CAPEC-124: Shared Resource Manipulation

Attack Pattern ID: 124
Abstraction: Meta
View customized information:
+ Description
An adversary exploits a resource shared between multiple applications, an application pool or hardware pin multiplexing to affect behavior. Resources may be shared between multiple applications or between multiple threads of a single application. Resource sharing is usually accomplished through mutual access to a single memory location or multiplexed hardware pins. If an adversary can manipulate this shared resource (usually by co-opting one of the applications or threads) the other applications or threads using the shared resource will often continue to trust the validity of the compromised shared resource and use it in their calculations. This can result in invalid trust assumptions, corruption of additional data through the normal operations of the other users of the shared resource, or even cause a crash or compromise of the sharing applications.

Section HelpThis table shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf and ParentOf, and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.
PeerOfStandard Attack PatternStandard Attack Pattern - A standard level attack pattern in CAPEC is focused on a specific methodology or technique used in an attack. It is often seen as a singular piece of a fully executed attack. A standard attack pattern is meant to provide sufficient details to understand the specific technique and how it attempts to accomplish a desired goal. A standard level attack pattern is a specific type of a more abstract meta level attack pattern.663Exploitation of Transient Instruction Execution
Section HelpThis table shows the views that this attack pattern belongs to and top level categories within that view.
+ Prerequisites
The target applications, threads or functions must share resources between themselves.
The adversary must be able to manipulate some piece of the shared resource either directly or indirectly and the other users of the data must accept the changed data as valid. Usually this requires that the adversary be able to compromise one of the sharing applications or threads in order to manipulate the shared data.
+ Resources Required
None: The attacker does not need any specialized resources to execute this type of attack.
