Summary
There are multiple vulnerabilities in IBM(R) Runtime Environment Java(TM) Versions
6, 7 and 8, which are used by IBM Rational ClearQuest. These issues were
disclosed as part of the IBM Java SDK updates in July 2018.
Vulnerability Details
CVEID: CVE-2018-1656
DESCRIPTION: The IBM Java Runtime Environment's Diagnostic Tooling Framework
for Java (DTFJ) does not protect against path traversal attacks when extracting
compressed dump files.
CVSS Base Score: 7.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144882 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N)
CVEID: CVE-2018-12539
DESCRIPTION: Eclipse OpenJ9 could allow a local attacker to gain elevated
privileges on the system, caused by the failure to restrict the use of Java
Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and
use Attach API operations to only the process owner. An attacker could exploit
this vulnerability to execute untrusted native code and gain elevated
privileges on the system.
CVSS Base Score: 8.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
148389 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
Affected Products and Versions
IBM Rational ClearQuest version 8 and 9 in the following components:
o ClearQuest Web/CQ OSLC server/CM Server component, when configured to use
SSL.
o ClearQuest Eclipse clients that use Report Designer, run remote reports on
servers using secure connections, or use the embedded browser to connect to
secure web sites. If you do not use the ClearQuest Eclipse client in this
way, then you are not affected.
+---------------------------------------+-------------------------------------+
| ClearQuest version | Status |
+---------------------------------------+-------------------------------------+
| 9.0.1 through 9.0.1.4 | Affected |
+---------------------------------------+-------------------------------------+
| 9.0 through 9.0.0.6 | Affected |
+---------------------------------------+-------------------------------------+
|8.0 through 8.0.0.21 |Affected |
+---------------------------------------+-------------------------------------+
|8.0.1 through 8.0.1.18 |Affected |
+---------------------------------------+-------------------------------------+
Remediation/Fixes
The solution is to install a fix that includes an updated Java(TM) Virtual Machine
with fixes for the issues, and to apply fixes for WebSphere Application Server
(WAS).
ClearQuest Eclipse Clients
Apply the relevant fixes as listed in the table below.
+------------------------+-------------------------------------------------------------------------+
| Affected Versions | Applying the fix |
+------------------------+-------------------------------------------------------------------------+
| 9.0.1 through 9.0.1.4 |Install Rational ClearQuest Fix Pack 5 (9.0.1.5) for 9.0.1 |
| 9.0 through 9.0.0.6 | |
+------------------------+-------------------------------------------------------------------------+
|8.0.1 through 8.0.1.18 |Install Rational ClearQuest Fix Pack 19 (8.0.1.19) for 8.0.1 |
|8.0 through 8.0.0.21 | |
+------------------------+-------------------------------------------------------------------------+
For 7.0, 7.1, 8.0, and earlier releases, IBM recommends upgrading to a fixed,
supported version/release/platform of the product.
ClearQuest Web/CQ OSLC Server/CM Server Component
1. Determine the WAS version used by your CM server. Navigate to the CM
profile directory (either the profile you specified when installing
ClearQuest, or <clearquest-home>/cqweb/cqwebprofile), then execute the
script: bin/versionInfo.sh (UNIX) or bin\versionInfo.bat (Windows). The
output includes a section "IBM WebSphere Application Server". Make note of
the version listed in this section.
2. Review the following WAS security bulletin:
Security Bulletin: Multiple vulnerabilities in IBM(R) Java SDK affects
WebSphere Application Server July 2018 CPU
and apply the latest available fix for the version of WAS used for CM
server.
Note: there may be newer security fixes for WebSphere Application Server.
Follow the link below (in the section "Get Notified about Future Security
Bulletins") to subscribe to WebSphere product support alerts for additional
Java SDK fixes.
+-------------------+---------------------------------------------------------+
| Affected Versions | Applying the fix |
+-------------------+---------------------------------------------------------+
|9.0.0.x |Apply the appropriate WebSphere Application Server fix |
|9.0.1.x |directly to your CM server host. No ClearQuest-specific |
|8.0.1.x |steps are necessary. |
|8.0.0.x | |
+-------------------+---------------------------------------------------------+
Workarounds and Mitigations
None.
