Security Bulletin


Summary

Apache Tomcat is vulnerable to a security issue affecting the Rational Test Control Panel component in IBM Rational Test Workbench and Rational Test Virtualization Server.

Vulnerability Details

CVE-ID: CVE-2017-5664

Description: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by the improper handling of specific HTTP request methods for static error pages by the Default Servlet error page mechanism. By sending a specially crafted GET request, an attacker could exploit this vulnerability to bypass HTTP method restrictions and cause the deletion or replacement of the target error page.

CVSS Base Score: 6.5
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/126962 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L)

Affected Products and Versions

Rational Test Control Panel component in Rational Test Virtualization Server and Rational Test Workbench versions:

  • 8.5
  • 8.5.0.1
  • 8.5.0.2
  • 8.5.0.3
  • 8.5.0.4
Versions 8.5.1 and later are unaffected as they do not use Apache Tomcat.

Remediation/Fixes

The fix for the CVE mentioned above has been incorporated into the 7.0.81 release of Apache Tomcat. You should upgrade your installation by following the instructions below:

  1. Download the fix for your product from Fix Central:
2. Unzip downloaded file to a directory.

3. Stop the server.

4. In the existing RTCP installation, save the files logging.properties and server.xml to a separate location.

The default installation locations for these files are:
  • Windows: C:\Program Files\IBM\RationalTestControlPanel\conf\
  • AIX, Linux, Solaris: /opt/IBM/RationalTestControlPanel/conf/
5. Copy the contents of the unzipped Tomcat directory (except for the LICENSE file) into the RationalTestControlPanel directory, overwriting the existing files.

6. Copy the two configuration files you saved earlier back into /conf.

7. Start the server.

Notes:
  • When updating an installation to a later version of Rational Test Control Panel, the security fix detailed above will have to be re-applied after the RTCP update
  • When removing an installation that has had the security fix applied, not all the files will be removed by IBM Installation Manager, and some files will have to be removed manually.
