Summary
Lightwell Security Advisory: commons-net 3.6.0.rhlw-00001
Details

Red Hat Lightwell has released commons-net:commons-net 3.6.0.rhlw-00001 with a backported security fix.

CVE-2021-37533: Prior to Apache Commons Net 3.9.0, Net's FTP client trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client. The default in version 3.9.0 is now false to ignore such hosts, as cURL does. See https://issues.apache.org/jira/browse/NET-711.

This patched artifact is a drop-in replacement for commons-net:commons-net 3.6.0 from Maven Central.
