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.

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3956 advisory.

    Package        : smarty3     Version        : 3.1.39-2+deb11u2     CVE ID         : CVE-2018-25047 CVE-2023-28447 CVE-2024-35226     Debian Bug     : 1019897 1033964 1072530

    Multiple vulnerabilties were discovered for smarty3, a widely-used PHP     templating engine, which potentially allows an attacker to perform an     XSS (e.g JavaScript or PHP code injection).

    CVE-2018-25047

        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-2023-28447

        In affected versions smarty did not properly escape javascript code.
        An attacker could exploit this vulnerability to execute arbitrary         JavaScript code in the context of the user's browser session. This         may lead to unauthorized access to sensitive user data, manipulation         of the web application's behavior, or unauthorized actions performed         on behalf of the user. Users are advised to upgrade to either         version 3.1.48 or to 4.3.1 to resolve this issue. There are no known         workarounds for this vulnerability.

    CVE-2024-35226

        In affected versions template authors could inject php code by         choosing a malicious file name for an extends-tag. Sites that cannot         fully trust template authors should update asap. All users are         advised to update.  There is no patch for users on the v3 branch.
        There are no known workarounds for this vulnerability.

    For Debian 11 bullseye, these problems have been fixed in version     3.1.39-2+deb11u2.

    We recommend that you upgrade your smarty3 packages.

    Please note you will have to clear out all smarty generated files after     installing the update, by default in a templates_c directory.

    For the detailed security status of smarty3 please refer to     its security tracker page at:

The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3262 advisory.

  - 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)

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

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)
