VectorAV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
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 improper sanitization of specially crafted web requests. An authenticated attacker could exploit this by sending a specially crafted request, allowing them to perform cross-site scripting attacks, read unauthorized content, use the victim's identity to take actions on the SharePoint site, and inject malicious content into the user's browser.
Recommendations For Microsoft SharePoint Server, consider restricting access to sensitive areas of the site until a fix is available. For Microsoft SharePoint Foundation, restrict the ability to send specially crafted requests to affected servers as a temporary mitigation measure. For Microsoft SharePoint Enterprise Server, as a workaround, limit the permissions of users who could potentially exploit the vulnerability. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
