Vulnerability discussion

The auto-fill functionality in the web browser allows the user to complete a form that contains sensitive information, such as personally identifiable information (PII), without previous knowledge of the information. By allowing the use of auto-fill functionality, an adversary who learns a user's mobile operating system device password, or who otherwise is able to unlock the device, may be able to further breach other systems by relying on the auto-fill feature to provide information unknown to the adversary. By disabling the auto-fill functionality, the risk of an adversary gaining further information about the device's user or compromising other systems is significantly mitigated.SFR ID: FMT_SMF_EXT.1.1 #45

Check content

This validation procedure is performed on both the MDM Administration Console and the Samsung KNOX for Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow browser auto-fill" setting in the "Android KNOX Container >> Container Restrictions" rule. 2. Verify the setting is disabled. On the Samsung KNOX for Android device: 1. Open the KNOX container. 2. Launch the browser application. 3. Select the application's setting menu. 4. Select "Auto fill profile". 5. Select "Auto fill profile" and attempt to create a profile. 6. Select "Privacy" from the setting menu. 7. Attempt to enable "Save sign-in info". If the "Allow browser auto-fill" configuration in the MDM console is enabled, or if the user is able to successfully create a profile or enable "Save sign-in info", this is a finding.

Fix text

Configure the mobile operating system to disable browser auto-fill for the container browser application. On the MDM Administration Console, disable the "Allow browser auto-fill" setting in the "Android KNOX Container >> Container Restrictions" rule.

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.
