Detailsinfo

A vulnerability was found in Microsoft .NET Framework up to 4.5 (Programming Language Software). It has been rated as problematic. This issue affects an unknown functionality of the component Object Delegation. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, and integrity. The summary by CVE is:

The serialization functionality in Microsoft .NET Framework 2.0 SP2, 3.5, 3.5 SP1, 3.5.1, 4, and 4.5 does not properly check the permissions of delegate objects, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (XBAP) or (2) a crafted .NET Framework application that leverages a partial-trust relationship, aka "Delegate Serialization Vulnerability."

The weakness was published 07/09/2013 by James Forshaw with Context Information Security as MS13-052 as confirmed knowledge base article (Website). It is possible to read the advisory at support.microsoft.com. The public release has been coordinated with Microsoft. The identification of this vulnerability is CVE-2013-3171 since 04/17/2013. The attack can only be done within the local network. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1059 according to MITRE ATT&CK.
