Security Bulletin: SQL Injection for IBM Rational ClearQuest Maintenance tool 
(CVE-2011-1390)

Flash (Alert)
 
Abstract
The ClearQuest Maintenance tool on Microsoft Windows platforms contains a 
feature to upgrade the user database. This feature is subject to a SQL Injection 
attack. 

Content

CVE ID: CVE-2011-1390  

Description: A defect has been discovered in the ClearQuest Maintenance tool 
that allows a SQL Injection attack when upgrading the user database. This 
attack requires that an attacker has access to run the ClearQuest Maintenance 
tool on your desktop and can connect directly to your ClearQuest repositories. 

The attack allows arbitrary SQL to be executed against the connected 
repositories. A SQL Injection attack can result in data corruption and loss. 

This attack requires access to and running of the ClearQuest Maintenance tool 
on a Windows platform and having a direct database connection to a ClearQuest 
dbset from the Maintenance tool. 

This attack does not involve the ClearQuest Web Client, ClearQuest Client, or 
ClearQuest Client for Windows, or command line tools. 

CVSS*: 
CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/71802 for the current 
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
 
Affected Platforms: Any supported Microsoft Windows platform. 
Remediation: Upgrade to ClearQuest version 

7.1.1.9 http://www.ibm.com/support/docview.wss?uid=swg24032093 

or 

7.1.2.6 http://www.ibm.com/support/docview.wss?uid=swg24032095 

or 

8.0.0.2 http://www.ibm.com/support/docview.wss?uid=swg24032097 

Workarounds: Do not deploy ClearQuest to user's desktops; use the ClearQuest Web 
client instead. Run ClearQuest on Linux or Unix platforms since the ClearQuest 
Maintenance tool is not installed on those platforms. 

Mitigation: Do not let untrusted users use your desktop applications. Always 
provide periodic backups of your ClearQuest dbsets. Do not reveal your dbset 
connection information to untrusted users. Place your dbsets on local networks 
with trusted users.
