[R1] Tenable Plugin Feed ID #202212081952 Fixes Arbitrary Code Execution
Vulnerability
Critical
Synopsis
Audit files that are built into the Tenable products provide capability to
adjust the audit evaluation to meet organizational requirements. A
vulnerability was reported where through modifying the scan variables, an
authenticated user in Tenable products, that has Scan Policy Configuration
roles, could manipulate audit policy variables to execute arbitrary commands on
credentialed scan targets.
CVE-2022-4313
This vulnerability only includes built-in audits that are selected through the
product interfaces. It does not include custom audits that are uploaded by the
customer.
Solution
Tenable has released updated compliance plugins and audit files that will
validate customer entered values against defined variable types. The plugins
have been distributed via the Tenable plugin feed 202212081952 or later. Audits
have been distributed to the products through the standard channels with the
following notes:
Tenable.io has been updated with the plugins and content necessary to remediate
this vulnerability.
Tenable.sc updates are distributed in the feed and activated when the customer
uses the new template.
Nessus version 10.4.2 or later will have the updated audit content.
Users of earlier versions can perform a manual update of the audit warehouse to
obtain the content. Please refer to the additional resources below for more
information.
