CVE-2019-6110 EXPLOITDB MEDIUM python WORKING POC
OpenSSH < 7.9 - Terminal Output Manipulation via ANSI Control Codes
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-2019-6111 EXPLOITDB MEDIUM python WORKING POC
OpenSSH < 7.9 - Arbitrary File Write via Malicious SCP Server
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).
