Last modified

CVE-2020-1669 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. The Juniper Device Manager (JDM) container, used by the disaggregated Junos OS architecture on Juniper Networks NFX350 Series devices, stores password hashes in the world-readable file /etc/passwd. This is not a security best current practice as it can allow an attacker with access to the local filesystem the ability to brute-force decrypt password hashes stored on the system. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
