CVE-2022-45047

Apache MINA SSHD: Java unsafe deserialization vulnerability

Published Nov 16, 2022 CVSS 3.1 · 9.8 Critical EPSS 3.8% KEV · Not listed
Description
Class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD <= 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. The class is one of several implementations that an implementor using Apache MINA SSHD can choose for loading the host keys of an SSH server.

Remediation

Vendor Workaround

For Apache MINA SSHD <= 2.9.1, do not use org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider to generate and later load your server's host key. Use separately generated host key files, for instance in OpenSSH format, and load them via a org.apache.sshd.common.keyprovider.FileKeyPairProvider instead. Or use a custom implementation instead of SimpleGeneratorHostKeyProvider that uses the OpenSSH format for storing and loading the host key (via classes OpenSSHKeyPairResourceWriter and OpenSSHKeyPairResourceParser).
