CVE-2001-1585: OpenBSD OpenSSH

Medium severity, CVSS 6.8. EPSS: 1.9% chance of exploitation in the next 30 days.

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.

Affected products

  • OpenBSD OpenSSH: version 2.3.1 only
