Loading vulnerability…
The tiki-graph_formula.php script in TikiWiki 1.9.8 is vulnerable to remote code execution due to improper handling of user-supplied input in the 'f' array parameter. The input is passed directly to PHP's create_function, allowing attackers to inject and execute arbitrary PHP code on the server.

This repository contains a single Metasploit module (modules/exploits/unix/webapp/tikiwiki_graph_formula_exec.rb) targeting a remote code execution vulnerability in TikiWiki (<= 1.9.8), specifically in the tiki-graph_formula.php script. The exploit leverages improper input sanitization in the 'f' parameter, allowing attackers to execute arbitrary PHP code via crafted HTTP requests. The module first checks if the target is running a vulnerable version of TikiWiki by querying tiki-index.php. Upon exploitation, it attempts to read the db/local.php file to extract database credentials and then executes a user-supplied PHP payload, which can be used for further compromise (e.g., reverse shell, Meterpreter). The exploit is operational, providing real code execution and credential extraction capabilities. The main attack vector is network-based, exploiting a web application endpoint. The repository is structured as a standard Metasploit module, written in Ruby, and is intended for use within the Metasploit Framework.
