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_JUL_INTERNET_EXPLORER.NASL description The Internet Explorer installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists when Microsoft browsers improperly handle redirect requests. The vulnerability allows Microsoft browsers to bypass CORS redirect restrictions, and to follow redirect requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted to a destination website of the attacker last seen 2020-06-01 modified 2020-06-02 plugin id 104891 published 2017-11-30 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/104891 title Security Updates for Internet Explorer (July 2017) NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS17_JUL_4025336.NASL description The remote Windows host is missing security update 4025333 or cumulative update 4025336. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists in the Windows Performance Monitor Console due to improper parsing of XML input that contains a reference to an external entity. An unauthenticated, remote attacker can exploit this, by convincing a user to create a Data Collector Set and import a specially crafted XML file, to disclose arbitrary files via an XML external entity (XXE) declaration. (CVE-2017-0170) - A remote code execution vulnerability exists in Windows Explorer due to improper handling of executable files and shares during rename operations. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code in the context of the current user. (CVE-2017-8463) - An elevation of privilege vulnerability exists in the Microsoft Graphics component due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to run arbitrary code in kernel mode. (CVE-2017-8467) - An information disclosure vulnerability exists in Win32k due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to disclose sensitive information. (CVE-2017-8486) - A security bypass vulnerability exists in Microsoft Windows when handling Kerberos ticket exchanges due to a failure to prevent tampering with the SNAME field. A man-in-the-middle attacker can exploit this to bypass the Extended Protection for Authentication security feature. (CVE-2017-8495) - An elevation of privilege vulnerability exists in the Microsoft Graphics component due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to run arbitrary code in kernel mode. (CVE-2017-8556) - An information disclosure vulnerability exists in the Windows System Information Console due to improper parsing of XML input that contains a reference to an external entity. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to disclose arbitrary files via an XML external entity (XXE) declaration. (CVE-2017-8557) - An elevation of privilege vulnerability exists in the Windows kernel due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to execute arbitrary code with elevated permissions. (CVE-2017-8561) - An elevation of privilege vulnerability exists in Windows due to improper handling of calls to Advanced Local Procedure Call (ALPC). An authenticated, remote attacker can exploit this via a specially crafted application, to run processes in an elevated context. (CVE-2017-8562) - An elevation of privilege vulnerability exists in Windows due to Kerberos falling back to NT LAN Manager (NTLM) Authentication Protocol as the default authentication protocol. An authenticated, remote attacker can exploit this, via an application that sends specially crafted traffic to a domain controller, to run processes in an elevated context. (CVE-2017-8563) - An information disclosure vulnerability exists in the Windows kernel due to improper initialization of objects in memory. An authenticated, remote attacker can exploit this, via a specially crafted application, to bypass Kernel Address Space Layout Randomization (KASLR) and disclose the base address of the kernel driver.
