Security Bulletin


Summary

There are multiple vulnerabilities in IBM® Runtime Environment Java™ 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® Runtime Environment Java™ Versions 6 or 7. To provide the fix for this development tool, install the APAR JR59944 for your product:

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
