Description

A Key Exchange without Entity Authentication vulnerability in the SSH implementation of Juniper Networks Apstra allows a unauthenticated, MITM

attacker to impersonate managed devices.

Due to insufficient SSH host key validation an attacker can perform a machine-in-the-middle attack on the SSH connections from Apstra to managed devices, enabling an attacker to impersonate a managed device and capture user credentials.

This issue affects all versions of Apstra before 6.1.1.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity high, availability none.
