The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-0623 advisory.

    - Resolves: rhbz 882010 CVE-2012-3439 CVE-2012-5885 CVE-2012-5886 CVE-2012-5887
    - Resolves: rhbz 883692 CVE-2012-4534 Denial of service when using

Tenable has extracted the preceding description block directly from the Oracle Linux 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 the Apache Tomcat HTTP NIO connector incorrectly handled header data. A remote attacker could cause a denial of service by sending requests with a large amount of header data. (CVE-2012-2733)

It was discovered that Apache Tomcat incorrectly handled DIGEST authentication. A remote attacker could possibly use these flaws to perform a replay attack and bypass authentication. (CVE-2012-5885, CVE-2012-5886, CVE-2012-5887).

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.

A flaw was found in the way the tomcat6 init script handled the tomcat6-initd.log log file. A malicious web application deployed on Tomcat could use this flaw to perform a symbolic link attack to change the ownership of an arbitrary system file to that of the tomcat user, allowing them to escalate their privileges to root. (CVE-2013-1976)

Note: With this update, tomcat6-initd.log has been moved from /var/log/tomcat6/ to the /var/log/ directory.

It was found that the SLSA-2013:0623 update did not correctly fix CVE-2012-5887, a weakness in the Tomcat DIGEST authentication implementation. A remote attacker could use this flaw to perform replay attacks in some circumstances. Additionally, this problem also prevented users from being able to authenticate using DIGEST authentication. (CVE-2013-2051)

Tomcat must be restarted for this update to take effect.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:0631 advisory.

    JBoss Web is a web container based on Apache Tomcat. It provides a single     deployment platform for the JavaServer Pages (JSP) and Java Servlet     technologies.

    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 Web Platform installation (including all applications and     configuration files).

    All users of JBoss Enterprise Web Platform 5.2.0 on Red Hat Enterprise     Linux 4, 5, and 6 are advised to upgrade to these updated packages. The     JBoss server process must be restarted for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The remote Solaris system is missing necessary patches to address security updates :

  - java/org/apache/coyote/http11/InternalNioInputBuffer.jav     a in the HTTP NIO connector in Apache Tomcat 6.x before     6.0.36 and 7.x before 7.0.28 does not properly restrict     the request-header size, which allows remote attackers     to cause a denial of service (memory consumption) via a     large amount of header data. (CVE-2012-2733)

  - org/apache/catalina/realm/RealmBase.java in Apache     Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when     FORM authentication is used, allows remote attackers to     bypass security-constraint checks by leveraging a     previous setUserPrincipal call and then placing     /j_security_check at the end of a URI. (CVE-2012-3546)

  - 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)

  - org/apache/tomcat/util/net/NioEndpoint.java in Apache     Tomcat 6.x before 6.0.36 and 7.x before 7.0.28, when the     NIO connector is used in conjunction with sendfile and     HTTPS, allows remote attackers to cause a denial of     service (infinite loop) by terminating the connection     during the reading of a response. (CVE-2012-4534)

  - The replay-countermeasure functionality in the HTTP     Digest Access Authentication implementation in Apache     Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x     before 7.0.30 tracks cnonce (aka client nonce) values     instead of nonce (aka server nonce) and nc (aka     nonce-count) values, which makes it easier for remote     attackers to bypass intended access restrictions by     sniffing the network for valid requests, a different     vulnerability than CVE-2011-1184. (CVE-2012-5885)

  - The HTTP Digest Access Authentication implementation in     Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36,     and 7.x before 7.0.30 caches information about the     authenticated user within the session state, which makes     it easier for remote attackers to bypass authentication     via vectors related to the session ID. (CVE-2012-5886)

  - The HTTP Digest Access Authentication implementation in     Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36,     and 7.x before 7.0.30 does not properly check for stale     nonce values in conjunction with enforcement of proper     credentials, which makes it easier for remote attackers     to bypass intended access restrictions by sniffing the     network for valid requests. (CVE-2012-5887)

According to its self-reported version number, the instance of Apache Tomcat 5.5.x listening on the remote host is prior to 5.5.36. It is, therefore, affected by the following vulnerabilities :

  - 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)

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

  - 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)

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2013-370:01 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. Tomcat is intended to be a collaboration of the best-of-breed developers from around the world.
    We invite you to participate in this open development project. To learn more about getting involved, click     here.
    Security issues fixed with this release:
    CVE-2012-3546     org/apache/catalina/realm/RealmBase.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when     FORM authentication is used, allows remote attackers to bypass security-constraint checks by leveraging a     previous setUserPrincipal call and then placing /j_security_check at the end of a URI.
    CVE-2012-5885     The replay-countermeasure functionality in the HTTP Digest Access Authentication implementation in Apache     Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 tracks cnonce (aka client nonce)     values instead of nonce (aka server nonce) and nc (aka nonce-count) values, which makes it easier for     remote attackers to bypass intended access restrictions by sniffing the network for valid requests, a     different vulnerability than CVE-2011-1184.
    CVE-2012-5886     The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before     6.0.36, and 7.x before 7.0.30 caches information about the authenticated user within the session state,     which makes it easier for remote attackers to bypass authentication via vectors related to the session ID.
    CVE-2012-5887     The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before     6.0.36, and 7.x before 7.0.30 does not properly check for stale nonce values in conjunction with     enforcement of proper credentials, which makes it easier for remote attackers to bypass intended access     restrictions by sniffing the network for valid requests.
    Fixed bugs:
     The RELINK script is now called only if required bu the user: this solves some potential data loss     windows when a problem occured duting Tomcat start if the RELINK script was running.
     Previously, the tomcat server would remove the single- or double-quotes from cookie names but the then     the cookie values would be empty when passed to a servlet. This has been fixed.
     The OPTION request did not return the TRACE method as an allowed method and incorrectly reported TRACE as     an allowed method. This has been fixed.
     Previously, Tomcat crashed with a NullPointerException if the context.xml file did not specify the     docBase property. This situation is now handled and the path name to the context is used as     docBase.Reminder: when deploying a context, the docBase attribute is mandatory.
     On IBM S/390 and 64-bit PowerPC systems, the Tomcat Administration Tool crashed and accessing failed with     HTTP 404 because the JSP pre-compilation was disabled. JSP is now pre-compiled to prevent compilation at     runtime and the Tomcat Administration Tool is accessible.
     tomcat reported a NullPointerException when a context was deployed with a web application and the     etc/localhost/[webapp].xml file existed; this has been fixed.
     Added the missing tomcat-juli.jar library in Tomcat which prevented java.util.logging from working.
     The /etc/init.d/tomcat5 script returned an incorrect exit status when stopped. This has been fixed.

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.
