Security Bulletin
Summary
Apache Log4j is used by IBM Cognos Controller as part of its logging infrastructure. This bulletin addresses the exposure to the Apache Log4j vulnerabilities (CVE-2022-23305, CVE-2022-23302, CVE-2021-4104). Although IBM Cognos Controller is not vulnerable to the listed CVEs, all instances of Apache Log4j v1.x were proactively upgraded to Apache Log4j v2.17.1 for the IBM Cognos Controller 10.4.2 and 10.4.1 streams.
Vulnerability Details
CVEID: CVE-2022-23305
DESCRIPTION: Apache Log4j is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements to the JDBCAppender, which could allow the attacker to view, add, modify or delete information in the back-end database.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217461 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2022-23302
DESCRIPTION: Apache Log4j could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unsafe deserialization in JMSSink. By sending specially-crafted JNDI requests using TopicConnectionFactoryBindingName configuration, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217460 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/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)
