Vulnerability Mapping Notes

Justification : This CWE entry is extremely high-level, a Pillar. However, classification research is limited for weaknesses of this type, so there can be gaps or organizational difficulties within CWE that force use of this weakness, even at such a high level of abstraction.
Comment : Where feasible, consider children or descendants of this entry instead.

Related Attack Patterns

CAPEC-ID	Attack Pattern Name
CAPEC-29	Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
