HTTP: Microsoft Sharepoint User XSS

This signature detects attempts to exploit a known cross site scripting vulnerability in Microsoft Sharepoint. A remote attacker can exploit this by enticing a target user to open a Sharepoint site. In a successful code injection attack, the behavior of the target host is entirely dependent on the intended function of the injected code and executes within the security context of the currently logged in user. If the attack is unsuccessful, the vulnerable application can terminate abnormally.

Extended Description

Microsoft SharePoint is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input. Attacker-supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
