Summary

The XSS Filter in Microsoft Internet Explorer 9 through 11 and Microsoft Edge does not properly restrict JavaScript code, which allows remote attackers to obtain sensitive information via a crafted web site, aka "Microsoft Browser Information Disclosure Vulnerability."

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • 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.

    descriptionThe version of Internet Explorer installed on the remote host is missing Cumulative Security Update 3169991. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these issues by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.

  • NASL familyWindows : Microsoft Bulletins
    NASL idSMB_NT_MS16-085.NASL
    descriptionThe version of Microsoft Edge installed on the remote Windows host is missing Cumulative Security Update 3169999. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists due to a failure to properly implement Address Space Layout Randomization (ASLR). An unauthenticated, remote attacker can exploit this, by convincing a user to visit a website that hosts crafted content, to bypass the ASLR security feature, resulting in the ability to predict memory offsets in a call stack. (CVE-2016-3244) - Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, via a crafted website or email, to corrupt memory, resulting in the execution of arbitrary code within the context of the current user. (CVE-2016-3246, CVE-2016-3264) - Multiple remote code execution vulnerabilities exist in the Chakra JavaScript engine due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website or open a specially crafted Microsoft Office document that hosts the Edge rendering engine, to corrupt memory, resulting in the execution of arbitrary code within the context of the current user. (CVE-2016-3248, CVE-2016-3259, CVE-2016-3260, CVE-2016-3265, CVE-2016-3269) - An information disclosure vulnerability exists in VBScript due to improper disclosure of the contents of its memory. An unauthenticated, remote attacker who has knowledge of the memory address where an object was created can exploit this issue to disclose potentially sensitive information. (CVE-2016-3271) - An information disclosure vulnerability exists in the Microsoft Browser XSS Filter due to improper validation of content. An unauthenticated, remote attacker can exploit this, via a website that hosts content with specially crafted JavaScript, to disclose potentially sensitive information. (CVE-2016-3273) - Multiple spoofing vulnerabilities exist due to improper parsing of HTTP or HTML content. An unauthenticated, remote attacker can exploit these to redirect a user to a malicious website having spoofed contents. (CVE-2016-3274, CVE-2016-3276) - An unspecified information disclosure vulnerability exists due to improper handling of objects in memory that allows an unauthenticated, remote attacker to disclose potentially sensitive information. (CVE-2016-3277)
