Security Bulletin: Due to the use of XStream, IBM Tivoli Netcool Configuration Manager is vulnerable to Denial of Service (DoS) attacks (CVE-2022-40153)

Security Bulletin


Summary

XStream is used in ITNCM to serialize XML data and may be vulnerable to Denial of Service attacks (DoS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by causing a stackoverflow. This effect may support a denial of service attack.

Vulnerability Details

CVEID:   CVE-2022-40153
DESCRIPTION:   XStream is vulnerable to a denial of service, caused by a stack-based buffer overflow. By sending a specially-crafted XML data, a remote authenticated attacker could exploit this vulnerability to causes the parser to crash, and results in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/236356 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.
