Summary

An Authentication Bypass by Primary Weakness in the FTP server of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to get limited read-write access to files on the device. When the FTP server is enabled and a user named "ftp" or "anonymous" is configured, that user can login without providing the configured password and then has read-write access to their home directory.

Risk Assessment

An unauthenticated attacker can read and modify files on the device, potentially compromising confidentiality and integrity.

Recommendation

Disable the FTP server or remove the 'ftp' and 'anonymous' accounts, then update Junos OS to a fixed version (22.4R3-S8, 23.2R2-S3, 23.4R2 or later).
