CVE-2025-21592 | Junos OS: SRX Series: Low privileged user able to access highly sensitive information on file system

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.

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
