AI-analyzed exploit summary This Metasploit module exploits a PHP object deserialization vulnerability in Roundcube Webmail (CVE-2025-49113) to achieve remote code execution. It authenticates as a user, uploads a malicious payload via a crafted `_from` parameter, and executes arbitrary commands as the web server.
Description
Roundcube Webmail before 1.5.10 and 1.6.x before 1.6.11 allows remote code execution by authenticated users because the _from parameter in a URL is not validated in program/actions/settings/upload.php, leading to PHP Object Deserialization.
