Affected Products and Versions

Remediation/Fixes

Workarounds and Mitigations

Customers who do not use the eFormPlugin can remove the JXPath JAR bundled with IBM Content Navigator from their system.

The vulnerable JXPath package is utilized by the eFormPlugin and IBM Enterprise Records.

Therefore, customers who do not use the eFormPlugin or IBM Enterprise Records are not affected by this vulnerability.

Looking ahead, IBM Content Navigator will remove the JXPath package.

Customers who utilize the plugins are encouraged to validate all data provided by users before calling the affected methods to search for nodes on an XML tree.

Customers who require the JXPath will need to download a newer version of that package separately and add it to their classpath to run their application.

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.
