CVE-2001-1476 1 Ssh 1 Ssh 2024-11-20 7.5 HIGH N/A
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.
CVE-2001-1475 1 Ssh 1 Ssh 2024-11-20 7.5 HIGH N/A
SSH before 2.0, when using RC4 and password authentication, allows remote attackers to replay messages until a new server key (VK) is generated.
CVE-2001-1474 1 Ssh 1 Ssh 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2001-1473 1 Ssh 1 Ssh 2024-11-20 7.5 HIGH N/A
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.
CVE-2001-1470 1 Ssh 1 Ssh 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2001-1469 1 Ssh 1 Ssh 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2001-0572 2 Openbsd, Ssh 2 Openssh, Ssh 2024-11-20 7.5 HIGH N/A
The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands.
CVE-2001-0553 1 Ssh 1 Secure Shell 2024-11-20 7.2 HIGH N/A
SSH Secure Shell 3.0.0 on Unix systems does not properly perform password authentication to the sshd2 daemon, which allows local users to gain access to accounts with short password fields, such as locked accounts that use "NP" in the password field.
CVE-2001-0471 1 Ssh 1 Ssh 2024-11-20 7.5 HIGH N/A
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.
CVE-2001-0364 1 Ssh 1 Ssh2 2024-11-20 5.0 MEDIUM N/A
SSH Communications Security sshd 2.4 for Windows allows remote attackers to create a denial of service via a large number of simultaneous connections.
CVE-2001-0361 2 Openbsd, Ssh 2 Openssh, Ssh 2024-11-20 4.0 MEDIUM N/A
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.
CVE-2001-0259 1 Ssh 1 Ssh 2024-11-20 3.6 LOW N/A
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.
CVE-2001-0144 2 Openbsd, Ssh 2 Openssh, Ssh 2024-11-20 10.0 HIGH N/A
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.
CVE-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2024-11-20 5.0 MEDIUM N/A
Directory traversal vulnerability in scp in sshd 1.2.xx allows a remote malicious scp server to overwrite arbitrary files via a .. (dot dot) attack.
CVE-2000-0575 1 Ssh 1 Ssh 2024-11-20 7.2 HIGH N/A
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.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2024-11-20 5.1 MEDIUM N/A
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.
CVE-2000-0143 2 Openbsd, Ssh 2 Openssh, Ssh 2024-11-20 4.6 MEDIUM N/A
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.
CVE-1999-1231 1 Ssh 1 Ssh2 2024-11-20 5.0 MEDIUM N/A
ssh 2.0.12, and possibly other versions, allows valid user names to attempt to enter the correct password multiple times, but only prompts an invalid user name for a password once, which allows remote attackers to determine user account names on the server.
CVE-1999-1159 1 Ssh 1 Ssh2 2024-11-20 4.6 MEDIUM N/A
SSH 2.0.11 and earlier allows local users to request remote forwarding from privileged ports without being root.
CVE-1999-1085 1 Ssh 1 Secure Shell 2024-11-20 5.0 MEDIUM N/A
SSH 1.2.25, 1.2.23, and other versions, when used in in CBC (Cipher Block Chaining) or CFB (Cipher Feedback 64 bits) modes, allows remote attackers to insert arbitrary data into an existing stream between an SSH client and server by using a known plaintext attack and computing a valid CRC-32 checksum for the packet, aka the "SSH insertion attack."
