CVE-2022-29221

Status Candidate

Overview

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.

Posted May 28, 2022
Authored by Debian | Site debian.org

Debian Linux Security Advisory 5151-1 - Several security vulnerabilities have been discovered in smarty3, the compiling PHP template engine. Template authors are able to run restricted static php methods or even arbitrary PHP code by crafting a malicious math string or by choosing an invalid {block} or {include} file name. If a math string was passed through as user provided data to the math function, remote users were able to run arbitrary PHP code as well.
