| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2024-11-21 | 7.1 High |
| ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. | ||||
| CVE-2020-15778 | 4 Broadcom, Netapp, Openbsd and 1 more | 11 Fabric Operating System, A700s, A700s Firmware and 8 more | 2024-11-21 | 7.8 High |
| scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." | ||||
| CVE-2020-14145 | 3 Netapp, Openbsd, Redhat | 11 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 8 more | 2024-11-21 | 5.9 Medium |
| The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected. | ||||
| CVE-2020-12062 | 1 Openbsd | 1 Openssh | 2024-11-21 | 7.5 High |
| The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that "this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol" and "utimes does not fail under normal circumstances. | ||||
| CVE-2019-6111 | 10 Apache, Canonical, Debian and 7 more | 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more | 2024-11-21 | 5.9 Medium |
| An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). | ||||
| CVE-2019-6110 | 4 Netapp, Openbsd, Siemens and 1 more | 9 Element Software, Ontap Select Deploy, Storage Automation Store and 6 more | 2024-11-21 | 6.8 Medium |
| In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred. | ||||
| CVE-2019-6109 | 9 Canonical, Debian, Fedoraproject and 6 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2024-11-21 | 6.8 Medium |
| An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c. | ||||
| CVE-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2024-11-21 | 7.8 High |
| OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. | ||||
| CVE-2018-20685 | 9 Canonical, Debian, Fujitsu and 6 more | 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more | 2024-11-21 | 5.3 Medium |
| In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. | ||||
| CVE-2018-15919 | 2 Netapp, Openbsd | 7 Cloud Backup, Cn1610, Cn1610 Firmware and 4 more | 2024-11-21 | N/A |
| Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' | ||||
| CVE-2018-15473 | 7 Canonical, Debian, Netapp and 4 more | 25 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 22 more | 2024-11-21 | 5.3 Medium |
| OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. | ||||
| CVE-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 23 Debian Linux, Active Iq Unified Manager, Cloud Backup and 20 more | 2024-11-21 | 5.3 Medium |
| The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. | ||||
| CVE-2016-6210 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2024-11-21 | N/A |
| sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided. | ||||
| CVE-2016-20012 | 2 Netapp, Openbsd | 5 Clustered Data Ontap, Hci Management Node, Ontap Select Deploy Administration Utility and 2 more | 2024-11-21 | 5.3 Medium |
| OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product | ||||
| CVE-2016-1908 | 4 Debian, Openbsd, Oracle and 1 more | 10 Debian Linux, Openssh, Linux and 7 more | 2024-11-21 | 9.8 Critical |
| The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | ||||
| CVE-2016-10708 | 5 Canonical, Debian, Netapp and 2 more | 13 Ubuntu Linux, Debian Linux, Cloud Backup and 10 more | 2024-11-21 | N/A |
| sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | ||||
