The Classics Return: Vulnerable E-Mail Scripts
Honeypot monitoring has detected increased scanning activity targeting email scripts on web servers, with attackers probing for test and development email scripts left on production systems. The scans target common filenames such as sendmail.php, test-mail.php, and mailtest.php, likely seeking scripts that allow arbitrary "To" headers for spam abuse or exposed server configuration data. The underlying issue is poor code hygiene: development artifacts and test scripts should never reach live environments, as illustrated by publicly discoverable examples that include unfiltered email parameters and environment variable disclosure.
Why it matters: Web administrators and developers should audit production systems for test or development email scripts that could enable spam relay or information disclosure; attackers are actively scanning for these overlooked files.
