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 Microsoft Office application or Microsoft Office Services and Web Apps installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - An arbitrary command execution vulnerability exists in Microsoft Office due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted Office file, resulting in a bypass of security restrictions and the execution of arbitrary commands. (CVE-2016-7262) - Multiple remote code execution vulnerabilities exist in Microsoft Office software due to a failure to properly handle objects in memory. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-7263, CVE-2016-7277, CVE-2016-7289, CVE-2016-7298) - Multiple information disclosure vulnerabilities exist in Microsoft Office software due to an out-of-bounds memory read error. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted Office file, resulting in the disclosure of memory contents. (CVE-2016-7264, CVE-2016-7265, CVE-2016-7268, CVE-2016-7276, CVE-2016-7290, CVE-2016-7291) - An arbitrary command execution vulnerability exists in Microsoft Office due to improper validation of registry settings when running embedded content. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted document file multiple times, resulting in a bypass of security restrictions and the execution of arbitrary commands. (CVE-2016-7266) - A security bypass vulnerability exists in Microsoft Office due to improper parsing of file formats. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted Office file, resulting in a bypass security restrictions. (CVE-2016-7267) - An elevation of privilege vulnerability exists in Microsoft Office due to improper validation before loading libraries. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2016-7275)
