Plesk 8.6.0, when short mail login names (SHORTNAMES) are enabled, allows remote attackers to bypass authentication and send spam e-mail via a message with (1) a base64-encoded username that begins with a valid shortname, or (2) a username that matches a valid password, as demonstrated using (a) SMTP and qmail, and (b) Courier IMAP and POP3.

Security readout for executives and security teams

CVE-2008-6984 affects Plesk 8.6.0 systems where short mail login names are enabled. An unauthenticated remote attacker could bypass mail authentication and use the server to send spam. Business risk is mainly abuse of mail infrastructure, domain reputation damage, and possible access to virtual mail user privileges. Exposure appears limited to Plesk 8.6.0 deployments with SHORTNAMES enabled and mail services reachable remotely. The source bundle does not identify other affected versions, platforms, or CPEs. Prioritize if legacy Plesk 8.6.0 mail servers remain internet-facing. The risk is high for affected systems, but scope is narrow and evidence of active exploitation is not provided. Mitigation focus: Identify any Plesk 8.6.0 servers still operating mail services.; If supported, disable short mail login names until vendor guidance is confirmed.; Check Plesk vendor or historical support guidance for fixed versions or configuration workarounds..
