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.

  - An arbitrary code execution vulnerability exists in
    Microsoft Outlook due to improper parsing of email
    messages. An unauthenticated, remote attacker can
    exploit this, via a specially crafted email message, to
    execute arbitrary code. (CVE-2017-0106)

  - An information disclosure vulnerability exists in
    Microsoft Office due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    this, by convincing a user to open a specially crafted
    Excel file, to disclose the contents of memory.
    (CVE-2017-0194)

  - A cross-site scripting (XSS) vulnerability exists in
    Office Web Apps Server due to improper validation of
    input before returning it to users. An authenticated,
    remote attacker can exploit this, via a specially
    crafted request, to execute arbitrary script code in a
    user's browser session. (CVE-2017-0195)

  - An arbitrary code execution vulnerability exists in
    Microsoft Office due to improper validation of input
    before loading dynamic link library (DLL) files. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to open a specially crafted Office
    document, to execute arbitrary code. (CVE-2017-0197)

  - An arbitrary code execution vulnerability exists in
    Microsoft Office and Windows WordPad due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit this, by convincing a user
    to open a specially crafted file, to execute arbitrary
    code. Note that this vulnerability is being utilized to
    spread the Petya ransomware. (CVE-2017-0199)

  - A security feature bypass vulnerability exists in
    Microsoft Office due to improper parsing of file
    formats. An unauthenticated, remote attacker can exploit
    this, by convincing a user into opening a specially
    crafted file, to bypass security features.
    (CVE-2017-0204)

  - A spoofing vulnerability in Microsoft Outlook due to
    improper validation of input passed via HTML tags. An
    unauthenticated, remote attacker can exploit this, by
    sending an email with specific HTML tags, to display a
    malicious authentication prompt and gain access to a

    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)
