| CVE-2001-0471 | SSH daemon version 1 (aka SSHD-1 or SSH-1) 1.2.30 and earlier does not log repeated login attempts, which could allow remote attackers to compromise accounts without detection via a brute force attack. | [email protected] | 7.5 | 5.57% | 2001-06-27 | 2026-06-16 |
| CVE-2001-0364 | SSH Communications Security sshd 2.4 for Windows allows remote attackers to create a denial of service via a large number of simultaneous connections. | [email protected] | 5.0 | 1.61% | 2001-06-27 | 2026-06-16 |
| CVE-2001-0361 | Implementations of SSH version 1.5, including (1) OpenSSH up to version 2.3.0, (2) AppGate, and (3) ssh-1 up to version 1.2.31, in certain configurations, allow a remote attacker to decrypt and/or alter traffic via a "Bleichenbacher attack" on PKCS#1 version 1.5. | [email protected] | 4.0 | 2.84% | 2001-06-27 | 2026-06-16 |
| CVE-2001-0259 | ssh-keygen in ssh 1.2.27 - 1.2.30 with Secure-RPC can allow local attackers to recover a SUN-DES-1 magic phrase generated by another user, which the attacker can use to decrypt that user's private key file. | [email protected] | 3.6 | 0.84% | 2001-06-02 | 2026-06-16 |
| CVE-2001-0144 | CORE SDI SSH1 CRC-32 compensation attack detector allows remote attackers to execute arbitrary commands on an SSH server or client via an integer overflow. | [email protected] | 10.0 | 32.42% | 2001-03-12 | 2026-06-16 |
| CVE-2001-1476 | SSH before 2.0, with RC4 encryption and the "disallow NULL passwords" option enabled, makes it easier for remote attackers to guess portions of user passwords by replaying user sessions with certain modifications, which trigger different messages depending on whether the guess is correct or not. | [email protected] | 7.5 | 1.01% | 2001-01-18 | 2026-06-16 |
| CVE-2001-1475 | SSH before 2.0, when using RC4 and password authentication, allows remote attackers to replay messages until a new server key (VK) is generated. | [email protected] | 7.5 | 1.54% | 2001-01-18 | 2026-06-16 |
| CVE-2001-1474 | SSH before 2.0 disables host key checking when connecting to the localhost, which allows remote attackers to silently redirect connections to the localhost by poisoning the client's DNS cache. | [email protected] | 5.0 | 1.17% | 2001-01-18 | 2026-06-16 |
| CVE-2001-1473 | The SSH-1 protocol allows remote servers to conduct man-in-the-middle attacks and replay a client challenge response to a target server by creating a Session ID that matches the Session ID of the target, but which uses a public key pair that is weaker than the target's public key, which allows the attacker to compute the corresponding private key and use the target's Session ID with the compromised key pair to masquerade as the target. | [email protected] | 7.5 | 6.27% | 2001-01-18 | 2026-06-16 |
| CVE-2001-1470 | The IDEA cipher as implemented by SSH1 does not protect the final block of a message against modification, which allows remote attackers to modify the block without detection by changing its cyclic redundancy check (CRC) to match the modifications to the message. | [email protected] | 5.0 | 1.15% | 2001-01-18 | 2026-06-16 |
| CVE-2001-1469 | The RC4 stream cipher as used by SSH1 allows remote attackers to modify messages without detection by XORing the original message's cyclic redundancy check (CRC) with the CRC of a mask consisting of all the bits of the original message that were modified. | [email protected] | 5.0 | 1.21% | 2001-01-18 | 2026-06-16 |

| CVE-2000-0575 | SSH 1.2.27 with Kerberos authentication support stores Kerberos tickets in a file which is created in the current directory of the user who is logging in, which could allow remote attackers to sniff the ticket cache if the home directory is installed on NFS. | [email protected] | 7.2 | 0.85% | 2000-07-05 | 2026-06-16 |
| CVE-2000-0217 | The default configuration of SSH allows X forwarding, which could allow a remote attacker to control a client's X sessions via a malicious xauth program. | [email protected] | 5.1 | 0.97% | 2000-02-24 | 2026-06-16 |
| CVE-2000-0143 | The SSH protocol server sshd allows local users without shell access to redirect a TCP connection through a service that uses the standard system password database for authentication, such as POP or FTP. | [email protected] | 4.6 | 0.35% | 2000-02-11 | 2026-06-16 |
