Smarty before 3.1.39 allows a Sandbox Escape because $smarty.template_object can be accessed in sandbox mode.

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5348-2 advisory.

  - Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from     application logic. Prior to versions 3.1.43 and 4.0.3, template authors could run restricted static php     methods. Users should upgrade to version 3.1.43 or 4.0.3 to receive a patch. (CVE-2021-21408)

  - Smarty before 3.1.39 allows a Sandbox Escape because $smarty.template_object can be accessed in sandbox     mode. (CVE-2021-26119)

  - Smarty before 3.1.39 allows code injection via an unexpected function name after a {function name=     substring. (CVE-2021-26120)

  - Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from     application logic. Prior to versions 3.1.42 and 4.0.2, template authors could run arbitrary PHP code by     crafting a malicious math string. If a math string was passed through as user provided data to the math     function, external users could run arbitrary PHP code by crafting a malicious math string. Users should     upgrade to version 3.1.42 or 4.0.2 to receive a patch. (CVE-2021-29454)

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