SSLv3 can be enabled in IBM Rational DOORS Web Access. Vulnerability Details CVE ID: CVE-2014-3566 Description: Product could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt SSL sessions and access the plaintext of encrypted connections. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N) Affected Products and Versions Rational DOORS Web Access version 9.6.0.x, 9.5.2.x, 9.5.1.x, 9.5.0.x, 1.5.0.x, 1.4.0.x. Remediation/Fixes None Workarounds and Mitigations IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3. To avoid this vulnerability, configure the Apache Tomcat server.xml file in your Rational DOORS Web Access installation to disable SSLv3 and instead use TLS v1, v1.1, or v1.2. Procedure: 1. To access the configuration files for Rational DOORS Web Access for SSL or TLS, review the help topic Configuring Rational DOORS Web Access to use SSL or TLS for more details. 2. In the SSL JSSE HTTP Connector section of the server.xml file, set the following values. For Rational DOORS Web Access versions 9.5.2.x, 9.5.1.x, 9.5.0.x, 1.5.0.x, 1.4.0.x (prior to Tomcat 6.0.39): <Connector port="8443" protocol="HTTP/1.1" maxThreads="150" clientAuth="false" SSLEnabled="true" scheme="https" secure="true" sslProtocol="TLS" protocols="TLSv1.2,TLSv1.1,TLSv1"/> For Rational DOORS Web Access versions 9.6.0.x (Tomcat 6.0.39 and later): <Connector port="8443" protocol="HTTP/1.1" maxThreads="150" clientAuth="false" SSLEnabled="true" scheme="https" secure="true" sslProtocol="TLS" sslEnabledProtocols="TLSv1.2,TLSv1.1,TLSv1"/> 3. If you are using APR, use the following values: <Connector... maxThreads="200" enableLookups="true" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" SSLEnabled="true" SSLProtocol="TLSv1" SSLCertificateFile="${catalina.base}/conf/localhost.crt" SSLCertificateKeyFile="${catalina.base}/conf/localhost.key" /> 4. Save and close the server.xml file. 5. Restart the Rational DOORS Web Access server. You can test the SSL/TLS version configuration in Tomcat by running the following commands in openssl: openssl s_client -connect testhost : port -ssl3 Fails if SSLv3 is disabled. openssl s_client -connect testhost : port -tls1 Returns a certificate if TLSv1 is enabled. openssl s_client -connect testhost : port -tls1_1 Returns a certificate if TLSv1.1 is enabled. openssl s_client -connect testhost : port -tls1_2 Returns a certificate if TLSv1.2 is enabled.
