Full title: SPIP BigUp 4.3.1 / 4.2.15 / 4.1.17 Unauthenticated Remote Code Execution Exploit 
Category: remote exploits
Platform: php
This Metasploit module exploits a Remote Code Execution vulnerability in the BigUp plugin of SPIP. The vulnerability lies in the lister_fichiers_par_champs function, which is triggered when the bigup_retrouver_fichiers parameter is set to any value. By exploiting the improper handling of multipart form data in file uploads, an attacker can inject and execute arbitrary PHP code on the target server. This critical vulnerability affects all versions of SPIP from 4.0 up to and including 4.3.1, 4.2.15, and 4.1.17. It allows unauthenticated users to execute arbitrary code remotely via the public interface. The vulnerability has been patched in versions 4.3.2, 4.2.16, and 4.1.18.
