CVE-2019-6109 (GCVE-0-2019-6109)

Vulnerability from cvelistv5 – Published: 2019-01-31 00:00 – Updated: 2026-05-28 18:13

Summary

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.

Severity

6.8 (Medium)

CVE-2019-6111 (GCVE-0-2019-6111)

Vulnerability from cvelistv5 – Published: 2019-01-31 00:00 – Updated: 2025-12-18 14:35

Summary

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).

Severity

A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory.
