path wizards/post2file.php↗

• → Monitor for unauthenticated POST requests to wizards/post2file.php, especially those containing PHP file content in the request body, as this is the vulnerable upload endpoint. ↗
• → Alert on PHP files appearing in the webroot of Idera Up.Time Monitoring Station (versions ≤7.2) that were not part of the original installation, as successful exploitation drops a PHP webshell there. ↗
• → The Metasploit module exploits/multi/http/uptime_file_upload_1 targets this vulnerability; presence of this module string in logs or network traffic indicates active exploitation attempts. ↗
