The version of Tomcat installed on the remote host is prior to 7.0.32. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_7.0.32_security-7 advisory.

  - org/apache/catalina/filters/CsrfPreventionFilter.java in Apache Tomcat 6.x before 6.0.36 and 7.x before     7.0.32 allows remote attackers to bypass the cross-site request forgery (CSRF) protection mechanism via a     request that lacks a session identifier. (CVE-2012-4431)

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

Updated jbossweb packages for JBoss Enterprise Application Platform 6.0.1 that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 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.

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.

It was found that sending a request without a session identifier to a protected resource could bypass the Cross-Site Request Forgery (CSRF) prevention filter in JBoss Web. A remote attacker could use this flaw to perform CSRF attacks against applications that rely on the CSRF prevention filter and do not contain internal mitigation for CSRF.
(CVE-2012-4431)

Multiple weaknesses were found in the JBoss Web DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887)

Warning: Before applying this update, back up your existing JBoss Enterprise Application Platform installation and deployed applications.

All users of JBoss Enterprise Application Platform 6.0.1 on Red Hat Enterprise Linux 5 and 6 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.

The remote host is affected by the vulnerability described in GLSA-201412-29 (Apache Tomcat: Multiple vulnerabilities)

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

    A remote attacker may be able to cause a Denial of Service condition as       well as obtain sensitive information, bypass protection mechanisms and       authentication restrictions.
  Workaround :

    There is no known workaround at this time.

According to its self-reported version number, the instance of Apache Tomcat 6.0 listening on the remote host is prior to Tomcat 6.0.36. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists within the parseHeaders() function that     allows for a crafted header to cause a remote denial of     service. (CVE-2012-2733)

  - An error exists related to FORM authentication that     allows a security bypass if 'j_security_check' is     appended to the request. (CVE-2012-3546)

  - An error exists in the file     'filters/CsrfPreventionFilter.java' that allows     cross-site request forgery (XSRF) attacks to bypass     the filtering. This can allow access to protected     resources without a session identifier. (CVE-2012-4431)

  - An error exists related to the 'NIO' connector when     HTTPS and 'sendfile' are enabled that can force the     application into an infinite loop. (CVE-2012-4534)

  - Replay-countermeasure functionality in HTTP Digest     Access Authentication tracks cnonce values instead of     nonce values, which makes it easier for attackers to     bypass access restrictions by sniffing the network for     valid requests. (CVE-2012-5885)

  - The HTTP Digest Access Authentication implementation     caches information about the authenticated user, which     allows an attacker to bypass authentication via session     ID. (CVE-2012-5886)

  - The HTTP Digest Access Authentication implementation     does not properly check for stale nonce values with     enforcement of proper credentials, which allows an     attacker to bypass restrictions by sniffing requests.
    (CVE-2012-5887)

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

The Apache Software Foundation reports :

The CSRF prevention filter could be bypassed if a request was made to a protected resource without a session identifier present in the request.

Updated tomcat6 packages that fix multiple security issues are now available for JBoss Enterprise Web Server 2.0.0 for Red Hat Enterprise Linux 5 and 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.

It was found that sending a request without a session identifier to a protected resource could bypass the Cross-Site Request Forgery (CSRF) prevention filter. A remote attacker could use this flaw to perform CSRF attacks against applications that rely on the CSRF prevention filter and do not contain internal mitigation for CSRF.
(CVE-2012-4431)

A flaw was found in the way Tomcat handled sendfile operations when using the HTTP NIO (Non-Blocking I/O) connector and HTTPS. A remote attacker could use this flaw to cause a denial of service (infinite loop). The HTTP NIO connector is used by default in JBoss Enterprise Web Server. The Apache Portable Runtime (APR) connector from the Tomcat Native library was not affected by this flaw. (CVE-2012-4534)

Multiple weaknesses were found in the Tomcat DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887)

A denial of service flaw was found in the way the Tomcat HTTP NIO connector enforced limits on the permitted size of request headers. A remote attacker could use this flaw to trigger an OutOfMemoryError by sending a specially crafted request with very large headers. The HTTP NIO connector is used by default in JBoss Enterprise Web Server. The APR connector from the Tomcat Native library was not affected by this flaw. (CVE-2012-2733)

Warning: Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files).

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

This update of tomcat6 fixes the following security issues :

  - denial of service. (CVE-2012-4534)

  - tomcat: HTTP NIO connector OOM DoS via a request with     large headers. (CVE-2012-2733)

  - tomcat: cnonce tracking weakness. (CVE-2012-5885)

  - tomcat: authentication caching weakness. (CVE-2012-5886)

  - tomcat: stale nonce weakness. (CVE-2012-5887)

  - tomcat: affected by slowloris DoS. (CVE-2012-5568)

  - tomcat: Bypass of security constraints. (CVE-2012-3546)

  - tomcat: bypass of CSRF prevention filter.
    (CVE-2012-4431)

The version of JBoss Enterprise Portal Platform on the remote system is affected by the following issues:

  - A flaw in CSRF prevention filter in JBoss Web could allow     remote attackers to bypass the cross-site request forgery     (CSRF) protection mechanism via a request that lacks a     session identifier. (CVE-2012-4431)

  - A flaw that occurs when the COOKIE session tracking     method is used can allow attackers to hijack users'     sessions. (CVE-2012-4529)

  - A flaw that occurs when multiple applications use the     same custom authorization module class name can allow a     local attacker to deploy a malicious application that     overrides the custom authorization modules provided by     other applications. (CVE-2012-4572)

  - The framework does not verify that a specified     cryptographic algorithm is allowed by the     WS-SecurityPolicy AlgorithmSuite definition before     decrypting.  This can allow remote attackers to force     the system to use weaker cryptographic algorithms than     intended and makes it easier to decrypt communications.
    (CVE-2012-5575)

  - A flaw in PicketBox can allow local users to obtain the     admin encryption key by reading the Vault data file.
    (CVE-2013-1921)

  - A session fixation flaw was found in the     FormAuthenticator module. (CVE-2013-2067)

  - A flaw that occurs when a JGroups channel was started     results in the JGroups diagnostics service being enabled     by default with no authentication via IP multicast. A     remote attacker can make use of this flaw to read     diagnostics information. (CVE-2013-2102)

  - A flaw in the StAX parser implementation can allow     remote attackers to cause a denial of service via     crafted XML. (CVE-2013-2160)

  - A flaw in Apache Santuario XML Security can allow     context-dependent attackers to spoof an XML Signature     by using the CanonicalizationMethod parameter to     specify an arbitrary weak algorithm. (CVE-2013-2172)

  - A flaw in JGroup's DiagnosticsHandler can allow remote     attackers to obtain sensitive information and execute     arbitrary code by re-using valid credentials.
    (CVE-2013-4112)

  - A flaw in the manner in which authenticated connections     were cached on the server by remote-naming can allow     remote attackers to hijack sessions by using a remoting     client. (CVE-2013-4128)

  - A flaw in the manner in which connections for EJB     invocations were cached on the server can allow remote     attackers to hijack sessions by using an EJB client.
    (CVE-2013-4213)
