Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the a8dacd4b-b416-11f0-9f23-ecf4bbefc954 advisory.

PrivateBin reports:
We've identified an HTML injection/XSS vulnerability in the PrivateBin service that allows the injection of arbitrary HTML markup via the attached filename.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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 packages.
