UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
Microsoft .NET Framework 2.0 SP2, 3.5.1, and 4, and Silverlight 4 before 4.1.10111, does not properly restrict access to memory associated with unmanaged objects, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, (3) a crafted .NET Framework application, or (4) a crafted Silverlight application, aka ".NET Framework Unmanaged Objects Vulnerability."
Vulnerable Configurations
Common Weakness Enumeration (CWE)
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.

NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS12-016.NASL description The version of the .NET Framework installed on the remote host reportedly is affected by the following vulnerabilities : - The .NET Framework and Silverlight do not properly use unmanaged objects, which could allow a malicious .NET Framework application to access memory in an unsafe manner. (CVE-2012-0014) - The .NET Framework does not properly calculate a buffer length when processing malicious input, which could lead to heap corruption. (CVE-2012-0015) An attacker may be able to leverage these vulnerabilities to execute arbitrary code on the affected system if a user on it can be tricked into viewing a specially crafted web page using a web browser that can run XAML Browser Applications (XBAPs) or Silverlight applications. last seen 2020-06-01 modified 2020-06-02 plugin id 57950 published 2012-02-14 reporter This script is Copyright (C) 2012-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/57950 title MS12-016: Vulnerabilities in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2651026) code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(57950); script_version("1.18"); script_cvs_date("Date: 2018/11/15 20:50:31"); script_cve_id("CVE-2012-0014", "CVE-2012-0015"); script_bugtraq_id(51938, 51940); script_xref(name:"MSFT", value:"MS12-016"); script_xref(name:"MSKB", value: "2668562"); script_xref(name:"MSKB", value: "2633869"); script_xref(name:"MSKB", value: "2638804"); script_xref(name:"MSKB", value: "2633870"); script_xref(name:"MSKB", value: "2633873"); script_xref(name:"MSKB", value: "2633879"); script_xref(name:"MSKB", value: "2633877"); script_xref(name:"MSKB", value: "2633874"); script_xref(name:"MSKB", value: "2633880"); script_name(english:"MS12-016: Vulnerabilities in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2651026)"); script_summary(english:"Checks version of Silverlight.exe / system.dll"); script_set_attribute( attribute:"synopsis", value: "The .NET Framework install on the remote Windows host could allow arbitrary code execution." ); script_set_attribute( attribute:"description", value: "The version of the .NET Framework installed on the remote host reportedly is affected by the following vulnerabilities : - The .NET Framework and Silverlight do not properly use unmanaged objects, which could allow a malicious .NET Framework application to access memory in an unsafe manner.
