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 remote Windows host is affected by multiple vulnerabilities : - Multiple remote code execution vulnerabilities exist due to the Windows Adobe Type Manager Library not properly handling specially crafted OpenType fonts. An attacker can exploit these, by using a crafted document or web page with embedded OpenType fonts, to execute arbitrary code in the context of the current user. (CVE-2015-2432, CVE-2015-2458, CVE-2015-2459, CVE-2015-2460, CVE-2015-2461, CVE-2015-2462) - Multiple remote code execution vulnerabilities exist in various components of Windows, .NET Framework, Office, Lync, and Silverlight due to a failure to properly handle TrueType fonts. An attacker can exploit these, by using a crafted document or web page with embedded TrueType fonts, to execute arbitrary code in the context of the current user. (CVE-2015-2435, CVE-2015-2455, CVE-2015-2456 CVE-2015-2463, CVE-2015-2464) - A remote code execution vulnerability exists due to Microsoft Office not properly handling Office Graphics Library (OGL) fonts. An attacker can exploit this, by using a crafted document or web page with embedded OGL fonts, to execute arbitrary code in the context of the user. (CVE-2015-2431) - A security feature bypass vulnerability exists due to a failure by the Windows kernel to properly initialize a memory address. An attacker, using a specially crafted application, can exploit this issue to bypass Kernel Address Space Layout Randomization (KASLR) and retrieve the base address of the kernel driver. (CVE-2015-2433) - An elevation of privilege vulnerability exists due to a flaw in the Windows Client/Server Run-time Subsystem (CSRSS) when terminating a process when a user logs off. An attacker can exploit this vulnerability to run code that monitors the actions of users who log on to the system, allowing the disclosure of sensitive information which could be used to elevate privileges or execute code. (CVE-2015-2453) - A security feature bypass vulnerability exists due to the Windows kernel-mode driver not properly validating and enforcing impersonation levels. An attacker can exploit this to gain elevated privileges on a targeted system. (CVE-2015-2454) - A security feature bypass vulnerability exists due to the Windows shell not properly validating and enforcing impersonation levels. An attacker can exploit this to bypass impersonation-level security and gain elevated privileges on a targeted system. (CVE-2015-2465)
