Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS : Apache Commons Net vulnerability (USN-6037-1)

medium Nessus Plugin ID 174751

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 host has a package installed that is affected by a vulnerability as referenced in the USN-6037-1 advisory.

 - 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. (CVE-2021-37533)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libcommons-net-java package.
