CVE-2020-1624

Credential-material disclosure via readable objmon files

Published Apr 8, 2020 · Updated Sep 17, 2024

Information exposure in Juniper Networks Junos OS Evolved before 19.1R1 allows local users to read password hashes and shared secrets. The objmon logging path writes hashed login passwords and shared secrets into raw configuration files that low-privilege shell users can read. Exploitation requires an authenticated account with shell access; the disclosed consequence is retrieval of stored credential material, not plaintext passwords.
