Produsentens beskrivelse (engelsk)

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.
