Security Bulletin
Summary
The Apache Tomcat application server in installations of IBM Rational DOORS
Web Access version contains security vulnerabilities.
Vulnerability Details
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-2014-0227
Description: Apache Tomcat is vulnerable to HTTP request smuggling. A remote
attacker could send a specially-crafted request in a malformed chunked header
to the Web server to cause multiple processing conflicts on the servers. An
attacker could exploit this vulnerability to poison the web cache, bypass web
application firewall protection, and conduct XSS attacks.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100751 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-7810
Description: Apache Tomcat could allow a remote attacker to bypass security
restrictions, caused by the use of expression language. An attacker could
exploit this vulnerability to bypass the protections of a Security Manager.
CVSS Base Score: 5.0
CVSS Temporal Score:
https://exchange.xforce.ibmcloud.com/vulnerabilities/103155 for more
information
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-0230
Description: Apache Tomcat is vulnerable to a denial of service, caused by
missing limitations on request body size. By sending a specially crafted
request to the server, an attacker could keep a connection open and force
Tomcat to keep a processing thread allocated to the connection.
CVSS Score: 5.00
CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P

2. Rename the server directory to server.orig.
3. Extract the Apache Tomcat server archive that was supplied by Support to
./server in the Rational DOORS Web Access installation directory.
4. Copy your ./server.orig/festival directory to ./server/festival.
5. Copy the ./server.orig/conf/server.xml file to ./server/conf/server.xml.
6. Copy ./server.orig/webapps/*.war to ./server/webapps.
7. Optional: Copy any customized files from the ./server.orig directory to
./server.
8. 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.
