An information disclosure vulnerability exists when Microsoft SharePoint Server improperly discloses its folder structure when rendering specific web pages. An attacker who took advantage of this information disclosure could view the folder path of scripts loaded on the page.

To take advantage of the vulnerability, an attacker would require access to the specific SharePoint page affected by this vulnerability.

The security update addresses the vulnerability by correcting how scripts are referenced on some SharePoint pages.
