OpenSSH 2.3.1 Development Snapshot Vulnerability: Bypassing Authentication via SSH-2 Public Key

CVE-2001-1585 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

SSH protocol 2 (aka SSH-2) public key authentication in the development snapshot of OpenSSH 2.3.1, available from 2001-01-18 through 2001-02-08, does not perform a challenge-response step to ensure that the client has the proper private key, which allows remote attackers to bypass authentication as other users by supplying a public key from that user's authorized_keys file.
