ID CVE-2017-0057
Summary DNS client in Microsoft Windows 8.1; Windows Server 2012 R2, Windows RT 8.1; Windows 10 Gold, 1511, and 1607; and Windows Server 2016 fails to properly process DNS queries, which allows remote attackers to obtain sensitive information via (1) convincing a workstation user to visit an untrusted webpage or (2) tricking a server into sending a DNS query to a malicious DNS server, aka "Windows DNS Query Information Disclosure Vulnerability."
Vulnerable Configurations

  • cpe:2.3:o:microsoft:windows_10
  • cpe:2.3:o:microsoft:windows_10:1511
  • cpe:2.3:o:microsoft:windows_10:1607
  • Microsoft Windows RT 8.1
  • cpe:2.3:o:microsoft:windows_server_2012:r2
  • cpe:2.3:o:microsoft:windows_8.1
Base: 4.3 (as of 20-03-2017 - 13:46)
  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

NASL family Windows : Microsoft Bulletins
description The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists in Device Guard due to improper validation of certain elements in a signed PowerShell script. An unauthenticated, remote attacker can exploit this vulnerability to modify the contents of a PowerShell script without invalidating the signature associated with the file, allowing the execution of a malicious script. (CVE-2017-0007) - A denial of service vulnerability exists in the Microsoft Server Message Block 2.0 and 3.0 (SMBv2/SMBv3) client implementations due to improper handling of certain requests sent to the client. An unauthenticated, remote attacker can exploit this issue, via a malicious SMB server, to cause the system to stop responding until it is manually restarted. (CVE-2017-0016) - A remote code execution vulnerability exists due to using an insecure path to load certain dynamic link library (DLL) files. A local attacker can exploit this, via a specially crafted library placed in the path, to execute arbitrary code. (CVE-2017-0039) - An information disclosure vulnerability exists in Windows dnsclient due to improper handling of certain requests. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted web page, to gain access to sensitive information on a targeted workstation. If the target is a server, the attacker can also exploit this issue by tricking the server into sending a DNS query to a malicious DNS server. (CVE-2017-0057) - An elevation of privilege vulnerability exists in Helppane.exe due to a failure by an unspecified DCOM object, configured to run as the interactive user, to properly authenticate the client. An authenticated, remote attacker can exploit this, via a specially crafted application, to execute arbitrary code in another user's session. (CVE-2017-0100) - An integer overflow condition exists in the iSNS Server service due to improper validation of input from the client. An unauthenticated, remote attacker can exploit this issue, via a specially crafted application that connects and issues requests to the iSNS server, to execute arbitrary code in the context of the SYSTEM account. (CVE-2017-0104)
