Vulnerability discussion

When directory service data files, especially for directories used for identification, authentication, or authorization, reside on the same logical partition as user-owned files, the directory service data may be more vulnerable to unauthorized access or other availability compromises. Directory service and user-owned data files sharing a partition may be configured with less restrictive permissions in order to allow access to the user data. The directory service may be vulnerable to a denial of service attack when user-owned files on a common partition are expanded to an extent preventing the directory service from acquiring more space for directory or audit data.

Check content

Refer to the AD database location obtained in check V-8316. Note the logical drive (e.g., C:) on which the files are located. Determine if the server is currently providing file sharing services to users with the following command. Enter "net share" at a command prompt. Note the logical drive(s) or file system partition for any site-created data shares. Ignore all system shares (e.g., Windows NETLOGON, SYSVOL, and administrative shares ending in $). User shares that are hidden (ending with $) should not be ignored. If user shares are located on the same logical partition as the directory server data files, this is a finding.

Fix text

Ensure files owned by users are stored on a different logical partition then the directory server data files.

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.
