Hello,

 

I wanted to ask if there's a page / instructions / info regarding the recent log4j2 vulnerability (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44228) and how it can affect Cloudera CDH setups? If it does affect, what are the recommended mitigations on it?

 

Thanks,

Mor

I second this question. I currently administer a CDH 5.16 cluster that we're in the process of upgrading to CDP 7.x. Is there a statement from cloudera about the extent of the vulnerablility in their products and how we can go about patching it?
