Security Bulletin

Summary

IBM QRadar SIEM is affected by arbitrary code execution due to Apache Log4j CVE-2019-17571, CVE-2021-44832, CVE-2021-4104. Apache Log4j is used by IBM QRadar SIEM as part of its logging infrastructure. The fix includes Apache Log4j 2.17.2

Vulnerability Details

CVEID: CVE-2019-17571
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by improper deserialization of untrusted data in SocketServer. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/173314 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2021-44832
DESCRIPTION: Apache Log4j could allow a remote attacker with permission to modify the logging configuration file to execute arbitrary code on the system. By constructing a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI , an attacker could exploit this vulnerability to execute remote code.
CVSS Base score: 6.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216189 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2021-4104
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the deserialization of untrusted data when the attacker has write access to the Log4j configuration. If the deployed application is configured to use JMSAppender, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215048 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

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.
