CVE-2023-48795 | 43 9bis, Apache, Apple and 40 more | 78 Kitty, Sshd, Sshj and 75 more | 2025-05-01 | 5.9 Medium |
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust. | ||||
CVE-2011-0766 | 2 Erlang, Ssh | 3 Crypto, Erlang\/otp, Ssh | 2025-04-11 | N/A |
The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time, which makes it easier for remote attackers to guess DSA host and SSH session keys. | ||||
CVE-2012-5975 | 2 Linux, Ssh | 2 Linux Kernel, Tectia Server | 2025-04-11 | N/A |
The SSH USERAUTH CHANGE REQUEST feature in SSH Tectia Server 6.0.4 through 6.0.20, 6.1.0 through 6.1.12, 6.2.0 through 6.2.5, and 6.3.0 through 6.3.2 on UNIX and Linux, when old-style password authentication is enabled, allows remote attackers to bypass authentication via a crafted session involving entry of blank passwords, as demonstrated by a root login session from a modified OpenSSH client with an added input_userauth_passwd_changereq call in sshconnect2.c. | ||||
CVE-2007-5616 | 3 Linux, Opengroup, Ssh | 4 Linux Kernel, Unix, Tectia Client and 1 more | 2025-04-09 | N/A |
ssh-signer in SSH Tectia Client and Server 5.x before 5.2.4, and 5.3.x before 5.3.6, on Unix and Linux allows local users to gain privileges via unspecified vectors. | ||||
CVE-2006-5484 | 1 Ssh | 4 Tectia Client, Tectia Connector, Tectia Manager and 1 more | 2025-04-09 | N/A |
SSH Tectia Client/Server/Connector 5.1.0 and earlier, Manager 2.2.0 and earlier, and other products, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents Tectia from correctly verifying X.509 and other certificates that use PKCS #1, a similar issue to CVE-2006-4339. | ||||
CVE-2008-5161 | 3 Openbsd, Redhat, Ssh | 6 Openssh, Enterprise Linux, Tectia Client and 3 more | 2025-04-09 | N/A |
Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors. | ||||
CVE-2007-2063 | 1 Ssh | 1 Tectia Server | 2025-04-09 | N/A |
SSH Tectia Server for IBM z/OS before 5.4.0 uses insecure world-writable permissions for (1) the server pid file, which allows local users to cause arbitrary processes to be stopped, or (2) when _BPX_BATCH_UMASK is missing from the environment, creates HFS files with insecure permissions, which allows local users to read or modify these files and have other unknown impact. | ||||
CVE-1999-1231 | 1 Ssh | 1 Ssh2 | 2025-04-03 | 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-1999-1085 | 1 Ssh | 1 Secure Shell | 2025-04-03 | 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-1999-0310 | 1 Ssh | 1 Ssh | 2025-04-03 | N/A |
SSH 1.2.25 on HP-UX allows access to new user accounts. | ||||

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-2001-0144 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2025-04-03 | 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-2001-0259 | 1 Ssh | 1 Ssh | 2025-04-03 | 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-2001-0361 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2025-04-03 | 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 | 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 | 2025-04-03 | 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-1999-0787 | 1 Ssh | 1 Ssh | 2025-04-03 | N/A |
The SSH authentication agent follows symlinks via a UNIX domain socket. | ||||
CVE-2001-0572 | 3 Openbsd, Redhat, Ssh | 3 Openssh, Linux, Ssh | 2025-04-03 | 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-2001-1475 | 1 Ssh | 1 Ssh | 2025-04-03 | 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-2001-0553 | 1 Ssh | 1 Secure Shell | 2025-04-03 | 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. |
