    descriptionAn issue was discovered in OpenSSH. 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-2019-6111) In OpenSSH, 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-2018-20685) An issue was discovered in OpenSSH. 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-2019-6109 )

    descriptionAccording to the versions of the openssh packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - 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-2017-15906) - 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-2018-20685) - An issue was discovered in OpenSSH 7.9.

If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).(CVE-2019-6111) - 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-2018-15473) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

    descriptionMultiple scp client vulnerabilities have been discovered in OpenSSH, the premier connectivity tool for secure remote shell login and secure file transfer. CVE-2018-20685 In scp.c, the scp client allowed remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact was modifying the permissions of the target directory on the client side. CVE-2019-6109 Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) was able to employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affected refresh_progress_meter() in progressmeter.c. CVE-2019-6111 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 performed cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) was able to overwrite arbitrary files in the scp client target directory. If recursive operation (-r) was performed, the server was able to manipulate subdirectories, as well (for example, to overwrite the .ssh/authorized_keys file). For Debian 8

    descriptionHarry Sintonen from F-Secure Corporation discovered multiple vulnerabilities in OpenSSH, an implementation of the SSH protocol suite. All the vulnerabilities are in found in the scp client implementing the SCP protocol. - CVE-2018-20685 Due to improper directory name validation, the scp client allows servers to modify permissions of the target directory by using empty or dot directory name. - CVE-2019-6109 Due to missing character encoding in the progress display, the object name can be used to manipulate the client output, for example to employ ANSI codes to hide additional files being transferred. - CVE-2019-6111 Due to scp client insufficient input validation in path names sent by server, a malicious server can do arbitrary file overwrites in target directory. If the recursive (-r) option is provided, the server can also manipulate subdirectories as well. The check added in this version can lead to regression if the client and the server have differences in wildcard expansion rules. If the server is trusted for that purpose, the check can be disabled with a new -T option to the scp client.
