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.

    descriptionThe version of Microsoft Outlook installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists in the way that Microsoft Outlook parses specially crafted email messages. An attacker who successfully exploited the vulnerability could take control of an affected system to then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2017-0106) - A security feature bypass vulnerability exists in Microsoft Office software when it improperly handles the parsing of file formats. To exploit the vulnerability, an attacker would have to convince a user to open a specially crafted file. (CVE-2017-0204) - A remote code execution vulnerability exists when Microsoft Office improperly validates input before loading dynamic link library (DLL) files. An attacker who successfully exploited this vulnerability could take control of an affected system to then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2017-8506) - A remote code execution vulnerability exists in the way that Microsoft Outlook parses specially crafted email messages. An attacker who successfully exploited this vulnerability could take control of an affected system. (CVE-2017-8507) - A security feature bypass vulnerability exists in Microsoft Office software when it improperly handles the parsing of file formats. (CVE-2017-8508) - A security feature bypass vulnerability exists when Microsoft Office Outlook improperly handles input. An attacker who successfully exploited the vulnerability could execute arbitrary commands. (CVE-2017-8571) - An information disclosure vulnerability exists when Microsoft Outlook fails to properly validate authentication requests. (CVE-2017-8572) - A remote code execution vulnerability exists in the way that Microsoft Outlook parses specially crafted email messages. An attacker who successfully exploited the vulnerability could take control of an affected system. (CVE-2017-8663)
