Discussion

Flash content is commonly hosted on a web page, but it can also be embedded in PDF and other documents. Flash could be used to surreptitious install malware on the end-users computer. Flash Content restricts Adobe Reader DC not to play Flash content within a PDF. 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: bEnableFlash
Type: REG_DWORD
Value: 0

If the value for bEnableFlash is not set to “0” and Type configured to REG_DWORD or does not exist, then this is a finding.

Registry Hive: HKEY_LOCAL_MACHINE
