CVSS SCORES: Base 9.3/ Temporal 7.3
THREAT: Microsoft Internet Explorer is a Web browser available for Microsoft Windows.

Microsoft IE is prone to the following vulnerabilities:

- An information disclosure vulnerability exists that potentially allows form data within Internet Explorer to be captured via the AutoComplete feature. (CVE-2010-0808)

- An information disclosure vulnerability exists in the way that the toStaticHTML API sanitizes HTML and this could allow an attacker to perform cross-site scripting attacks and run script in the security context of the logged-on user. (CVE-2010-3243,CVE-2010-3324)

- An information disclosure vulnerability exists in the way that Internet Explorer processes CSS special characters. (CVE-2010-3325)

This behavior occurs during user operation when the Anchor element is not removed during content pasting and editing, potentially revealing personally identifiable information intended for deletion. (CVE-2010-3327)

- An information disclosure vulnerability exists in Internet Explorer that could allow script to gain access to information in another domain or Internet Explorer zone. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow information disclosure if a user viewed the Web page. (CVE-2010-3330)

Microsoft has released a security update that addresses these vulnerabilities by modifying the way that Internet Explorer handles objects in memory, CSS special characters, HTML sanitization, the AutoComplete feature, the Anchor element, and script during certain processes.

Refer to Microsoft Security Bulletin MS10-079 for further details.

Workarounds:
1) Avoid opening Office (Word) files received from untrusted sources.

2) Use the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or un-trusted sources because it protects Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files. Information on MOICE can be found at KB935865.

Impact of the workaround:
Office 2003 and earlier formatted documents that are converted to the 2007 Microsoft Office System Open XML format by MOICE lose their macro functionality. Documents protected with passwords and Digital Rights Management cannot be converted.

3) Microsoft Office File Block policy should be used to block the opening of Office 2003 and earlier documents from unknown or untrusted sources.

Impact of the workaround:
If File Block policy is configured without special "exempt directory" configuration (see KB922848), Office 2003 files or earlier versions will not open in Office 2003 or 2007 Microsoft Office System.

Refer to the advisory for obtaining additional details on applying the workarounds.

Microsoft Windows Shared Cluster Disks Tampering Vulnerability (MS10-086)
SEVERITY: Critical Critical-4 4
QUALYS ID: 90657
VENDOR REFERENCE: MS10-086
CVE REFERENCE: CVE-2010-3223
CVSS SCORES: Base 10/ Temporal 7.4
THREAT: A tampering vulnerability exists in the way the Failover Cluster Manager user interface handles permissions on shared cluster disks.

This vulnerability exists because the Failover Cluster Manager uses unsecured default permissions when adding disks to a cluster. When an administrator adds a disk to a shared cluster, the Failover Cluster Manager sets permissions on the shared cluster disk in a way that potentially provides unauthorized users (everyone) with read/write/delete access to the administrative shares on the failover cluster disk. (CVE-2010-3223)

Microsoft has released a security update that addresses this vulnerability by changing the way the Microsoft Cluster Service user interface sets permissions on administrative shares when adding or creating new shared cluster disks.

This security update is rated Moderate for all supported editions of Windows Server 2008 R2.

IMPACT: An attacker who successfully exploited this vulnerability could arbitrarily add, change, delete, or read data on an affected file system.
SOLUTION: Patch:
Following are links for downloading patches to fix the vulnerabilities:

Windows Server 2008 R2 for x64-based Systems

Windows Server 2008 R2 for Itanium-based Systems

Refer to Microsoft Security Bulletin MS10-086 for further details.

Workarounds:
After creating a cluster disk administrative share, manually configure its Access Control List to reflect the access permissions appropriate for the environment. Refer to the advisory to obtain additional information on applying the workarounds.
