Security Bulletin: IBM Sterling B2B Integrator Standard Edition could disclose sensitive information in the HTTP response

Security Bulletin


Summary

In IBM Sterling B2B Integrator's dashboard, many links have CSRF tokens at the end of URLs. An attacker could post something with a link to the B2Bi dashboard somewhere. If a B2Bi user who has the active http session and owns the token clicks the link then the request will be honored since it has the active http session and its associated CSRF token.

Vulnerability Details

CVEID:   CVE-2023-42010
DESCRIPTION:   IBM Sterling B2B Integrator Standard Edition could disclose sensitive information in the HTTP response using man in the middle techniques.
CVSS Base score: 3.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/265507 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)

Affected Products and Versions

Affected Product(s)Version(s)
IBM Sterling B2B Integrator6.2.0.0 - 6.2.0.2
IBM Sterling B2B Integrator6.0.0.0 - 6.1.2.5

Remediation/Fixes

In B2Bi, the CSRF token is not displayed in the history of the browser because the dashboard removes it from browser's URL location bar.  To take advantage of this weakness, the person who clicks the link posted by the attacker must have an active http session and the CSRF token that is associated with that session. Please note that this fix for not showing the CSRF token in browser history is already part of the affected releases of B2Bi and no update or patch is required.

Workarounds and Mitigations

  • Do not use firewall or proxy URL logging in front of the dashboard.  This will store CSRF tokens from B2B's dashboard. 
  • Do not enable web log debugging, since this will also store the URL.  This will store CSRF tokens from B2B's dashboard. 
  • If logging is absolutely necessary for business reasons, there should be very tight controls around accessing the logs.

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.
