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)

    It was discovered that Smarty was incorrectly sanitizing the paths present in the templates. An attacker     could possibly use this use to read arbitrary files when controlling the executed template.
    (CVE-2018-16831)

    It was discovered that Smarty was incorrectly validating security policy data, allowing the execution of     static classes even when not permitted by the security settings. An attacker could possibly use this issue     to execute arbitrary code. (CVE-2021-21408)

    It was discovered that Smarty was incorrectly managing access control to template objects, which allowed     users to perform a sandbox escape. An attacker could possibly use this issue to send specially crafted     input to applications that use Smarty and execute arbitrary code. (CVE-2021-26119)

    It was discovered that Smarty was not checking for special characters when setting function names during     plugin compile operations. An attacker could possibly use this issue to send specially crafted input to     applications that use Smarty and execute arbitrary code. (CVE-2021-26120)

    It was discovered that Smarty was incorrectly sanitizing characters in math strings processed by the math     function. An attacker could possibly use this issue to send specially crafted input to applications that     use Smarty and execute arbitrary code. (CVE-2021-29454)
