CVE-2001-1380 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
OpenSSH before 2.9.9, while using keypairs and multiple keys of different types in the ~/.ssh/authorized_keys2 file, may not properly handle the "from" option associated with a key, which could allow remote attackers to login from unauthorized IP addresses. | |||||
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-2006-0883 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2025-04-03 | 5.0 MEDIUM | N/A |
OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting. | |||||
CVE-2005-2797 | 1 Openbsd | 1 Openssh | 2025-04-03 | 5.0 MEDIUM | N/A |
OpenSSH 4.0, and other versions before 4.2, does not properly handle dynamic port forwarding ("-D" option) when a listen address is not provided, which may cause OpenSSH to enable the GatewayPorts functionality. | |||||
CVE-2004-1653 | 1 Openbsd | 1 Openssh | 2025-04-03 | 6.4 MEDIUM | N/A |
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS. | |||||
CVE-2005-2798 | 1 Openbsd | 1 Openssh | 2025-04-03 | 5.0 MEDIUM | N/A |
sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts. | |||||
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-1999-1010 | 1 Openbsd | 1 Openssh | 2025-04-03 | 2.1 LOW | N/A |
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy. | |||||
CVE-2001-1459 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, which allows local users to bypass resource limits (rlimits) set in pam.d. | |||||
CVE-2003-0695 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using (1) buffer_init in buffer.c, (2) buffer_free in buffer.c, or (3) a separate function in channels.c, a different vulnerability than CVE-2003-0693. | |||||
CVE-2001-1507 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.5 HIGH | N/A |
OpenSSH before 3.0.1 with Kerberos V enabled does not properly authenticate users, which could allow remote attackers to login unchallenged. | |||||
CVE-2003-1562 | 1 Openbsd | 1 Openssh | 2025-04-03 | 7.6 HIGH | N/A |
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190. | |||||
CVE-2001-1382 | 1 Openbsd | 1 Openssh | 2025-04-03 | 5.0 MEDIUM | N/A |
The "echo simulation" traffic analysis countermeasure in OpenSSH before 2.9.9p2 sends an additional echo packet after the password and carriage return is entered, which could allow remote attackers to determine that the countermeasure is being used. | |||||
CVE-2004-0175 | 1 Openbsd | 1 Openssh | 2025-04-03 | 4.3 MEDIUM | N/A |
Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992. | |||||
CVE-2001-1029 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2025-04-03 | 2.1 LOW | N/A |
libutil in OpenSSH on FreeBSD 4.4 and earlier does not drop privileges before verifying the capabilities for reading the copyright and welcome files, which allows local users to bypass the capabilities checks and read arbitrary files by specifying alternate copyright or welcome files. | |||||
CVE-2023-48795 | 43 9bis, Apache, Apple and 40 more | 69 Kitty, Sshd, Sshj and 66 more | 2024-12-02 | N/A | 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-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2024-11-21 | N/A | 7.0 HIGH |
OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. | |||||
CVE-2023-51385 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 6.5 MEDIUM |
In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name. | |||||
CVE-2023-51384 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2024-11-21 | N/A | 5.5 MEDIUM |
In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys. | |||||
CVE-2023-38408 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2024-11-21 | N/A | 9.8 CRITICAL |
The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. |
