CVE-2025-21592

Junos OS: SRX Series: Low privileged user able to access highly sensitive information on file system

Description

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the command-line interface (CLI) of Juniper Networks Junos OS on SRX Series devices allows a local, low-privileged user with access to the Junos CLI to view the contents of sensitive files on the file system. Through the execution of either 'show services advanced-anti-malware' or 'show services security-intelligence' command, a user with limited permissions (e.g., a low privilege login class user) can access protected files that should not be accessible to the user. These files may contain sensitive information that can be used to cause further impact to the system. This issue affects Junos OS SRX Series: * All versions before 21.4R3-S8, * from 22.2 before 22.2R3-S5, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R2.

Remediation

Solution:

  • The following software releases have been updated to resolve this specific issue: 21.4R3-S8, 22.2R3-S5, 22.3R3-S3, 22.4R3-S2, 23.2R2-S1, 23.4R2, 24.2R1, and all subsequent releases.

Workaround:

  • Use access lists or firewall filters to limit access to the CLI only from trusted hosts and administrators. Use command authorisation to limit access to the 'show services advanced-anti-malware' and 'show services security-intelligence' commands. Although not a workaround, but if the Advanced Anti-Malware and Security Intelligence features are not used, they can be disabled using below commands to avoid the vulnerability. [ system processes advanced-anti-malware disable ] [ system processes security-intelligence disable ]
