Description
If the user is able to add a personal email account (POP3, IMAP, EAS) to the work email app, it could be used to forward sensitive DoD data to unauthorized recipients. Restricting email account addition to the administrator or restricting email account addition to whitelisted accounts mitigates this vulnerability. SFR ID: FMT_SMF_EXT.1.1 #47
