| Vector | AV: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 crafted request, allowing them to perform cross-site scripting attacks, run scripts in the current user's security context, read unauthorized content, use the victim's identity to change permissions and delete content, and inject malicious content into the user's browser.
Recommendations
For Microsoft SharePoint Server, consider restricting access to sensitive areas of the server until a proper fix is applied.
For Microsoft SharePoint Foundation, as a temporary workaround, consider disabling any functionality that allows the execution of user-supplied input.
For Microsoft SharePoint Enterprise Server, restrict the ability to inject malicious content into user browsers by limiting the execution of scripts from untrusted sources.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
