Microsoft SharePoint CVE-2013-0085 Denial of Service Vulnerability

Description

Microsoft SharePoint is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause the application to become unresponsive, denying service to legitimate users.

Technologies Affected

• Microsoft SharePoint Foundation 2010 SP1
• Microsoft SharePoint Server 2010 SP1

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn’t needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.

Updates are available. Please see the references or vendor advisory for more information.
