Web Services on Devices API Memory Corruption Vulnerability - CVE-2009-2512 --------------------------------------------------------------------------- A remote code execution vulnerability exists in the Web Services on Devices API (WSDAPI) on Windows systems. The vulnerability is due to the service not properly handling a WSDAPI message with a specially crafted header. An attacker who successfully exploited this vulnerability could take complete control of an affected system. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see [CVE-2009-2512](http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2009-2512). #### Mitigating Factors for Web Services on Devices API Memory Corruption Vulnerability - CVE-2009-2512 Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation: - Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed. - Only attackers on the local subnet would be able to exploit this vulnerability without interaction. Even on private networks, the vulnerable service is only exposed to incoming connections from the local subnet in the Windows firewall. #### Workarounds for Web Services on Devices API Memory Corruption Vulnerability - CVE-2009-2512 Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality: - **Block inbound TCP ports 5357 and 5358, and outbound UDP port 3702** Configure the Windows Firewall to block inbound TCP ports 5357 and 5358, and outbound UDP port 3702. Blocking the inbound ports prevents malicious remote hosts from sending specially crafted headers to the affected component. The affected computer may also initiate a connection with remote, potentially malicious, hosts when the user chooses to browse devices on the subnet. Blocking the outbound port will prevent malicious hosts from sending specially crafted replies in this scenario. It should be noted that it will still be possible for a user to manually enter the URL of a malicious device and initiate a connection that could allow the malicious device to compromise the user's system. This attack would require significant social engineering. **Impact of workaround.** Device discovery will not work while this workaround is enabled. #### FAQ for Web Services on Devices API Memory Corruption Vulnerability - CVE-2009-2512 **What is the scope of the vulnerability?**  This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. If successfully exploited, an attacker could then install programs or view, change, or delete data; or create new accounts with full user rights. **What causes the vulnerability?**  This vulnerability is caused by the WSD Application Programming Interface (API), on both clients and servers, not correctly validating specific headers of a received WSD message. **What is Microsoft Web Services on Devices?**  Web Services on Devices allows a Windows client to discover and access remote devices, such as personal digital assistants (PDAs) and computer peripherals, including printers and cameras, as well as consumer electronics and their associated services across a network. It supports device discovery, description, and control. Developers can create WSDAPI client proxies and corresponding stubs for device hosts. Web Services on Devices API (WSDAPI) implements the Devices Profile for Web Services (DPWS) for Windows Vista and Windows Server 2008. The DPWS constrains Web Services specifications so that Windows clients can easily discover devices. Once a device is discovered, a client can retrieve a description of services hosted on that device and use those services. **Is Web Services for Devices enabled by default?**  Web Services for Devices is an Application Programming Interface (API) that can be used by various system components. On all affected platforms, the API is available by default. However, the vulnerability can only be exploited remotely and without user interaction when a service or application uses the API and exposes TCP port 5357 or 5358 or performs remote device discovery. This is likely to be the case in common scenarios that involve connecting supported devices such as printers and video devices to the network. **What might an attacker use the vulnerability to do?**  An attacker who successfully exploited this vulnerability could take complete control of the affected Windows system. An attacker could then install programs or view, change, or delete data; or create new accounts with full user rights. **How could an attacker exploit the vulnerability?**  An attacker could try to exploit the vulnerability by sending a specially crafted message to the WSD TCP ports 5357 or 5358 on an affected system. Alternatively, an attacker could send a specially crafted response to a WSD message querying for devices, when initiated by the Windows client. Note that applications that use the WSDAPI may use ports other than TCP ports 5357 and 5358, which are the defaults. **What systems are primarily at risk from the vulnerability?**  All systems using WSDAPI for communicating with DPWS-based devices or services on the network are affected by this vulnerability. Workstations are at particular risk when they have their Windows firewall configuration set to anything else but "public". **What does the update do?**  The update addresses this vulnerability by correctly processing WSD message headers. **When this security bulletin was issued, had this vulnerability been publicly disclosed?**  No. Microsoft received information about this vulnerability through responsible disclosure. **When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?**  No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued. ### Update Information Detection and Deployment Tools and Guidance ------------------------------------------- Manage the software and security updates you need to deploy to the servers, desktop, and mobile systems in your organization.
