Security Bulletin: Crypto Hardware Initialization and Maintenance is vulnerable to arbitrary code execution due to Apache Log4j (CVE 2021-4104, CVE 2022-23302, CVE 2022-23305, CVE 2022-23307)

Summary

Crypto Hardware Initialization and Maintenance (CHIM) as shipped with IBM Common Cryptographic Architecture (CCA) for MTM 4767 is affected by several vulnerabilities in Apache Log4j (CVE-2021-4104, CVE-2022-23303, CVE 2022-23305 and CVE 2022-23307). CHIM is using Apache Log4j for internal logging purposes of regular user activity. The fix includes Apache Log4j 2.17.1.

Vulnerability Details

CVEID:CVE-2022-23307
**DESCRIPTION:**Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization in the in Apache Chainsaw component. By sending specially-crafted input, 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/217462 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-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.

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.

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.

Affected Products and Versions

Remediation/Fixes

IBM strongly recommends addressing the vulnerability now by upgrading:

CHIM is bundled with CCA for MTM 4767 for Linux x64 and is a graphical tool used for initializing and configuring CCA.

The fixed version can be obtained from the CCA Software Download Page.
