Mögliche Gegenmaßnahmen
Phases : Architecture and DesignAdopting design practices that encourage designers to recognize and eliminate race conditions, such as Karnaugh maps, could result in the decrease in occurrences of race conditions.
Phases : Implementation
Logic redundancy can be implemented along security critical paths to prevent race conditions. To avoid metastability, it is a good practice in general to default to a secure state in which access is not given to untrusted agents.
Hinweise zur Schwachstellen-Zuordnung
Begründung : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Kommentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

| CAPEC-26 | Leveraging Race Conditions
The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file. |
