CWE-1464
Weakness AllowedImproper Session Invalidation
Abstraction: Base · Status: Incomplete
The product establishes a session for an authenticated user, but it does not properly invalidate or terminate the session when it is required.
Mapping guidance
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.
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.
Modes of introduction
Detection methods
Dynamic Analysis with Manual Results Interpretation
Ensure that application testing includes scenarios that are intended to lead to session invalidation and verify that the session can no longer be used.

0 vulnerabilities reference this CWE, most recent first.
No vulnerabilities reference this CWE.
Mitigation
Ensure that user sessions are invalidated on the server-side for all possible security related events relevant to the application. It is important that the server-side handles all session invalidation and does not rely on the client to remove or delete a session, due to the possibility of adversaries capturing session identifiers or cookies for later reuse.
