Security Bulletin: Multiple security vulnerabilities in Swagger UI affect IBM Business Automation Workflow and IBM Business Process Manager (BPM)

Summary

IBM Business Process Manager and IBM Business Automation Workflow are affected by multiple security vulnerabilities found in Swagger UI.

Vulnerability Details

CVEID:CVE-2012-6708
**DESCRIPTION:**jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the ‘<’ character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the ‘<’ character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.
CVSS Base score: 6.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/138055 for the current score.

CVEID:CVE-2015-9251
**DESCRIPTION:**jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request is performed without the dataType option, causing text/javascript responses to be executed.
CVSS Base score: 6.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/138029 for the current score.

CVEID:CVE-2019-11358
**DESCRIPTION:**jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, …) because of Object.prototype pollution. If an unsanitized source object contained an enumerable proto property, it could extend the native Object.prototype.

Affected Products and Versions

Remediation/Fixes

The recommended solution is to apply the Interim Fix (iFix) or Cumulative Fix (CF) containing APAR JR61747 as soon as practical:

• IBM Business Automation Workflow (including fix for IBM Business Process Manager V8.6.0.0 2018.03)
• IBM Business Process Manager Advanced
• IBM Business Process Manager Standard
• IBM Business Process Manager Express

Note that JR61747 is superseded by JR62222 addressing an issue with profile upgrade in case the ifix has been applied and is reapplied during upgrade to a newer version, which does not yet have the fix.

For IBM Business Automation Workflow V18.0 and V19.0
· Upgrade to minimal cumulative fix levels as required by iFix and then apply iFix JR61747
--OR–
· Apply cumulative fix Business Automation Workflow V20.0.0.1

For IBM Business Process Manager V8.6
· Upgrade to minimal cumulative fix levels as required by iFix and then apply iFix JR61747
--OR–
· Upgrade to Business Automation Workflow V20.0.0.1
