Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • 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.
  • XML Nested Payloads
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. By nesting XML data and causing this data to be continuously self-referential, an attacker can cause the XML parser to consume more resources while processing, causing excessive memory consumption and CPU utilization. An attacker's goal is to leverage parser failure to his or her advantage. In most cases this type of an attack will result in a denial of service due to an application becoming unstable, freezing, or crash. However it may be possible to cause a crash resulting in arbitrary code execution, leading to a jump from the data plane to the control plane [R.230.1].
  • XML Oversized Payloads
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. By supplying oversized payloads in input vectors that will be processed by the XML parser, an attacker can cause the XML parser to consume more resources while processing, causing excessive memory consumption and CPU utilization, and potentially cause execution of arbitrary code. An attacker's goal is to leverage parser failure to his or her advantage. In many cases this type of an attack will result in a denial of service due to an application becoming unstable, freezing, or crash. However it is possible to cause a crash resulting in arbitrary code execution, leading to a jump from the data plane to the control plane [R.231.1].
  • XML Client-Side Attack
    Client applications such as web browsers that process HTML data often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. These adverse effects may include the parser crashing, consuming too much of a resource, executing too slowly, executing code supplied by an attacker, allowing usage of unintended system functionality, etc. An attacker's goal is to leverage parser failure to his or her advantage. In some cases it may be possible to jump from the data plane to the control plane via bad data being passed to an XML parser. [R.484.1]
  • XML Parser Attack
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. These adverse effects may include the parser crashing, consuming too much of a resource, executing too slowly, executing code supplied by an attacker, allowing usage of unintended system functionality, etc. An attacker's goal is to leverage parser failure to his or her advantage. In some cases it may be possible to jump from the data plane to the control plane via bad data being passed to an XML parser. [R.99.1]

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)
