Some versions of Rational DOORS Web Access are shipped with an Apache Tomcat
application server that contains security vulnerabilities. Apache Tomcat has
been updated to incorporate fixes for these vulnerabilities.
Rational DOORS Web Access is affected by the following vulnerabilities:
CVE ID: CVE-2013-4322
Description: Apache Tomcat is vulnerable to a denial of service, caused by an
incomplete fix related to the processing of chunked transfer coding without
properly handling a large total amount of chunked data or whitespace
characters in an HTTP header value. A remote attacker could exploit this
vulnerability to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91625 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: ( AV:N/AC:L/AU:N/C:N/I:N/A:P)
CVE ID: CVE-2013-4590
Description: Apache Tomcat could allow a remote attacker to obtain sensitive
information, caused by an XML External Entity Injection (XXE) error when
running untrusted web applications. By sending a specially-crafted request, an
attacker could exploit this vulnerability to read arbitrary files and obtain
sensitive information.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91424 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/AU:N/C:P/I:N/A:N)
CVE ID: CVE-2014-0096
Description: Apache Tomcat could allow a remote attacker to obtain sensitive
information, caused by an XML External Entity Injection (XXE) error when
processing XML data by the default server. By sending specially-crafted XML
data, an attacker could exploit this vulnerability to obtain sensitive
information.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93367 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/AU:N/C:P/I:N/A:N)
CVE ID: CVE-2014-0099
Description: Apache Tomcat could allow a remote attacker to obtain sensitive
information, caused by the failure to check for overflows when parsing content
length headers. By sending specially-crafted request, an attacker could
exploit this vulnerability to obtain sensitive information.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93369 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/AU:N/C:P/I:N/A:N)
CVE ID: CVE-2014-0119
Description: Apache Tomcat could allow a remote attacker to obtain sensitive
information, caused by the replacement of the XML parsers used to process
XSLTs for the default servlet. An attacker could exploit this vulnerability
using a specially-crafted application to obtain sensitive information.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93368 for the
current score
CVSS Environmental Score*: Undefined

Remediation/Fixes
You can upgrade Apache Tomcat after installing Rational DOORS Web Access.
To obtain the updated version of the Apache Tomcat, contact IBM Support.
Support can help identify the latest Apache Tomcat that is compatible with
your operating system and platform. Publicly available versions of the Apache
Tomcat are not supported with Rational DOORS Web Access.
The following table presents Rational DOORS Web Access versions and the
compatible versions of Apache Tomcat.
Rational DOORS Web Access Apache Tomcat
1.4.0.4 6.0.41
1.5.0.x 6.0.41
9.5.0.x 6.0.41
9.5.1.x 6.0.41
9.5.2.x 6.0.41
9.6.0.x 7.0.54
After you obtain the Apache Tomcat update from Support do these steps:
Procedure:
Go to the Rational DOORS Web Access installation directory.
For example:
C:\Program Files (x86)\IBM\Rational\DOORS Web Access\9.version
Rename the server directory to server.orig.
Extract the Apache Tomcat server archive that was supplied by Support to
./server in the Rational DOORS Web Access installation directory.
Copy your ./server.orig/festival directory to ./server/festival.
Copy the ./server.orig/conf/server.xml file to ./server/conf/server.xml.
Copy ./server.orig/webapps/*.war to ./server/webapps.
Optional: Copy any customized files from the ./server.orig directory to
./server.
UNIX systems only: Run the ./configure-festival.sh command, as described in
the help topic Installing the web access server and the web access broker on
Linux or Solaris systems.
