According to its self-reported version number, the instance of Apache Tomcat 5.5.x listening on the remote host is prior to 5.5.34. It is, there, 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 'jsvc' is     compiled with libpcap and the '-user' parameter is     used. (CVE-2011-2729)

  - Specially crafted requests are incorrectly processed by     Tomcat and can cause the server to allow injection of     arbitrary AJP messages. This can lead to authentication     bypass and disclosure of sensitive information. Note     this vulnerability only occurs when the     org.apache.jk.server.JkCoyoteHandler AJP connector is     not used, POST requests are accepted, and the request     body is not processed.(CVE-2011-3190)

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

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

    Security issues fixed with this release:
    CVE-2010-3718     Apache Tomcat 7.0.0 through 7.0.3, 6.0.x, and 5.5.x, when running within a SecurityManager, does not make     the ServletContext attribute read-only, which allows local web applications to read or write files outside     of the intended working directory, as demonstrated using a directory traversal attack.
    CVE-2011-0013     Multiple cross-site scripting (XSS) vulnerabilities in the HTML Manager Interface in Apache Tomcat 5.5     before 5.5.32, 6.0 before 6.0.30, and 7.0 before 7.0.6 allow remote attackers to inject arbitrary web     script or HTML, as demonstrated via the display-name tag.
    CVE-2011-1184     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.
    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.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

It was discovered that Tomcat incorrectly implemented HTTP DIGEST authentication. An attacker could use this flaw to perform a variety of authentication attacks. (CVE-2011-1184)

Polina Genova discovered that Tomcat incorrectly created log entries with passwords when encountering errors during JMX user creation. A local attacker could possibly use this flaw to obtain sensitive information. This issue only affected Ubuntu 10.04 LTS, 10.10 and 11.04. (CVE-2011-2204)

It was discovered that Tomcat incorrectly validated certain request attributes when sendfile is enabled. A local attacker could bypass intended restrictions, or cause the JVM to crash, resulting in a denial of service. (CVE-2011-2526)

It was discovered that Tomcat incorrectly handled certain AJP requests. A remote attacker could use this flaw to spoof requests, bypass authentication, and obtain sensitive information. This issue only affected Ubuntu 10.04 LTS, 10.10 and 11.04. (CVE-2011-3190).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been discovered and corrected in tomcat 5.5.x :

The implementation of HTTP DIGEST authentication in tomcat was discovered to have several weaknesses (CVE-2011-1184).

Apache Tomcat, 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, 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).

Certain AJP protocol connector implementations in Apache Tomcat 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 (CVE-2011-3190).

The updated packages have been patched to correct these issues.

Fixes for: CVE-2011-3190 - authentication bypass and information disclosure CVE-2011-2526 - send file validation CVE-2011-2204 - password disclosure vulnerability JAVA_HOME setting in tomcat6.conf

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.

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 Scientific 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.

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 Scientific Linux 6. (CVE-2011-2526)

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'.

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.

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.
