Vulnerability discussion

Protected Mode is a “sandbox” that is essentially a read-only mode. When enabled, Acrobat allows the execution environment of untrusted PDF's and the processes the PDF may invoke but also presumes all PDFs are potentially malicious and confines processing to a restricted sandbox.

Check content

Verify the following registry configuration: Using the Registry Editor, navigate to the following: HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown Value Name: bProtectedMode Type: REG_DWORD Value: 1 If the value for bProtectedMode is not set to “1” and Type is not configured to REG_DWORD or does not exist, this is a finding. Admin Template path: Computer Configuration > Administrative Templates > Adobe Acrobat Pro DC Continuous > Preferences > 'Protected Mode' must be set to 'Enabled'.

"AcrobatProDCContinuous.admx" and "AcrobatProDCContinuous.adml" must be copied to the \Windows\PolicyDefinitions and \Windows\PolicyDefinitions\en-US directories respectively.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
