Vulnerability discussion

Acrobat Pro allows for files to be attached to PDF documents. Attachments represent a potential security risk because they can contain malicious content, open other dangerous files, or launch applications.This feature prevents users from opening or launching file types other than PDF or FDF and disables the menu option to re-enable.

Check content

Verify the following registry configuration: Utilizing the Registry Editor, navigate to the following: HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Adobe Acrobat\11.0\FeatureLockDown Value Name: iFileAttachmentPerms Type: REG_DWORD Value: 1 If the value for iFileAttachmentPerms is not set to “1” and Type is not configured to REG_DWORD or does not exist, this is a finding.

Fix text

Configure the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Policies\Adobe\Adobe Acrobat\11.0\FeatureLockDown Value Name: iFileAttachmentPerms Type: REG_DWORD Value: 1

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.
