Detailsinfo

A vulnerability classified as critical was found in Microsoft .NET Framework 2.0 SP2/3.5/3.5.1/4/4.5 (Programming Language Software). Affected by this vulnerability is an unknown part of the component Array Handler. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, and integrity. The summary by CVE is:

Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5, and Silverlight 5 before 5.1.20513.0, does not properly prevent changes to data in multidimensional arrays of structures, which allows remote attackers to execute arbitrary code via (1) a crafted .NET Framework application or (2) a crafted Silverlight application, aka "Array Access Violation Vulnerability."

The weakness was disclosed 07/09/2013 by Alon Fliess as MS13-052 as confirmed knowledge base article (Website). The advisory is shared at support.microsoft.com. The public release happened without involvement of Microsoft. This vulnerability is known as CVE-2013-3131 since 04/17/2013. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059 for this issue.
