Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

descriptionThe version of Microsoft Edge installed on the remote Windows host is missing Cumulative Security Update 3163656. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists due to a failure to properly validate specially crafted documents. An unauthenticated, remote attacker can exploit this vulnerability by convincing a user to load a page or visit a website containing malicious content, allowing the attacker to bypass the Edge Content Security Policy (CSP). (CVE-2016-3198) - 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 vulnerabilities by convincing a user to visit a specially crafted website or open a specially crafted Microsoft Office document that hosts the Edge rendering engine, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-3199, CVE-2016-3202, CVE-2016-3214, CVE-2016-3222) - Multiple information disclosure vulnerabilities exist due to improper parsing of .pdf files. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted .pdf file, resulting in the disclosure of sensitive information in the context of the current user. (CVE-2016-3201, CVE-2016-3215) - A remote code execution vulnerability exists due to improper parsing of .pdf files. An unauthenticated, remote attacker can exploit this vulnerability by convincing a user to open a specially crafted .pdf file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-3203) Note that CVE-2016-3214, CVE-2016-3215, and CVE-2016-3222 only affect Windows 10 version 1511.
