Sources and claim methodology

  • Source referencedocs.seppmail.com
Upstream source description

SEPPmail Secure Email Gateway before 15.1.1 can evaluate attacker-influenced replacement text as Perl code in sender or recipient replacement rules. An unauthenticated remote sender can execute operating-system commands in the mail-processing worker context when an active rule uses message-derived replacement data and its search condition matches. The validated worker context was root.
