Technical details
The vulnerability exists in the mailbox action feature where MIME parts of incoming emails are saved to the web-accessible directory media/com_acym/upload/ without file extension validation. An attacker with access to a monitored mailbox can craft emails containing PHP files that will be extracted and written to the web root, enabling remote code execution. No authentication is required beyond ability to send email to the configured mailbox.
