Security Bulletin: IBM WebSphere Application Server and IBM WebSphere Application Server Liberty are vulnerable to arbitrary code execution and SQL injection due to Apache Log4j. (CVE-2022-23302, CVE-2022-23307, CVE-2022-23305)

Summary

Multiple vulnerabilities exist in the Apache Log4j (CVE-2022-23302, CVE-2022-23305, CVE-2022-23307) library used by IBM WebSphere Application Server in the Admin Console and UDDI Registry application. The same Apache library is also used by the IBM WebSphere Application Server Liberty for z/OS in features zosConnect-1.0 and zosConnect-1.2. All vulnerabilities have been addressed previously by removing all existing Apache Log4j versions.

Vulnerability Details

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-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-2022-23307
**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.

Affected Products and Versions

Remediation/Fixes

IBM strongly recommends addressing the vulnerabilities now by applying a currently available interim fix or fix pack that contains APAR PH42762. The interim fix PH42762 was provided previously with Security Bulletin: Multiple vulnerabilities in Apache log4j affect the IBM WebSphere Application Server and IBM WebSphere Application Server Liberty (CVE-2021-4104, CVE-2021-45046) and the interim fix PH42762 addresses these vulnerabilities for the affected IBM WebSphere Application Server and IBM WebSphere Application Server Liberty.

For IBM WebSphere Application Server Liberty 17.0.0.3 - 21.0.0.12 using the zosConnect-1.0 or zosConnect-1.2 feature:

· Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PH42762
--OR–
· Apply Fix Pack 22.0.0.1 or later.

For IBM WebSphere Application Server traditional:

For V9.0.0.0 through 9.0.5.10:
· Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PH42762
--OR–
· Apply Fix Pack 9.0.5.11 or later (when available).

For V8.5.0.0 through 8.5.5.20:
· Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PH42762
--OR–
· Apply Fix Pack 8.5.5.21 or later (when available).

For V8.0.0.0 through 8.0.0.15:
· Upgrade to 8.0.0.15 and then apply Interim Fix PH42762

For V7.0.0.0 through 7.0.0.45:
· Upgrade to 7.0.0.45 and then apply Interim Fix PH42762

Additional interim fixes may be available and linked off the interim fix download page.

After applying the interim fix, follow the Required next steps provided previously with Security Bulletin: Multiple vulnerabilities in Apache log4j affect the IBM WebSphere Application Server and IBM WebSphere Application Server Liberty (CVE-2021-4104, CVE-2021-45046)

IBM WebSphere Application Server V7.0 and V8.0 are no longer in full support; IBM recommends upgrading to a fixed, supported version/release/platform of the product.

Workarounds and Mitigations

If the interim fixes in PH42762 cannot be applied immediately, and the mitigation steps have not been applied previously for Security Bulletin: Multiple vulnerabilities in Apache log4j affect the IBM WebSphere Application Server and IBM WebSphere Application Server Liberty (CVE-2021-4104, CVE-2021-45046), then follow the temporary mitigation steps for WebSphere Application Server traditional in Security Bulletin: Multiple vulnerabilities in Apache log4j affect the IBM WebSphere Application Server and IBM WebSphere Application Server Liberty (CVE-2021-4104, CVE-2021-45046). Due to the severity, complexity, and evolving nature of the situation, no mitigation is recommended as a substitute for applying the interim fix.
