Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might allow remote attackers to discover the server's hostname or IP address by sending a request for a resource that requires (1) BASIC or (2) DIGEST authentication, and then reading the realm field in the WWW-Authenticate header in the reply.

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several third-party components and libraries :

  - Apache Tomcat 
  - Apache Tomcat Manager
  - cURL 
  - Java Runtime Environment (JRE)
  - Kernel 
  - Microsoft SQL Express
  - OpenSSL
  - pam_krb5

This update of tomcat fixes denial of service and information disclosure vulnerabilities which could potentially be exploited by remote attackers to crash tomcat or to obtain sensitive information (CVE-2010-2227, CVE-2010-1157).

An updated jbossweb package that fixes two security issues is now available for JBoss Enterprise Application Platform 4.2 and 4.3 for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having important 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.

JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise Application Platform. It provides a single deployment platform for the JavaServer Pages (JSP) and Java Servlet technologies, Microsoft .NET, PHP, and CGI.

A flaw was found in the way JBoss Web handled the Transfer-Encoding header in HTTP requests. A specially crafted HTTP request could prevent JBoss Web from sending replies, or cause JBoss Web to return truncated replies, or replies containing data related to the requests of other users, for all subsequent HTTP requests. (CVE-2010-2227)

A possible minor information leak was found in the way JBoss Web generated HTTP BASIC and DIGEST authentication requests. For configurations where a realm name was not specified and JBoss Web was accessed via a proxy, the default generated realm contained the hostname and port used by the proxy to send requests to the JBoss Web server. (CVE-2010-1157)

Users of JBoss Web should upgrade to this updated package, which upgrades JBoss Web to version 2.0.0.CP14, and resolves these issues.
The JBoss server process must be restarted for this update to take effect.

The remote host is affected by the vulnerability described in GLSA-201206-24 (Apache Tomcat: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Apache Tomcat. Please       review the CVE identifiers referenced below for details.
  Impact :

    The vulnerabilities allow an attacker to cause a Denial of Service, to       hijack a session, to bypass authentication, to inject webscript, to       enumerate valid usernames, to read, modify and overwrite arbitrary files,       to bypass intended access restrictions, to delete work-directory files,       to discover the server&rsquo;s hostname or IP, to bypass read permissions for       files or HTTP headers, to read or write files outside of the intended       working directory, and to obtain sensitive information by reading a log       file.
  Workaround :

    There is no known workaround at this time.

The remote host is running a version of Mac OS X 10.6 that does not have Security Update 2011-006 applied.  This update contains numerous security-related fixes for the following components :

  - Apache
  - Application Firewall
  - ATS
  - BIND
  - Certificate Trust Policy
  - CFNetwork
  - CoreFoundation
  - CoreMedia
  - File Systems
  - IOGraphics
  - iChat Server
  - Mailman
  - MediaKit
  - PHP
  - postfix
  - python
  - QuickTime
  - Tomcat
  - User Documentation
  - Web Server
  - X11

Various vulnerabilities have been discovered in the Tomcat Servlet and JSP engine, resulting in denial of service, cross-site scripting, information disclosure and WAR file traversal. Further details on the individual security issues can be found on the Apache Tomcat 5 vulnerabilities page.

a. vCenter Server and vCenter Update Manager update Microsoft    SQL Server 2005 Express Edition to Service Pack 3

   Microsoft SQL Server 2005 Express Edition (SQL Express)    distributed with vCenter Server 4.1 Update 1 and vCenter Update    Manager 4.1 Update 1 is upgraded from  SQL Express Service Pack 2    to SQL Express Service Pack 3, to address multiple security    issues that exist in the earlier releases of Microsoft SQL Express.

   Customers using other database solutions need not update for    these issues.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2008-5416, CVE-2008-0085, CVE-2008-0086,    CVE-2008-0107 and CVE-2008-0106 to the issues addressed in MS SQL    Express Service Pack 3.

b. vCenter Apache Tomcat Management Application Credential Disclosure

   The Apache Tomcat Manager application configuration file contains    logon credentials that can be read by unprivileged local users.

   The issue is resolved by removing the Manager application in    vCenter 4.1 Update 1.

   If vCenter 4.1 is updated to vCenter 4.1 Update 1 the logon    credentials are not present in the configuration file after the    update.

   VMware would like to thank Claudio Criscione of Secure Networking    for reporting this issue to us.

   - The update also addresses CVE-2010-2240 for ESX 4.0.

