2.2.24 Ensure 'Modify an object label' is set to 'No One'

Information

This privilege determines which user accounts can modify the integrity label of objects, such as files, registry keys, or processes owned by other users. Processes running under a user account can modify the label of an object owned by that user to a lower level without this privilege.

The recommended state for this setting is: No One.

Rationale:

By modifying the integrity label of an object owned by another user a malicious user may cause them to execute code at a higher level of privilege than intended.

Impact:

None - this is the default behavior.

Solution

To establish the recommended configuration, set the following Device Configuration Policy to No one:

To access the Device Configuration Policy from the Intune Home page:

Click Devices

Click Configuration profiles

Click Create profile

Select the platform (Windows 10 and later)

Select the profile (Endpoint protection)

Click Create

Enter a Name

Click Next

Configure the following Setting

Path: Endpoint protection/User Rights
Setting Name: Modify an object label
Configuration: No One <Blank>

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.

Note #2: This setting can also be created via a Custom Configuration Profile using the following OMA-URI:

Name: <Enter name>
Description: <Enter Description>
OMA-URI: ./Device/Vendor/MSFT/Policy/Config/UserRights/ModifyObjectLabel
Data type: String
Value: No One <Blank>

Important: When there is more than one value that needs to be entered (ex: Guests, Administrator), the XML value of will need to be converted to US-ASCII to separate the values in the Value field of the Custom Device Configuration Policy. This value should convert to a square with a question mark in it (). Please note that when copied from the converter to Intune a square will appear, but the value will still work. Also note that this value cannot be copied from sources like Microsoft Word. We recommend that the value be copied and used directly from the converter.

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note #3: The following link is an alternative way to set the 'User Rights Assignment' section. Policy CSP - UserRights - Windows Client Management | Microsoft Docs

Default Value:

No one.
