Security Bulletin
Summary
IBM Integration Bus is vulnerable to a remote attack due to Apache Jena
(CVE-2021-39239, CVE-2022-28890, CVE-2023-22665).
Vulnerability Details
CVEID: CVE-2023-22665
DESCRIPTION: Apache Jena could allow a remote attacker to execute arbitrary
code on the system, caused by improper checking of user queries. By sending a
specially crafted SPARQL query, an attacker could exploit this vulnerability to
execute arbitrary javascript on the system.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
253583 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2021-39239
DESCRIPTION: Apache Jena could allow a remote attacker to obtain sensitive
information, caused by improper handling of XML external entity (XXE)
declarations. By using a specially-crafted XML content, a remote attacker could
exploit this vulnerability to read arbitrary files on the server.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
209530 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2022-28890
DESCRIPTION: Apache Jena could allow a remote attacker to obtain sensitive
information, caused by improper handling of XML external entity (XXE)
declarations by the RDF/XML parser. By sending a specially-crafted request, a
remote attacker could exploit this vulnerability to obtain the external DTD
information, and use this information to launch further attacks against the
affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
225725 for the current score.

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.
