CVE-2019-6110 4 Netapp, Openbsd, Siemens and 1 more 9 Element Software, Ontap Select Deploy, Storage Automation Store and 6 more 2023-02-23 4.0 MEDIUM 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 2023-02-23 4.0 MEDIUM 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-2018-20685 9 Canonical, Debian, Fujitsu and 6 more 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more 2023-02-23 2.6 LOW 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-2019-6111 5 Canonical, Debian, Openbsd and 2 more 5 Ubuntu Linux, Debian Linux, Openssh and 2 more 2022-12-13 5.8 MEDIUM 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-2013-4852 5 Debian, Opensuse, Putty and 2 more 5 Debian Linux, Opensuse, Putty and 2 more 2021-08-06 6.8 MEDIUM N/A
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.
CVE-2021-3331 1 Winscp 1 Winscp 2021-02-04 10.0 HIGH 9.8 CRITICAL
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.)
CVE-2020-28864 1 Winscp 1 Winscp 2020-12-02 7.5 HIGH 9.8 CRITICAL
Buffer overflow in WinSCP 5.17.8 allows a malicious FTP server to cause a denial of service or possibly have other unspecified impact via a long file name.
CVE-2018-20684 1 Winscp 1 Winscp 2020-01-15 6.4 MEDIUM 7.5 HIGH
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.
CVE-2007-4909 1 Winscp 1 Winscp 2018-10-15 9.3 HIGH N/A
Interpretation conflict in WinSCP before 4.0.4 allows remote attackers to perform arbitrary file transfers with a remote server via file-transfer commands in the final portion of a (1) scp, and possibly a (2) sftp or (3) ftp, URL, as demonstrated by a URL specifying login to the remote server with a username of scp, which is interpreted as an HTTP scheme name by the protocol handler in a web browser, but is interpreted as a username by WinSCP. NOTE: this is related to an incomplete fix for CVE-2006-3015.
CVE-2014-2735 1 Winscp 1 Winscp 2018-10-09 5.8 MEDIUM N/A
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.
CVE-2002-1360 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2017-10-10 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2002-1359 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2017-10-10 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2002-1358 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2017-10-10 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2002-1357 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2017-10-10 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2006-3015 1 Winscp 1 Winscp 2017-07-19 7.1 HIGH N/A
Argument injection vulnerability in WinSCP 3.8.1 build 328 allows remote attackers to upload or download arbitrary files via encoded spaces and double-quote characters in a scp or sftp URI.
