medium Nessus Plugin ID 283017

Synopsis

The remote MiracleLinux host is missing one or more security updates.

Description

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2025-10789:04 advisory.

 * CVE-2018-20685: fix a vulnerability scp client where a malicious server could bypass intended access restrictions and modify target directory permissions via crafted filenames
 * CVE-2019-6109: fix scp client where a malicious server could manipulate the client's progress display output due to missing character encoding
 * CVE-2019-6111: fix scp client vulnerability that allowed a malicious server to overwrite arbitrary files in the client's target directory, including subdirectories, when performing transfers CVE(s):
 CVE-2019-6109 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 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 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).

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