Versions of Tomcat 5.x earlier than 5.5.30 are potentially affected by multiple vulnerabilities : 

  - The 'WWW-Authenticate' HTTP header for BASIC and DIGEST authentcation may expose the local host name or IP address of the machine running Tomcat. (CVE-2010-1157)

  - Several flaws in the handling of the 'Tansfer-Encoding' header could prevent the recycling of  buffer. (CVE-2010-2227)

  - When running under a SecurityManager, it is possible for web applications to be granted read/write permissions to any area on the file system. (CVE-2010-3718)

Versions of Tomcat 6.x earlier than 6.0.28 are potentially affected by multiple vulnerabilities : 

  - The 'WWW-Authenticate' HTTP header for BASIC and DIGEST authentication could potentially expose the local host name or IP adddress of the machine running Tomcat. (CVE-2010-1157)

  - Several flaws in handling of the 'Transfer-Encoding' header exist that could prevent the recycling of a buffer. (CVE-2010-2227)

According to its self-reported version number, the instance of Apache Tomcat 6.0 listening on the remote host is prior to 6.0.28. It is, therefore, affected by multiple vulnerabilities:

 - If a web app is configured to use BASIC or DIGEST authentication and the 'realm-name' attribute is not configured in that web app's 'web.xml' file, the remote server's hostname or IP will be included in replies. (CVE-2010-1157)

 - An error exists in the handling of invalid values in the 'Transfer-Encoding' header of a request. An attacker can exploit this to cause a denial of service or to disclose sensitive information. (CVE-2010-2227)

Note that Nessus Network Monitor 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 Apache Tomcat server listening on the remote host is 5.5.x prior to 5.5.30. It is, therefore, affected by multiple vulnerabilities:

 - An error in the access restriction on a 'ServletContext' attribute which holds the location of the work directory in Tomcat's SecurityManager. A remote attacker may be able to modify the location of the working directory which then allows improper read and write access to arbitrary files and directories in the context of Tomcat.(CVE-2010-3718)

 - An error exists in the handling of the 'Transfer-Encoding' header of a client request. This error affects buffer recycling and may lead to the disclosure of sensitive information or allow a denial of service attack to be successful. (CVE-2010-2227)

 - An error exists in the handling of the '<realm-name>' element in a web application's web.xml file. If the element is missing from the web.xml file and the application is using BASIC or DIGEST authentication, Tomcat will include the server's hostname or IP address in the 'WWW-Authenticate' header of the response. (CVE-2010-1157)

Note that Nessus Network Monitor did not actually test for the flaws but instead has relied on the version in Tomcat's banner or error page so this may be a false positive.

This update of tomcat fixes denial of service and information disclosure vulnerabilities which could potentially be exploited by remote attackers to crash tomcat or to obtain sensitive information.
(CVE-2010-2227 / CVE-2010-1157)

This update of tomcat fixes a denial of service vulnerability and two information disclosure flaws which could potentially be exploited by remote attackers to crash tomcat or to obtain sensitive information.
(CVE-2010-2227, CVE-2010-1157)

Multiple vulnerabilities has been found and corrected in tomcat5 :

Directory traversal vulnerability in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20 allows remote attackers to create or overwrite arbitrary files via a .. (dot dot) in an entry in a WAR file, as demonstrated by a ../../bin/catalina.bat entry (CVE-2009-2693).

The autodeployment process in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20, when autoDeploy is enabled, deploys appBase files that remain from a failed undeploy, which might allow remote attackers to bypass intended authentication requirements via HTTP requests (CVE-2009-2901).

Directory traversal vulnerability in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20 allows remote attackers to delete work-directory files via directory traversal sequences in a WAR filename, as demonstrated by the ...war filename (CVE-2009-2902).

Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might allow remote attackers to discover the server's hostname or IP address by sending a request for a resource that requires (1) BASIC or (2) DIGEST authentication, and then reading the realm field in the WWW-Authenticate header in the reply (CVE-2010-1157).

Apache Tomcat 5.5.0 through 5.5.29, 6.0.0 through 6.0.27, and 7.0.0 beta does not properly handle an invalid Transfer-Encoding header, which allows remote attackers to cause a denial of service (application outage) or obtain sensitive information via a crafted header that interferes with recycling of a buffer. (CVE-2010-2227)

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
http://store.mandriva.com/product_info.php?cPath=149&amp;products_id=4 90

The updated packages have been patched to correct these issues.

