{"id":"UBUNTU-CVE-2019-6111","details":"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).","modified":"2026-01-30T02:50:11.991403Z","published":"2019-01-14T00:00:00Z","related":["USN-3885-1","USN-3885-2"],"upstream":["CVE-2019-6111"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-6111"},{"type":"REPORT","url":"https://sintonen.fi/advisories/scp-client-multiple-vulnerabilities.txt"},{"type":"REPORT","url":"https://lists.mindrot.org/pipermail/openssh-unix-dev/2019-January/037459.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3885-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3885-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-6111"}],"affected":[{"package":{"name":"openssh","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/openssh@1:6.6p1-2ubuntu2.13?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:6.6p1-2ubuntu2.13"}]}],"versions":["1:6.2p2-6","1:6.2p2-6ubuntu1","1:6.4p1-1","1:6.4p1-2","1:6.5p1-1","1:6.5p1-2","1:6.5p1-3","1:6.5p1-4","1:6.5p1-6","1:6.6p1-1","1:6.6p1-2","1:6.6p1-2ubuntu1","1:6.6p1-2ubuntu2","1:6.6p1-2ubuntu2.2","1:6.6p1-2ubuntu2.3","1:6.6p1-2ubuntu2.4","1:6.6p1-2ubuntu2.6","1:6.6p1-2ubuntu2.7","1:6.6p1-2ubuntu2.8","1:6.6p1-2ubuntu2.10","1:6.6p1-2ubuntu2.11","1:6.6p1-2ubuntu2.12"],"ecosystem_specific":{"availability":"No
