Detailsinfo

A vulnerability was found in Microsoft .NET Framework 2.0 SP2/3.5/3.5.1/4/4.5 (Programming Language Software). It has been classified as critical. This affects some unknown processing of the component Permission Handler. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not properly check the permissions of objects that use reflection, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (XBAP) or (2) a crafted .NET Framework application, aka "Anonymous Method Injection Vulnerability."

The weakness was presented 07/09/2013 by James Forshaw with Context Information Security as MS13-052 as confirmed bulletin (Microsoft Technet). The advisory is shared at technet.microsoft.com. The public release was coordinated in cooperation with Microsoft. This vulnerability is uniquely identified as CVE-2013-3133 since 04/17/2013. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 67209 (MS13-052: Vulnerabilities in .NET Framework and Silverlight Could Allow Remote Code Execution (2861561)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90896 (Microsoft .NET Framework and Silverlight Multiple Code Execution Vulnerabilities (MS13-052)).

Applying the patch MS13-052 is able to eliminate this problem. The bugfix is ready for download at technet.microsoft.com. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (67209), OSVDB (94955†), Secunia (SA54025†) and Vulnerability Center (SBV-40400†). See VDB-9392, VDB-9394, VDB-9395 and VDB-9396 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
