Froxlor is open source server administration software. Prior to version 2.3.6, in , the domain ownership validation for full email sender aliases uses the wrong array index when splitting the email address, passing the local part instead of the domain to . This causes the ownership check to always pass for non-existent "domains," allowing any authenticated customer to add sender aliases for email addresses on domains belonging to other customers. Postfix's then authorizes the attacker to send emails as those addresses. Version 2.3.6 fixes the issue.
