✅ Remediation
Red Hat Trusted Artifact Signer simplifies cryptographic signing and verifying of software artifacts such as container images, binaries and source code changes. It is a self-managed on-premise deployment of the Sigstore project available at https://sigstore.dev Platform Engineers, Software Developers and Security Professionals may use RHTAS to ensure the integrity, transparency and assurance of their organization's software supply chain. For details on using the operator, refer to the product documentation at https://access.redhat.com/documentation/en-us/red_hat_trusted_artifact_signer/1.4 You can find the release notes for this version of Red Hat Trusted Artifact Signer at https://access.redhat.com/documentation/en-us/red_hat_trusted_artifact_signer/1.4/html-single/release_notes/index Workaround: Restrict network access to the etcd TLS listener to only trusted clients and networks. Configure firewall rules to limit inbound connections to the etcd client port (default 2379) and peer port (default 2380) to authorized hosts. This reduces the attack surface by preventing untrusted network attackers from reaching the vulnerable service.
