CVE-2026-56820

Описание

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.

A flaw was found in Netty. The `OcspClient` component fails to validate that the Certificate ID in an Online Certificate Status Protocol (OCSP) response matches the requested Certificate ID. This vulnerability allows a remote attacker to bypass certificate revocation checks by presenting a legitimately signed OCSP response for an unrelated certificate issued by the same Certificate Authority, leading to a replay attack. This can result in the acceptance of revoked certificates, potentially compromising the integrity and confidentiality of communications.
