java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Tomcat/JBossWeb: request smuggling and limited DoS in ChunkedInputFilter (CVE-2014-0227)

  - Apache Tomcat before 6.0.39, 7.x before 7.0.47, and 8.x before 8.0.0-RC3, when an HTTP connector or AJP     connector is used, does not properly handle certain inconsistent HTTP request headers, which allows remote     attackers to trigger incorrect identification of a request's length and conduct request-smuggling attacks     via (1) multiple Content-Length headers or (2) a Content-Length header and a Transfer-Encoding: chunked     header. NOTE: this vulnerability exists because of an incomplete fix for CVE-2005-2090. (CVE-2013-4286)

  - Integer overflow in the parseChunkHeader function in     java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat before 6.0.40, 7.x before     7.0.53, and 8.x before 8.0.4 allows remote attackers to cause a denial of service (resource consumption)     via a malformed chunk size in chunked transfer coding of a request during the streaming of data.
    (CVE-2014-0075)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Multiple security vulnerabilities have been fixed in the Tomcat servlet and JSP engine, which may result on bypass of security manager restrictions, information disclosure, denial of service or session fixation.

The remote IBM Storwize device is running a version that is 1.3.x prior to 1.4.3.4 or 1.5.x prior to 1.5.0.2. It is, therefore, affected by multiple vulnerabilities :

  - A denial of service vulnerability exists due to a flaw     in the bundled version of Apache HTTP Server. A remote     attacker can exploit this, via partial HTTP requests,     to cause a daemon outage, resulting in a denial of     service condition. (CVE-2007-6750)

  - An HTTP request smuggling vulnerability exists due to a     flaw in the bundled version of Apache Tomcat; when an     HTTP connector or AJP connector is used, Tomcat fails to     properly handle certain inconsistent HTTP request     headers. A remote attacker can exploit this flaw, via     multiple Content-Length headers or a Content-Length     header and a 'Transfer-Encoding: chunked' header, to     smuggle an HTTP request in one or more Content-Length     headers. (CVE-2013-4286)

  - A denial of service vulnerability exists in the bundled     version of Apache Tomcat due to improper processing of     chunked transfer coding with a large amount of chunked     data or whitespace characters in an HTTP header value     within a trailer field. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition. (CVE-2013-4322)

  - A denial of service vulnerability exists due to a flaw     in the bundled version of Apache Tomcat; an integer     overflow condition exists in the parseChunkHeader()     function in ChunkedInputFilter.java. A remote attacker     can exploit this, via a malformed chunk size that is     part of a chunked request, to cause excessive     consumption of resources, resulting in a denial of     service condition. (CVE-2014-0075)

  - A remote code execution vulnerability exists due to a     flaw in the bundled version of Apache Struts. A remote     attacker can manipulate the ClassLoader via the class     parameter, resulting in the execution of arbitrary Java     code. (CVE-2014-0094)

  - An XML External Entity (XXE) injection vulnerability     exists due to a flaw in the bundled version of Apache     Tomcat; an incorrectly configured XML parser accepts     XML external entities from an untrusted source via XSLT.
    A remote attacker can exploit this, by sending specially     crafted XML data, to gain access to arbitrary files.
    (CVE-2014-0096)

  - An integer overflow condition exists in the bundled     version of Apache Tomcat. A remote attacker, via a     crafted Content-Length HTTP header, can conduct HTTP     request smuggling attacks. (CVE-2014-0099)

  - An information disclosure vulnerability exists due to a     flaw in the bundled version of Apache Tomcat. Tomcat     fails to properly constrain the class loader that     accesses the XML parser used with an XSLT stylesheet. A     remote attacker can exploit this, via a crafted web     application that provides an XML external entity     declaration in conjunction with an entity reference, to     read arbitrary files. (CVE-2014-0119)

  - A flaw exists in a bundled version of Samba due to a     flaw in the vfswrap_fsctl() function that is triggered     when responding to FSCTL_GET_SHADOW_COPY_DATA or     FSCTL_SRV_ENUMERATE_SNAPSHOTS client requests. An     unauthenticated, remote attacker can exploit this, via     a specially crafted request, to disclose sensitive     information from process memory. (CVE-2014-0178)

  - Multiple flaws exist in the bundled version of Mozilla     Firefox that allow a remote attacker to execute     arbitrary code. (CVE-2014-1555, CVE-2014-1556,     CVE-2014-1557)

  - An information disclosure vulnerability exists due to     the chkauth password being saved in plaintext in the     audit log. A local attacker can exploit this to gain     administrator access. (CVE-2014-3077)

  - A denial of service vulnerability exists due to a flaw     in the bundled version of Samba. An authenticated,     remote attacker can exploit this, via an attempt to read     a Unicode pathname without specifying the use of     Unicode, to cause an application crash. (CVE-2014-3493)   
  - A security bypass vulnerability exists due to an     unspecified flaw. A remote attacker can exploit this     flaw to reset the administrator password to its default     value via a direct request to the administrative IP     address. Note that this vulnerability only affects the     1.4.x release levels. (CVE-2014-4811)

