org.apache.sshd/sshd-core: Apache MINA SSHD: Authentication bypass via duplicate public key presentation

A flaw was found in Apache MINA SSHD. When the server is configured to require multiple Secure Shell SSH public keys for authentication, it fails to verify that the submitted keys are distinct. A remote user can exploit this flaw by presenting the same public key twice to satisfy multi-key...

org.apache.sshd/sshd-core: Apache MINA SSHD: Asynchronous authentication can bypass signature verification

A flaw was found in Apache MINA SSHD. When a Secure Shell SSH server implements the asynchronous authentication feature, a logic error in signature verification can result in public-key or host-based authentication checks being skipped. A remote, unauthenticated attacker can exploit this flaw to...
