GHSA-j7r7-7qmf-xq87: Jenkins SAML Plugin does not implement a replay cache
Jenkins SAML Plugin 4.583.vc68232f7018a_ and earlier does not implement a replay cache.
This allows attackers able to obtain information about the SAML authentication flow between a user’s web browser and Jenkins to replay those requests, authenticating to Jenkins as that user.
SAML Plugin 4.583.585.v22ccc1139f55 implements a replay cache that rejects replayed requests.
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.
