If you cannot patch yet, consider restricting network access to trusted devices and monitoring for suspicious SSH activity related to Apstra-managed devices.
Description
Juniper Networks Apstra versions before 6.1.1 contain a vulnerability in their SSH implementation where key exchange occurs without proper entity authentication. This flaw allows an unauthenticated attacker to perform a man-in-the-middle attack by impersonating managed devices. The attacker can intercept SSH connections from Apstra to managed devices, potentially capturing user credentials. The vulnerability is identified as CWE-322 and has a high severity rating with a CVSS score of 8.7.
