HTTP: Microsoft SharePoint Server Contact Details Reflected Cross Site Scripting
This signature detects attempts to exploit a known cross-site scripting vulnerability in Microsoft SharePoint Server. It is due to insufficient validation of user-supplied input. Attackers can steal cookie-based authentication credentials and launch other attacks.
Extended Description
Microsoft SharePoint is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to perform unauthorized actions on the SharePoint site on behalf of the user, redirect the user to malicious sites, or steal the user's credentials.
