"The remote host is affected by the vulnerability described in GLSA-202209-09 (Smarty: Multiple vulnerabilities)

  - In Smarty before 3.1.47 and 4.x before 4.2.1, libs/plugins/function.mailto.php allows XSS. A web page that
    uses smarty_function_mailto, and that could be parameterized using GET or POST input parameters, could
    allow injection of JavaScript code by a user. (CVE-2018-25047)

  - 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 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)

  - Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from
    application logic. Prior to versions 3.1.45 and 4.1.1, template authors could inject php code by choosing
    a malicious {block} name or {include} file name. Sites that cannot fully trust template authors should
    upgrade to versions 3.1.45 or 4.1.1 to receive a patch for this issue. There are currently no known
    workarounds. (CVE-2022-29221)

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