phpMyNewsletter lets attackers send emails without admin login

CVE-2007-2372 · published 19 years ago
Summary

The phpMyNewsletter 0.8 beta5 and earlier versions do not stop processing after detecting a missing admin login, letting anyone send messages through the system. An attacker can craft a web request that specifies the email subject, body, format, and list, and then issue a follow‑up request to actually send the email. Update to a newer version or apply a patch that correctly terminates the script when credentials are absent.

admin/send_mod.php in Gregory Kokanosky phpMyNewsletter 0.8 beta5 and earlier prints a Location header but does not exit when administrative credentials are missing, which allows remote attackers to compose an e-mail message via a post with the subject, message, format, and list_id fields; and send the message via a direct request for the MsgId value under admin/.
