Vulnerability discussion

Unsecure Bluetooth profiles may allow either unauthenticated connections to mobile devices or transfer of sensitive DoD data without required DoD information assurance (IA) controls. Only the HSP and HFP profiles are required to meet current DoD Bluetooth needs and DoD data and voice IA controls.SFR ID: FMT_SMF.1.1 #42

Check content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow Bluetooth File Transfer" setting in the MDM console. 2. Verify the Bluetooth File transfer (pbap, ftp, opp, sap, hdp, gatt, map), Network(pan) and HID(hid) settings for the Bluetooth Profile are disabled. On the LG Android device: 1. Unlock the device 2. Open the device settings. 3. Navigate to the Bluetooth setting: Settings >> Bluetooth 4. Pair with the other device. 5. Try to send files (for example, a photo) to paired device. 6. Verify sending files failed and the following message is displayed: Bluetooth is disabled by server policy. If the Bluetooth File transfer(pbap, ftp, opp, sap, hdp, gatt, map), Network (pan) and HID(hid) profiles are not disabled in the "Allow Bluetooth Profiles" setting, or if the user is able to send data files via these Bluetooth profiles on the device, this is a finding.

Fix text

Configure the mobile device to disable Bluetooth Profiles. On the MDM Administration Console, set the "Allow Bluetooth Profile" to disable File transfer, Network, and HID Profiles.

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.
