Title
Empty initial password permits GINA account takeover
Summary
SEPPmail Secure Email Gateway before 15.1.1 permits password recovery for a created but unregistered GINA account whose initial password is empty without adequately verifying ownership. A remote unauthenticated attacker who identifies such an account can set a new password, authenticate as that account, and prevent the intended recipient from using it until recovery.

Title
Pre-authentication upload parsing permits resource exhaustion
Summary
SEPPmail Secure Email Gateway before 15.1.1 processes and writes v1 file-interface upload data before authenticating the caller and without an absolute request-size limit. An unauthenticated remote attacker can occupy workers and consume temporary storage with concurrent or slow requests, causing service unavailability.

Summary
SEPPmail Secure Email Gateway before 15.1.1 trusts a file path supplied in externally provided Large File Transfer attachment metadata. An unauthenticated remote sender can cause the mail-processing worker to disclose, move, or delete an accessible regular file when LFT is enabled and the message reaches an affected secure-mail processing path. The validated workers ran as root.

Title
Code execution through double evaluation in address replacement rules
Summary
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.
