Multiple security issues were discovered in the Rails web framework which could result in cross-site scripting, information leaks, code execution, cross-site request forgery or bypass of upload limits.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A client side enforcement of server side security vulnerability exists in rails < 5.2.4.2 and rails <     6.0.3.1 ActiveStorage's S3 adapter that allows the Content-Length of a direct file upload to be modified     by an end user bypassing upload limits. (CVE-2020-8162)

Note that Nessus relies on the presence of the package as reported by the vendor.
