Background
Smarty3 is a popular template engine for PHP. It is widely used to separate the presentation layer from the business logic in web applications. It provides a simple and efficient way to generate dynamic web pages by allowing developers to define templates with placeholders that are filled with data at runtime. However, a security vulnerability has been discovered in smarty3 that allows remote attackers to bypass secure mode restrictions and execute arbitrary PHP code.
Vulnerability Detail
The vulnerability in smarty3 allows an attacker to inject malicious PHP code into a template, which is then executed by the server. This can lead to various security issues, including remote code execution, data leakage, and unauthorized access to sensitive information. The vulnerability is triggered when the attacker includes the "{literal}<{/literal}script language=php>" code in a template. This code is not properly sanitized by smarty3, allowing it to be executed as PHP code on the server.
