15 Apr 2024 — In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is especially important in a scenario where an adversary is able to read messages signed by PuTTY or Pageant. The required set of signed messages may be publicly readable because they are stored in a public Git service that supports use of SSH for commit signing, and the signatures were made by Pageant through an agent-forw... • https://github.com/sh1k4ku/CVE-2024-31497 • CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) •

https://notcve.org/view.php?id=CVE-2023-48795
18 Dec 2023 — 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 phas... • https://packetstorm.news/files/id/176280 • CWE-222: Truncation of Security-relevant Information CWE-354: Improper Validation of Integrity Check Value •

27 Jan 2021 — WinSCP before 5.17.10 allows remote attackers to execute arbitrary programs when the URL handler encounters a crafted URL that loads session settings. (For example, this is exploitable in a default installation in which WinSCP is the handler for sftp:// URLs.) WinSCP anterior a la versión 5.17.10 permite a los atacantes remotos ejecutar programas arbitrarios cuando el manejador de URLs encuentra una URL manipulada que carga la configuración de la sesión.

CVSS: 6.8EPSS: 0%CPEs: 51EXPL: 0CVE-2019-6109 – openssh: Missing character encoding in progress display allows for spoofing of scp client output
https://notcve.org/view.php?id=CVE-2019-6109
16 Jan 2019 — 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. Se ha descubierto un problema en OpenSSH 7.9.

16 Jan 2019 — 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.

https://notcve.org/view.php?id=CVE-2019-6111
16 Jan 2019 — 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... • https://packetstorm.news/files/id/151227 • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

10 Jan 2019 — In WinSCP before 5.14 beta, due to missing validation, the scp implementation would accept arbitrary files sent by the server, potentially overwriting unrelated files. This affects TSCPFileSystem::SCPSink in core/ScpFileSystem.cpp. En WinSCP, en versiones anteriores a la 5.14 beta, debido a la falta de validación, la implementación de scp aceptaría archivos arbitrarios enviados por el servidor, lo que podría sobrescribir archivos no relacionados.

10 Jan 2019 — 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. En OpenSSH 7.9, scp.c en el cliente scp permite que los servidores SSH omitan las restricciones de acceso planeadas mediante un nombre de archivo "." o un nombre de archivo vacío.

16 Apr 2014 — WinSCP before 5.5.3, when FTP with TLS is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

06 Aug 2013 — Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow.
