Microsoft has released 1 security bulletins to fix newly discovered flaws in their software. Qualys has released the following checks for these new vulnerabilities:
SharePoint is prone to the following vulnerabilities:
- Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 do not properly validate input that is provided to an HTML query before sending this input to the browser.
- A vulnerability is caused by the way that the toStaticHTML API sanitizes HTML on a SharePoint site.
- A vulnerability exists due to the way that Microsoft SharePoint handles specially crafted requests sent to the Help page.
Microsoft has released a security update that addresses these vulnerabilities by modifying the way that Microsoft SharePoint validates input that is provided to an HTTP query, the way that toStaticHTML sanitizes HTML content in Microsoft SharePoint, and the way that Microsoft SharePoint handles specially crafted requests to the Help page.
This security update also addresses the vulnerability first described in Microsoft Security Advisory 983438.
Refer to Microsoft Security Bulletin MS10-039 for further details.
- Restrict Access to SharePoint Help.aspx
An administrator can apply an access control list to SharePoint Help.aspx to ensure that it can no longer be loaded. This effectively prevents exploitation of the vulnerability using this attack vector.
Impact of the workaround: This workaround will disable all help functionality from the SharePoint server.
- Set Internet and Local intranet security zone settings to "High" to prompt before running ActiveX Controls and Active Scripting.
Impact of the workaround: On visiting Web sites on the Internet or Intranet that use ActiveX or Active Scripting to provide additional functionality, you will be prompted frequently when you enable this workaround.
