Handlebars before 3.0.8 and 4.x before 4.5.3 is vulnerable to Arbitrary Code Execution. The lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript. This can be used to run arbitrary code on a server processing Handlebars templates or in a victim's browser (effectively serving as XSS).

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Handlebars before 3.0.8 and 4.x before 4.5.3 is vulnerable to Arbitrary Code Execution. The lookup helper
    fails to properly validate templates, allowing attackers to submit templates that execute arbitrary
    JavaScript. This can be used to run arbitrary code on a server processing Handlebars templates or in a
    victim's browser (effectively serving as XSS). (CVE-2019-20920)

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

  - Handlebars before 3.0.8 and 4.x before 4.5.3 is vulnerable to Arbitrary Code Execution. The lookup helper     fails to properly validate templates, allowing attackers to submit templates that execute arbitrary     JavaScript. This can be used to run arbitrary code on a server processing Handlebars templates or in a     victim's browser (effectively serving as XSS). (CVE-2019-20920)

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

According to its self-reported version number, HandlebarsJS on the remote server is prior to 3.0.8 or 4.x prior to 4.5.3. Therefore, it may be affected by a arbitrary code execution vulnerability permitting attackers to submit templates that execute aribtrary Javascript either server-side on a server processing Handlebars templates, or in a victims browser.

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5179 advisory.

    The org.ovirt.engine-root is a core component of oVirt.

    The following packages have been upgraded to a later upstream version: engine-db-query (1.6.2),     org.ovirt.engine-root (4.4.3.8), ovirt-engine-dwh (4.4.3.1), ovirt-engine-extension-aaa-ldap (1.4.2),     ovirt-engine-extension-logger-log4j (1.1.1), ovirt-engine-metrics (1.4.2.1), ovirt-engine-ui-extensions     (1.2.4), ovirt-log-collector (4.4.4), ovirt-web-ui (1.6.5), rhv-log-collector-analyzer (1.0.5), rhvm-     branding-rhv (4.4.6).
