Security Bulletin
Summary
There are multiple vulnerabilities in IBM(R) Runtime Environment Java(TM) Versions 6
and 7 used by IBM Process Designer. IBM Process Designer has addressed the
applicable CVEs.
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
This vulnerability affects IBM Business Automation Workflow V18.0.0.0 through
V18.0.0.1, IBM Business Process Manager V7.5.0.0 through V8.6.0 2017.12, and
WebSphere Lombardi Edition V7.2.0.0 through V7.2.0.5.
Remediation/Fixes
The Eclipse-based IBM Process Designer tool includes an instance of IBM(R)
Runtime Environment Java(TM) Versions 6 or 7. To provide the fix for this
development tool, install the APAR JR59944 for your product:
o IBM Business Automation Workflow V18.0.0.1
o IBM Business Automation Workflow V18.0.0.0
o IBM Business Process Manager V8.6
o IBM Business Process Manager Express V8.6
o IBM Business Process Manager Advanced V8.5.7
o IBM Business Process Manager Standard V8.5.7
o IBM Business Process Manager Express V8.5.7
Because support for Java 6 with Business Process Manager ended, if you are on
earlier version of IBM Business Process Manager or WebSphere Lombardi Edition
IBM recommends that you upgrade to IBM Business Process Manager V8.5.7.0
2017.06 or later or IBM Business Automation Workflow and that you apply APAR
JR59944.
Workarounds and Mitigations
CVE-2018-12539 can be mitigated by disabling the Attach API functionality with
the command line option -Dcom.ibm.tools.attach.enable=no
