Reference #: 0793587
Modified date: 30 January 2019
IBM WebSphere Application Server (WAS) is shipped as a component of IBM
Rational ClearQuest. Information about a security vulnerability affecting WAS
has been published in a security bulletin.
Refer to the security bulletin(s) listed in the Remediation/Fixes section.
Affected Products and Versions
IBM Rational ClearQuest, ClearQuest CM Server component.
Versions 8.0.0.x, 8.0.1.x, 9.0.0.x, 9.0.1.x:
This vulnerability only applies to the server component, and only for certain
levels of WebSphere Application Server.
Refer to the following security bulletin for vulnerability details and
information about fixes addressed by IBM WebSphere Application Server (WAS),
which is shipped with IBM Rational ClearQuest.
There is a potential cross-site scripting vulnerability with the Installation
Verification Tool (IVT) of WAS. On a standalone application server profile,
the "ivtApp" application is used by the IVT. The application is also
available as an installable Enterprise Application aRchive (EAR) file which
is located at <WAS_HOME>/installableApps/ivtApp.ear.
It will require manual steps from an administrator/user to update a
profile/server-configuration that has already had the ivtApp.ear deployed
either from profile creation or by an administrator/user.
The profile directory is either the profile you specified when installing
ClearQuest, or <clearquest-home>/cqweb/cqwebprofile.
If your profile only hosts the ClearQuest applications, uninstall the ivtApp
from its profile. If your profile hosts other applications and you have a
further need for the ivtApp, then it should be updated or uninstalled and
reinstalled with the updated ivtApp.ear from
See the details in the WAS bulletin on how to manually uninstall the ivtApp.
