PLATFORM: Windows XP (all editions) Windows Server 2003 (all editions) DAMAGE: Remote code execution. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is LOW. An attacker could exploit the vulnerability by ASSESSMENT: passing malicious input to a Web site’s ASP page. An attacker who successfully exploited this vulnerability could then perform any actions on the IIS Server with the same rights as the Worker Process Identity (WPI), which by default is configured with Network Service account privileges. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/s-183.shtml ORIGINAL BULLETIN: http://www.microsoft.com/technet/security/Bulletin/MS08-006.mspx CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2008-0075 ______________________________________________________________________________ REVISION HISTORY: 02/21/2008 - revised S=183 to reflect changes Microsoft has made in MS08-006 where they updated filenames changed in the file information table for all supported 32-bit editions of Windows XP. [***** Start Microsoft Security Bulletin (MS08-006) *****] Microsoft Security Bulletin MS08-006 – Important Vulnerability in Internet Information Services Could Allow Remote Code Execution (942830) Published: February 12, 2008 | Updated: February 20, 2008 Version: 1.1 General Information Executive Summary This important update resolves a privately reported vulnerability in Internet Information Services (IIS). A remote code execution vulnerability exists in the way that IIS handles input to ASP Web pages. An attacker who successfully exploited this vulnerability could then perform actions on the IIS server with the same rights as the Worker Process Identity (WPI). The WPI is configured with Network Service account privileges by default. IIS servers with ASP pages whose application pools are configured with a WPI that uses an account with administrative privileges could be more seriously impacted than IIS servers whose application pool is configured with the default WPI settings. The security update is rated important for Microsoft Internet Information Services on all supported editions of Windows XP and Windows Server 2003. For more information, see the subsection, Affected and Non-Affected Software, in this section. For more information about these vulnerabilities, see the Frequently Asked Questions (FAQ) subsection under the next section, Vulnerability Information. Recommendation. Microsoft recommends that customers apply the update at the earliest opportunity. Known Issues. None Top of section Affected and Non-Affected Software The following software have been tested to determine which versions or editions are affected. Other versions or editions are either past their support life cycle or are not affected. To determine the support life cycle for your software version or edition, visit Microsoft Support Lifecycle.

However, for the ASP Vulnerability (CVE-2008-0075), default configurations of Windows Small Business Server 2003 have a greater exposure to the same vulnerability and therefore merit a severity rating of Critical.

Update Information Detection and Deployment Tools and Guidance Manage the software and security updates you need to deploy to the servers, desktop, and mobile computers in your organization. For more information see the TechNet Update Management Center. The Microsoft TechNet Security Web site provides additional information about security in Microsoft products. Security updates are available from Microsoft Update, Windows Update, and Office Update. Security updates are also available from the Microsoft Download Center. You can find them most easily by doing a keyword search for "security update." Finally, security updates can be downloaded from the Microsoft Update Catalog. The Microsoft Update Catalog provides a searchable catalog of content made available through Windows Update and Microsoft Update, including security updates, drivers and service packs. By searching using the security bulletin number (such as, “MS07-036”), you can add all of the applicable updates to your basket (including different languages for an update), and download to the folder of your choosing. For more information about the Microsoft Update Catalog, see the Microsoft Update Catalog FAQ. Detection and Deployment Guidance Microsoft has provided detection and deployment guidance for this month’s security updates. This guidance will also help IT professionals understand how they can use various tools to help deploy the security update, such as Windows Update, Microsoft Update, Office Update, the Microsoft Baseline Security Analyzer (MBSA), the Office Detection Tool, Microsoft Systems Management Server (SMS), and the Extended Security Update Inventory Tool. For more information, see Microsoft Knowledge Base Article 910723.
