The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0212 advisory.

    Red Hat CloudForms Management Engine delivers the insight, control, and automation needed to address the     challenges of managing virtual environments. CloudForms Management Engine is built on Ruby on Rails, a     model-view-controller (MVC) framework for web application development. Action Pack implements the     controller and the view components.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

OSS-Security list :

There is a possible XSS vulnerability in rails-html-sanitizer. The gem allows non-whitelisted attributes to be present in sanitized output when input with specially crafted HTML fragments, and these attributes can lead to an XSS attack on target applications.

This issue is similar to CVE-2018-8048 in Loofah.

OSS-Securityリスト：

rails-html-sanitizerにXSSの脆弱性がある可能性があります。gemでは、特別に細工されたHTMLフラグメントを入力する際のサニタイズされた出力に、ホワイトリストに登録されていない属性が存在する可能性があり、これらの属性が、ターゲットアプリケーションに対するXSS攻撃を引き起こす可能性があります。

この問題はLoofahにおけるCVE-2018-8048と類似しています。
