Common Weakness Enumeration (CWE)
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.

NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS17-007.NASL description The version of Microsoft Edge installed on the remote Windows host is missing Cumulative Security Update 4013071. It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. Note that in order to be fully protected from CVE-2017-0071, Microsoft recommends the July 2017 security updates to be installed. last seen 2020-06-01 modified 2020-06-02 plugin id 97730 published 2017-03-14 reporter This script is Copyright (C) 2017-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/97730 title MS17-007: Cumulative Security Update for Microsoft Edge (4013071) NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS17-009.NASL description The remote Windows host is missing a security update.
