CVE-2021-45105 Apache Log4j Vulnerability in NetApp Products

Summary

Multiple NetApp products incorporate Apache Log4j. Apache Log4j versions 2.0-alpha1 through 2.16.0 did not protect from uncontrolled recursion from self-referential lookups. Versions prior to 2.17.0 are susceptible to a vulnerability when the logging configuration uses a non-default Pattern Layout with a Context Lookup. When successfully exploited this could allow attackers with control over Thread Context Map (MDC) input data to craft malicious input data that contains a recursive lookup, resulting in a StackOverflowError that will terminate the process.

Impact

Successful exploitation of this vulnerability could lead to Denial of Service (DoS).

NetApp SolidFire, Enterprise SDS & HCI Storage Node (Element Software) is affected only when the “Virtual Volumes (vVols)” feature is enabled on the cluster.

Software Versions and Fixes

NetApp's currently available patches are listed below.


Product First Fixed in Release
Cloud Manager
This issue is fixed and auto-remediated. Cloud Manager instances with the Auto-upgrade setting enabled should have updated on 20220102 to the fixed version 3.9.14 build4. No further action is required.

Cloud Manager instances with the Auto-upgrade setting disabled should follow the steps below to enable it to receive the fixed version.
1. Connect to the Cloud Manager command line using SSH.
2. Run "sudo -s".
3. Navigate to the app.conf location - note that the file could be in varying locations per Cloud Manager version. Use “find . -name app.conf” to locate it.
4. Create a backup of the app.conf file.
5. Edit the app.conf file and change the "auto-upgrade" flag from "false" to "true".
6. Save the file and then restart the Cloud Manager instance.
7. Once the instance is back up visit the Cloud Manager UI to confirm that the version is now 3.9.14 or higher.
