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.

| description | The remote Windows host is missing security update 4048955. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-11827, CVE-2017-11858) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-11837, CVE-2017-11838, CVE-2017-11843, CVE-2017-11846) - An information disclosure vulnerability exists when Microsoft Edge improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11803, CVE-2017-11844) - A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-11855, CVE-2017-11856, CVE-2017-11869) - An information vulnerability exists when Windows Media Player improperly discloses file information. Successful exploitation of the vulnerability could allow the attacker to test for the presence of files on disk. (CVE-2017-11768) - An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory in Internet Explorer. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11834) - A security feature bypass vulnerability exists in Microsoft Edge when the Edge Content Security Policy (CSP) fails to properly validate certain specially crafted documents. An attacker who exploited the bypass could trick a user into loading a page containing malicious content. (CVE-2017-11863) - An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory. (CVE-2017-11880) - A Win32k information disclosure vulnerability exists when the Windows GDI component improperly discloses kernel memory addresses. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11851) - A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Microsoft Edge. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-11836, CVE-2017-11839, CVE-2017-11840, CVE-2017-11841, CVE-2017-11861, CVE-2017-11862, CVE-2017-11866, CVE-2017-11870, CVE-2017-11871, CVE-2017-11873) - An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory in Microsoft browsers. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11791) - A security feature bypass vulnerability exists in Microsoft Edge as a result of how memory is accessed in code compiled by the Edge Just-In-Time (JIT) compiler that allows Control Flow Guard (CFG) to be bypassed. By itself, this CFG bypass vulnerability does not allow arbitrary code execution. However, an attacker could use the CFG bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system. (CVE-2017-11874) - A security feature bypass exists when Device Guard incorrectly validates an untrusted file. An attacker who successfully exploited this vulnerability could make an unsigned file appear to be signed. Because Device Guard relies on the signature to determine the file is non- malicious, Device Guard could then allow a malicious file to execute. In an attack scenario, an attacker could make an untrusted file appear to be a trusted file. The update addresses the vulnerability by correcting how Device Guard handles untrusted files. (CVE-2017-11830) - An information disclosure vulnerability exists when Internet Explorer improperly handles page content, which could allow an attacker to detect the navigation of the user leaving a maliciously crafted page. (CVE-2017-11848) - An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2017-11831, CVE-2017-11842, CVE-2017-11849, CVE-2017-11853) - An information disclosure vulnerability exists when the Microsoft Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11850) - An information disclosure vulnerability exists in the way that Microsoft Edge handles cross-origin requests. An attacker who successfully exploited this vulnerability could determine the origin of all webpages in the affected browser. (CVE-2017-11833) |
