XSL PHP V
This exercise covers the exploitation of a PHP application using XSL
In this challenge, we delve into Extensible Stylesheet Language (XSL) and its potential to trigger unexpected behaviors in PHP applications. Your goal is to gain command execution by discovering and using a specific native PHP function enabled within the application. Initially, you'll upload a payload to read the application's source code, revealing the PHP function you can exploit.
Once the function is identified, you will leverage it to execute commands. Specifically, you will use the xsl:variable tag to manage complex command structures more effectively. This method bypasses the need for cumbersome encoding, simplifying the process of gaining command execution. Through these steps, you will gain a deeper understanding of how XSL can be manipulated to interact with PHP functions and achieve code execution.
