CVE-2003-1119 1 Ssh 1 Secure Shell 2025-04-03 5.0 MEDIUM N/A
SSH Secure Shell before 3.2.9 allows remote attackers to cause a denial of service via malformed BER/DER packets.
CVE-2001-1469 1 Ssh 1 Ssh 2025-04-03 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-2001-0364 1 Ssh 1 Ssh2 2025-04-03 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-2005-2146 1 Ssh 1 Tectia Server 2025-04-03 4.6 MEDIUM N/A
SSH Tectia Server 4.3.1 and earlier, and SSH Secure Shell for Windows Servers, uses insecure permissions when generating the Secure Shell host identification key, which allows local users to access the key and spoof the server.
CVE-1999-1085 1 Ssh 1 Secure Shell 2025-04-03 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."
CVE-2005-4310 1 Ssh 1 Tectia Server 2025-04-03 7.5 HIGH N/A
SSH Tectia Server 5.0.0 (A, F, and T), when allowing host-based authentication only, allows users to log in with the wrong credentials.
CVE-2002-1644 1 Ssh 1 Ssh2 2025-04-03 7.2 HIGH N/A
SSH Secure Shell for Servers and SSH Secure Shell for Workstations 2.0.13 through 3.2.1, when running without a PTY, does not call setsid to remove the child process from the process group of the parent process, which allows attackers to gain certain privileges.
CVE-2002-1646 1 Ssh 1 Secure Shell For Servers 2025-04-03 7.5 HIGH N/A
SSH Secure Shell for Servers 3.0.0 to 3.1.1 allows remote attackers to override the AllowedAuthentications configuration and use less secure authentication schemes (e.g. password) than configured for the server.
CVE-2001-1474 1 Ssh 1 Ssh 2025-04-03 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-1999-1159 1 Ssh 1 Ssh2 2025-04-03 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-2001-1475 1 Ssh 1 Ssh 2025-04-03 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-2001-1470 1 Ssh 1 Ssh 2025-04-03 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-1999-0787 1 Ssh 1 Ssh 2025-04-03 2.1 LOW N/A
The SSH authentication agent follows symlinks via a UNIX domain socket.
CVE-1999-1231 1 Ssh 1 Ssh2 2025-04-03 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-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 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-2000-0992 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 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-2001-0572 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 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-2001-0361 2 Openbsd, Ssh 2 Openssh, Ssh 2025-04-03 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-2000-0575 1 Ssh 1 Ssh 2025-04-03 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-2003-1120 1 Ssh 1 Tectia Server 2025-04-03 3.7 LOW N/A
Race condition in SSH Tectia Server 4.0.3 and 4.0.4 for Unix, when the password change plugin (ssh-passwd-plugin) is enabled, allows local users to obtain the server's private key.
