Security Bulletin
Summary
DS8000 Hardware Management Console which consumes Log4j, is subject to CVE-2021-45105 which could cause a denial of service and CVE-2021-45046 which could cause the leak of sensitive information and remote code execution in some environments and local code execution in all environments. IBM strongly recommends addressing the vulnerability now by applying the fix below.
Vulnerability Details
CVEID: CVE-2021-45105
DESCRIPTION: Apache Log4j is vulnerable to a denial of service, caused by the failure to protect from uncontrolled recursion from self-referential lookups. A remote attacker with control over Thread Context Map (MDC) input data could craft malicious input data that contains a recursive lookup to cause a StackOverflowError that will terminate the process.
Note: The vulnerability is also called LOG4J2-3230.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215647 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2021-45046
DESCRIPTION: Apache Log4j could result in remote code execution, caused by an incomplete fix of CVE-2021-44228 in certain non-default configurations. When the logging configuration uses a non-default Pattern Layout with a Context Lookup, an attacker with control over Thread Context Map (MDC) input data can craft malicious input data using a JNDI Lookup pattern to leak sensitive information and remote code execution in some environments and local code execution in all environments.
CVSS Base score: 9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215195 for the current score.

Remediation/Fixes
IBM strongly recommends addressing the vulnerability now.
NOTE: The remediation is the same as for CVE_2021_44228 and customers who have already applied ICS CVE_2021_44228_v1.0, do NOT need to re-apply this ICS. For details please see https://www.ibm.com/support/pages/node/6528280.
All versions of the DS89000F and DS8880 are potentially impacted. Customers should either schedule Remote Code Load (RCL) via https://www.ibm.com/support/pages/ibm-remote-code-load or contact IBM support, and request that ICS CVE_2021_44228_v1.0 or CVE_2021_44228_v1.1 be applied to their systems
DS8900F systems at release 9.0 are impacted and must upgrade to R9.1 or above
- DS8900F systems below R9.1 SP 2 (89.12.8.0) must update to at least 89.12.8.0, and preferably to at least the recommend release (89.13.7.0 or 89.21.28.) before applying the ICS which updates the Log4j package to v2.17.0.
- DS8880 systems below R8.5 GA2 - (88.50.184.0) must update to at least 88.50.184.0 and preferably to at least the recommended release (88.58.3.0) before applying the ICS which updates the Log4j package to v2.17.0.
For the current recommended code releases, please see https://www.ibm.com/support/pages/ds8000-code-recommendation
