CVE-2024-39532

High-privilege disclosure via plaintext log entries

Published Jul 11, 2024 · Updated Jan 7, 2025

Sensitive-data exposure in Junos OS and Junos OS Evolved allows local users with high privileges to read another user's data from logs. A specific user operation writes sensitive information in plaintext to a specific log file, but Juniper has not identified the operation or file publicly. Exploitation requires high-privilege local access and another user's interaction, exposing the logged information across a changed security boundary.
