUserDatabase is used, creates log entries containing passwords upon encountering errors in JMX user creation, which allows local users to obtain sensitive information by reading a log file.

The following security issues were fixed in tomcat :

  - Fixed a tomcat user password information leak     (CVE-2011-2204)

  - Fixed atomcat information leak and DoS (CVE-2011-2526)

Also one bug was fixed :

  - fix bnc#702289 - suse manager pam ldap authentication     fails

  - source CATALINA_HOME/bin/setenv.sh if exists
