CVE-2012-0911 is an unsafe deserialization vulnerability in TikiWiki CMS/Groupware before 6.7 LTS and before 8.4. Multiple request-controlled values, including a cookie value and page-printing or object-sending parameters, are passed to PHP's unserialize() without adequate validation or integrity protection. An attacker can supply a crafted serialized object and invoke application-defined PHP object behaviors during deserialization, enabling arbitrary PHP code execution.

This repository contains a single Metasploit module (Ruby file) that exploits a PHP unserialize() vulnerability (CVE-2012-0911) in Tiki Wiki versions 8.3 and below. The exploit targets the 'tiki-print_multi_pages.php' script, abusing the 'printpages' POST parameter to trigger a PHP object injection via crafted serialized data. The module first discloses the filesystem path using 'tiki-rss_error.php' (requiring 'display_errors' to be enabled), then uploads a PHP webshell to the server by exploiting the unserialize() flaw, and finally executes arbitrary PHP code by sending a base64-encoded payload in the 'Cmd' HTTP header to the uploaded webshell. The exploit is weaponized, allowing for customizable payloads and session cleanup. The only file present is the Metasploit module itself, written in Ruby, and it leverages the Metasploit framework's HTTP client and payload handling capabilities.
