An authenticated Email Protection Gateway administrator holding only limited, delegated permissions could write files with attacker-controlled content to arbitrary locations accessible to the Email Protection Gateway service account.

MEDIUM 6.5EPSS 1.01%

Does this matter?

Lower severity and a low EPSS score (1.01%). Track it; it rarely justifies an emergency change on its own.

Description

An authenticated Email Protection Gateway administrator holding only limited, delegated permissions could write files with attacker-controlled content to arbitrary locations accessible to the Email Protection Gateway service account. This exceeds the administrator's intended privileges and could be used to alter application files and configuration or to disrupt the availability of the service.
