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

Description The issue is related to a cross-site scripting (XSS) attack, which occurs when the software does not properly sanitize a specially crafted web request. This could allow a remote attacker to perform cross-site scripting attacks, potentially enabling them to read unauthorized content, use the victim's identity to take actions on the site, and inject malicious content into the user's browser.

Recommendations For Microsoft SharePoint Server, update the software to a version that properly sanitizes web requests to prevent cross-site scripting attacks. For Microsoft SharePoint Enterprise Server, apply configuration changes to ensure that web requests are properly sanitized, mitigating the risk of cross-site scripting attacks. As a temporary workaround, consider restricting access to sensitive areas of the SharePoint site to minimize the risk of exploitation.