It was discovered that JBoss Web / Apache Tomcat did not limit the length of chunk sizes when using chunked transfer encoding. A remote attacker could use this flaw to perform a denial of service attack against JBoss Web / Apache Tomcat by streaming an unlimited quantity of data, leading to excessive consumption of server resources.
(CVE-2014-0075)

It was found that the org.apache.catalina.servlets.DefaultServlet implementation in JBoss Web / Apache Tomcat allowed the definition of XML External Entities (XXEs) in provided XSLTs. A malicious application could use this to circumvent intended security restrictions to disclose sensitive information. (CVE-2014-0096)

It was found that JBoss Web / Apache Tomcat did not check for overflowing values when parsing request content length headers. A remote attacker could use this flaw to perform an HTTP request smuggling attack on a JBoss Web / Apache Tomcat server located behind a reverse proxy that processed the content length header correctly.
(CVE-2014-0099)

It was discovered that the ChunkedInputFilter in Tomcat did not fail subsequent attempts to read input after malformed chunked encoding was detected. A remote attacker could possibly use this flaw to make Tomcat process part of the request body as new request, or cause a denial of service. (CVE-2014-0227)

Updated tomcat package fixes security vulnerabilities :

It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library.

It was discovered that Apache Tomcat did not limit the length of chunk sizes when using chunked transfer encoding. A remote attacker could use this flaw to perform a denial of service attack against Tomcat by streaming an unlimited quantity of data, leading to excessive consumption of server resources. (CVE-2014-0075)

It was found that Apache Tomcat did not check for overflowing values when parsing request content length headers. A remote attacker could use this flaw to perform an HTTP request smuggling attack on a Tomcat server located behind a reverse proxy that processed the content length header correctly. (CVE-2014-0099)

It was found that the org.apache.catalina.servlets.DefaultServlet implementation in Apache Tomcat allowed the definition of XML External Entities (XXEs) in provided XSLTs. A malicious application could use this to circumvent intended security restrictions to disclose sensitive information. (CVE-2014-0096)

The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product Security.

This update also fixes the following bug :

The tomcat6-lib-6.0.37-19_patch_04.ep6.el5 package, provided as a dependency of Red Hat JBoss Web Server 2.0.1, included a build of commons-dbcp.jar that used an incorrect java package name, causing applications using this dependency to not function properly. With this update, the java package name has been corrected. (BZ#1101287)

All users of Red Hat JBoss Web Server 2.0.1 are advised to upgrade to these updated tomcat6 packages, which contain backported patches to correct these issues. The Red Hat JBoss Web Server process must be restarted for the update to take effect.

The version of Tomcat installed on the remote host is prior to 8.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_8.0.5_security-8 advisory.

  - Integer overflow in the parseChunkHeader function in     java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat before 6.0.40, 7.x before     7.0.53, and 8.x before 8.0.4 allows remote attackers to cause a denial of service (resource consumption)     via a malformed chunk size in chunked transfer coding of a request during the streaming of data.
    (CVE-2014-0075)

  - java/org/apache/coyote/ajp/AbstractAjpProcessor.java in Apache Tomcat 8.x before 8.0.4 allows remote     attackers to cause a denial of service (thread consumption) by using a Content-Length: 0 AJP request to     trigger a hang in request processing. (CVE-2014-0095)

  - java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before     6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows     remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web     application that provides an XML external entity declaration in conjunction with an entity reference,     related to an XML External Entity (XXE) issue. (CVE-2014-0096)

  - Integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat before 6.0.40, 7.x before     7.0.53, and 8.x before 8.0.4, when operated behind a reverse proxy, allows remote attackers to conduct     HTTP request smuggling attacks via a crafted Content-Length HTTP header. (CVE-2014-0099)

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

The version of Tomcat installed on the remote host is prior to 7.0.53. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_7.0.53_security-7 advisory.

  - Integer overflow in the parseChunkHeader function in     java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat before 6.0.40, 7.x before     7.0.53, and 8.x before 8.0.4 allows remote attackers to cause a denial of service (resource consumption)     via a malformed chunk size in chunked transfer coding of a request during the streaming of data.
    (CVE-2014-0075)

  - java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before     6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows     remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web     application that provides an XML external entity declaration in conjunction with an entity reference,     related to an XML External Entity (XXE) issue. (CVE-2014-0096)

  - Integer overflow in java/org/apache/tomcat/util/buf/Ascii.java in Apache Tomcat before 6.0.40, 7.x before     7.0.53, and 8.x before 8.0.4, when operated behind a reverse proxy, allows remote attackers to conduct     HTTP request smuggling attacks via a crafted Content-Length HTTP header. (CVE-2014-0099)

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 6.0.40. It is, therefore, affected by the following vulnerabilities :

  - An error exists related to chunk size and chunked     requests that allows denial of service attacks.
    (CVE-2014-0075)

  - An error exists related to XSLT handling and security     managers that allows a security bypass related to     external XML entities. (CVE-2014-0096)

  - An error exists related to content length header     handling and using the application behind a reverse     proxy that allows a security bypass. (CVE-2014-0099)

  - An error exists that allows undesired XML parsers to be     injected into the application by a malicious web     application, allows the bypassing of security controls,     and allows the processing of external XML entities.
    (CVE-2014-0119)

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