Multiple vulnerabilities has been found and corrected in tomcat5 :

Apache Tomcat 6.0.0 through 6.0.14, 5.5.0 through 5.5.25, and 4.1.0 through 4.1.36 does not properly handle (1) double quote (') characters or (2) %5C (encoded backslash) sequences in a cookie value, which might cause sensitive information such as session IDs to be leaked to remote attackers and enable session hijacking attacks. NOTE:
this issue exists because of an incomplete fix for CVE-2007-3385 (CVE-2007-5333).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, 6.0.0 through 6.0.18, and possibly earlier versions normalizes the target pathname before filtering the query string when using the RequestDispatcher method, which allows remote attackers to bypass intended access restrictions and conduct directory traversal attacks via .. (dot dot) sequences and the WEB-INF directory in a Request (CVE-2008-5515).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when the Java AJP connector and mod_jk load balancing are used, allows remote attackers to cause a denial of service (application outage) via a crafted request with invalid headers, related to temporary blocking of connectors that have encountered errors, as demonstrated by an error involving a malformed HTTP Host header (CVE-2009-0033).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when FORM authentication is used, allows remote attackers to enumerate valid usernames via requests to /j_security_check with malformed URL encoding of passwords, related to improper error checking in the (1) MemoryRealm, (2) DataSourceRealm, and (3) JDBCRealm authentication realms, as demonstrated by a % (percent) value for the j_password parameter (CVE-2009-0580).

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).

Directory traversal vulnerability in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20 allows remote attackers to create or overwrite arbitrary files via a .. (dot dot) in an entry in a WAR file, as demonstrated by a ../../bin/catalina.bat entry (CVE-2009-2693).

The autodeployment process in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20, when autoDeploy is enabled, deploys appBase files that remain from a failed undeploy, which might allow remote attackers to bypass intended authentication requirements via HTTP requests (CVE-2009-2901).

Directory traversal vulnerability in Apache Tomcat 5.5.0 through 5.5.28 and 6.0.0 through 6.0.20 allows remote attackers to delete work-directory files via directory traversal sequences in a WAR filename, as demonstrated by the ...war filename (CVE-2009-2902).

Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might allow remote attackers to discover the server's hostname or IP address by sending a request for a resource that requires (1) BASIC or (2) DIGEST authentication, and then reading the realm field in the WWW-Authenticate header in the reply (CVE-2010-1157).

Apache Tomcat 5.5.0 through 5.5.29, 6.0.0 through 6.0.27, and 7.0.0 beta does not properly handle an invalid Transfer-Encoding header, which allows remote attackers to cause a denial of service (application outage) or obtain sensitive information via a crafted header that interferes with recycling of a buffer.

The updated packages have been patched to correct these issues.

According to its self-reported version number, the instance of Apache Tomcat 6.0 listening on the remote host is prior to 6.0.28. It is, therefore, affected by multiple vulnerabilities:

  - If a web app is configured to use BASIC or DIGEST     authentication and the 'realm-name' attribute is not     configured in that web app's 'web.xml' file, the remote     server's hostname or IP will be included in replies.
    (CVE-2010-1157)

  - An error exists in the handling of invalid values in     the 'Transfer-Encoding' header of a request. An attacker     can exploit this to cause a denial of service or to     disclose sensitive information. (CVE-2010-2227)

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 Apache Tomcat server listening on the remote host is 5.5.x prior to 5.5.30. It is, therefore, affected by multiple vulnerabilities :

  - An error in the access restriction on a 'ServletContext'     attribute which holds the location of the work     directory in Tomcat's SecurityManager. A remote attacker     may be able to modify the location of the working     directory which then allows improper read and write     access to arbitrary files and directories in the context     of Tomcat.(CVE-2010-3718)

  - An error exists in the handling of the     'Transfer-Encoding' header of a client request. This     error affects buffer recycling and may lead to the     disclosure of sensitive information or allow a denial     of service attack to be successful. (CVE-2010-2227)

  - An error exists in the handling of the '<realm-name>'     element in a web application's web.xml file. If the     element is missing from the web.xml file and the     application is using BASIC or DIGEST authentication,     Tomcat will include the server's hostname or IP address     in the 'WWW-Authenticate' header of the response.
    (CVE-2010-1157)

Note that Nessus did not actually test for the flaws but instead has relied on the version in Tomcat's banner or error page so this may be a false positive.

The Apache software foundation reports :

The 'WWW-Authenticate' header for BASIC and DIGEST authentication includes a realm name. If a <realm-name> element is specified for the application in web.xml it will be used. However, a <realm-name> is not specified then Tomcat will generate one.

In some circumstances this can expose the local hostname or IP address of the machine running Tomcat.
