The network device must not allow SSH Version 1 to be used for administrative access.


Overview

Finding ID Version Rule ID IA Controls Severity
V-14717 NET1647 SV-15459r4_rule Medium
Description
SSH Version 1 is a protocol that has never been defined in a standard. Since SSH-1 has inherent design flaws which make it vulnerable to attacks, e.g., man-in-the-middle attacks, it is now generally considered obsolete and should be avoided by explicitly disabling fallback to SSH-1.
