Discussion

Attachments represent a potential security risk because they can contain malicious content, open other dangerous files, or launch applications. Certainly file types such as .bin, .exe, .bat, and so on will be recognized as threats. This feature prevents users from opening or launching file types other than PDF or FDF and disables the menu option. Satisfies: SRG-APP-000112, SRG-APP-000206, SRG-APP-000207, SRG-APP-000209, SRG-APP-000210

Check Content

Verify the following registry configuration:

Utilizing the Registry Editor, navigate to the following: HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown

Value Name: iFileAttachmentPerms
Type: REG_DWORD

If the value for iFileAttachmentPerms is not set to “1” and Type configured to REG_DWORD or does not exist, then this is a finding.
