Name of the Vulnerable Software and Affected Versions Microsoft SharePoint 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 a remote attacker to perform cross-site scripting attacks by sending a specially crafted request to an affected SharePoint server. The attacker could then run script in the security context of the current user, potentially allowing them to read unauthorized content, use the victim's identity to take actions on the SharePoint site, and inject malicious content in the user's browser.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
