Affected Products and Versions
| Affected Product(s) | Version(s) |
| IBM Tivoli Application Dependency Discovery Manager | 7.3.0.0-7.3.0.10 |
Remediation/Fixes
In order to fix this vulnerability, Java needs to be upgraded to 8.0.7.20 for TADDM versions 7.3.0.5 - 7.3.0.10.
Check java version installed on TADDM servers using the below command:
$COLLATION_HOME/external/<jdk- folder according to OS>/bin/java -version
- For TADDM 7.3.0.5 - 7.3.0.10 (JAVA 8), if the above command output contains "SR6 FP10" or "8.0.6.10" or higher as build in Java(TM) SE Runtime Environment information, apply e-fix for the new IBM SDK only, efix_jdk8.0.7.20_FP10221123.zip given in Table-1 below.
- For TADDM 7.3.0.0 - 7.3.0.4 (JAVA 7), Please upgrade to IBM Tivoli Application Dependency Discovery Manager Version 7.3.0.5 or later (Preferably to the latest release 7.3.0.10).
- For all other cases:
The remediation consists of 2 steps:
- Please contact IBM Support and open a case for a custom version of e-Fix "customJDK8.0.6.10" as this efix involves TADDM code changes. Include the current e-Fix level (ls -rlt etc/efix*), TADDM version and a link to this bulletin.
- Along with the above efix, apply efix for the new IBM SDK as per TADDM version given in table below.
Table-1:
Please review the eFix readme in etc/efix_readme.txt. The fixes for the respective FixPack(s) can be downloaded and applied directly.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
