Security Bulletin: Vulnerability in Apache Log4j affects IBM Spectrum Archive Enterprise Edition (CVE-2021-44228)


## Summary A vulnerability in Apache Log4j could allow an attacker to execute arbitrary code on the system. This vulnerability may affect the IBM Spectrum Archive Enterprise Edition (EE). The below fix package includes Apache Log4j 2.15. ## Vulnerability Details ** CVEID: **[CVE-2021-44228](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44228>) ** DESCRIPTION: **Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the failure to protect against attacker controlled LDAP and other JNDI related endpoints by JNDI features. By sending a specially crafted code string, an attacker could exploit this vulnerability to load arbitrary Java code on the server and take complete control of the system. Note: The vulnerability is also called Log4Shell or LogJam. CVSS Base score: 10 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/214921](<https://exchange.xforce.ibmcloud.com/vulnerabilities/214921>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) ## Affected Products and Versions Affected Product(s)| Version(s) ---|--- Enterprise Edition| - ## Remediation/Fixes IBM strongly recommends addressing this vulnerability now by upgrading. **Note: The below fix package includes Log4j 2.15.** Affected Versions| Fixing Level| Platform ---|---|---|| Linux Refer to the instructions in the Workarounds and Mitigations section for Log4j in the optional third party open source software, Elasticsearch and Logstash. Based on current analysis and information, IBM Spectrum Archive Library Edition (LE) and Single Drive Edition (SDE) are not affected. ## Workarounds and Mitigations **IBM strongly recommends addressing the vulnerability now by executing these manual steps, for Log4j in Elasticsearch and Logstash. ** IBM Spectrum Archive Enterprise Edition includes three dependent software which include the version of Apache Log4j with the vulnerability described in CVE-2021-44228. They are * HSM Component in IBM Spectrum Archive Enterprise Edition Log4j 2.13.3 * Elasticsearch 5.6.8 in IBM Spectrum Archive Enterprise Edition Log4j 2.9.1 * Logstash 5.6.8 in IBM Spectrum Archive Enterprise Edition Log4j 2.6.2 HSM component is always installed by the default installation procedure of IBM Spectrum Archive Enterprise Edition, and Elasticsearch and Logstash RPMs are manually installed when the dashboard function is needed. **Fix for Log4j shipped with HSM component** Upgrade to the version described in Remediation/Fixes section. **Mitigation for Log4j bundled in Elasticsearch and Logstash** Logstash is typically installed under /usr/share/logstash directory on all IBM Spectrum Archive nodes when the dashboard function is used, and Elasticsearch is installed under /usr/share/elasticsearch directory on external monitoring server. Per the Apache Log4j security vulnerability advisory, find the Log4j jar files under those installation directories, and remove the JndiLookup class from the jar files by: `zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class `See the security announcements and detailed instructions from Elastic for removing JndiLookup from relevant JAR files​. ## Get Notified about Future Security Bulletins Subscribe to [My Notifications](< http://www-01.ibm.com/software/support/einfo.html>) to be notified of important product support alerts like this. ### References [Complete CVSS v3 Guide](<http://www.first.org/cvss/user-guide> "Link resides outside of ibm.com" ) [On-line Calculator v3](<http://www.first.org/cvss/calculator/3.0> "Link resides outside of ibm.com" ) Off ## Related Information [IBM Secure Engineering Web Portal](<http://www.ibm.com/security/secure-engineering/bulletins.html>) [IBM Product Security Incident Response Blog](<http://www.ibm.com/blogs/psirt>) ## Acknowledgement ## Change History 16 Dec 2021: Initial Publication 12 Jan 2022: Updated Remediation/Fixes section, with the fixing level *The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score.
