Description |
| Bad JWT expiration |
| JavaScript SDK does not set an expiration time for JWE tokens related to a session |
| Web interface for a power quality analyzer uses tokens without an expiration date |
| network traffic analyzer for PROFINET networks does not expire sessions |
| AI/ML monitor for IT operations allows re-use of old session tokens due to insufficient session expiration |
| No absolute session expiration |
Potential Mitigations
Phases : Implementation
Ensure that user sessions have appropriate absolute timeouts set. The industry standard is between 4 and 8 hours for an absolute timeout [REF-1540].
Phases : Implementation
Ensure that user sessions have appropriate inactivity timeouts set. 2 to 5 minutes is recommended for high-value applications, and 15-30 minutes for low-risk applications [REF-1540].
Phases : Implementation
If using an authentication token for a user session, ensure that the token lifetime is configured based on the recommended best practices from the token provider [REF-1563]. There are situations using authentication tokens such as a JWT (Java Web Token) in which the server-side does not handle session timeouts and trusts the values directly from the token. In this case, it is important that the timeout value is set correctly for the token that is granted.
Vulnerability Mapping Notes
Justification : 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.
Comment :
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.
Do not map to this CWE in situations where the timeout value is set, but the session is incorrectly invalidated; use CWE-1464 instead.
Notes
This entry was created in CWE 5.0 to address known gaps in CWE coverage. It is not as complete as other new entries that were published in recent years. The CWE Team plans to work with the CWE community to make this entry more complete in later 5.x releases.
