Name of the Vulnerable Software and Affected Versions: Junos OS Evolved versions prior to 19.3R1

Description: The issue is related to insufficient protection of registration data in the configd Streamer Log component of the JunOS Evolved operating system. Exploitation of this issue may allow an attacker to gain unauthorized access to protected information. A local, authenticated user with shell access can obtain the hashed values of login passwords via the configd streamer log.

Recommendations: For versions prior to 19.3R1, update to version 19.3R1 or later to resolve the issue. As a temporary workaround, consider restricting access to the configd streamer log to minimize the risk of exploitation. Avoid using the configd streamer log feature until the issue is resolved.
