Netty is a network application framework for development of protocol servers and clients. In versions 4.2.0.Final through 4.2.15.Final and prior to 4.1.135.Final, `OcspClient` does not validate that the `CertificateID` in an OCSP response matches the requested `CertificateID`, which can lead to replay attack. `OcspClient.validateResponse` accepts a legitimately signed `GOOD` status response for an unrelated certificate issued by the same CA, allowing bypass of revocation checks for another certificate. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.

Affected: Maven: io.netty:netty-handler-ssl-ocsp

### Summary Netty's OcspClient does not validate that the CertificateID in an OCSP response matches the requested CertificateID. A bad actor can replay a `GOOD` status response issued for an unrelated certificate (by the same CA) to bypass revocation checks for any certificate.

### Details `io.netty.handler.ssl.ocsp.OcspClient#validateResponse` fails to assert that the CertificateID within the returned `BasicOCSPResp` matches the original certificate being validated.

When `OcspClient.query(...)` executes, it builds an OCSP request using the victim certificate's serial number and issuer hash. It then sends this request and receives a response. While the client verifies the signature of the response against the trusted issuer (or a valid responder chain), it never checks the CertificateID inside the response payload.

A bad actor who has access to any other valid, non-revoked certificate issued by the same CA can obtain a legitimately signed OCSP response indicating that the unrelated certificate is `GOOD`. The bad actor can then return this valid response to the Netty client when it queries the status of any other certificate (e.g., a revoked certificate) issued by the same CA. Because the signature is valid (signed by the CA) and the CertificateID is ignored, the client will incorrectly accept the target certificate as valid.

As per https://datatracker.ietf.org/doc/html/rfc6960#section-3.2 we have:

Ein Angreifer kann mehrere Schwachstellen in Netty ausnutzen, um Sicherheitsprüfungen zu umgehen, Anfragen oder Header zu manipulieren, Zertifikatsprüfungen zu unterlaufen sowie einen Denial of Service zu verursachen.
