UNKNOWN Summary
The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0, 2.0 SP1, 2.0 SP2, 3.5, and 3.5 SP1, and Silverlight 2, does not properly handle interfaces, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (XBAP), (2) a crafted Silverlight application, (3) a crafted ASP.NET application, or (4) a crafted .NET Framework application, aka "Microsoft Silverlight and Microsoft .NET Framework CLR Vulnerability."

Common Attack Pattern Enumeration and Classification (CAPEC)
- Leverage Executable Code in Non-Executable Files An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
- Manipulating User-Controlled Variables This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An attacker can override environment variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the attacker can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

description | The remote Windows host is running a version of the Microsoft .NET Framework that is affected by multiple vulnerabilities : - A remote code execution vulnerability exists in the Microsoft .NET Framework that could allow a malicious Microsoft .NET application to obtain a managed pointer to stack memory that is no longer used. The malicious Microsoft .NET application could then use this pointer to modify legitimate values placed at that stack location later, leading to arbitrary, unmanaged code execution. Microsoft .NET applications that are not malicious are not at risk for being compromised because of this vulnerability.(CVE-2009-0090) - A remote code execution vulnerability exists in the Microsoft .NET Framework that could allow a malicious Microsoft .NET application to bypass a type equality check. The malicious Microsoft .NET could exploit this vulnerability by casting an object of one type into another type, leading to arbitrary, unmanaged code execution. Microsoft .NET applications that are not malicious are not at risk for being compromised because of this vulnerability.(CVE-2009-0091) - A remote code execution vulnerability exists in the Microsoft .NET Framework that can allow a malicious Microsoft .NET application or a malicious Silverlight application to modify memory of the attacker |
