Ory fosite contains Improper Handling of Exceptional Conditions

High severity GitHub Reviewed Published Sep 24, 2020 in ory/fosite • Updated Feb 14, 2023

Package

gomod github.com/ory/fosite (Go)

Affected versions

< 0.34.0

Patched versions

0.34.0

Description

Impact

The TokenRevocationHandler ignores errors coming from the storage. This can lead to unexpected 200 status codes indicating successful revocation while the token is still valid. Whether an attacker can use this for her advantage depends on the ability to trigger errors in the store.

References

RFC 7009 states that a 503 HTTP code must be returned when the server has a problem.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
