Name of the Vulnerable Software and Affected Versions: Microsoft SharePoint Server (affected versions not specified) Microsoft SharePoint Foundation (affected versions not specified) Microsoft SharePoint Enterprise Server (affected versions not specified)

Description: A cross-site-scripting (XSS) issue exists due to the improper sanitization of specially crafted web requests. This could allow an authenticated attacker to perform cross-site scripting attacks, potentially enabling them to read unauthorized content, use the victim's identity to take actions on the SharePoint site, and inject malicious content into the user's browser.

Apply the security update to ensure that SharePoint Server properly sanitizes web requests. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
