CVE-2025-30654 in Junos OS
Summary
by MITRE • 04/09/2025
An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the User Interface (UI) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged, authenticated attacker with access to the CLI to access sensitive information.
Through the execution of a specific show mgd command, a user with limited permissions (e.g., a low-privileged login class user) can access sensitive information such as hashed passwords, that can be used to further impact the system.
This issue affects Junos OS: * All versions before 21.4R3-S10, * from 22.2 before 22.2R3-S5, * from 22.4 before 22.4R3-S5, * from 23.2 before 23.2R2-S3, * from 23.4 before 23.4R2-S3.
Junos OS Evolved:
* All versions before 21.4R3-S10-EVO, * from 22.2-EVO before 22.2R3-S6-EVO, * from 22.4-EVO before 22.4R3-S5-EVO, * from 23.2-EVO before 23.2R2-S3-EVO, * from 23.4-EVO before 23.4R2-S3-EVO.

The vulnerability identified as CVE-2025-30654 represents a critical exposure of sensitive information to unauthorized actors within the user interface of Juniper Networks Junos OS and Junos OS Evolved platforms. This weakness manifests as an information disclosure flaw that specifically affects low-privileged authenticated users with access to the command-line interface. The vulnerability stems from inadequate access controls and privilege separation mechanisms within the show mgd command implementation, which allows unauthorized users to extract sensitive data that should remain restricted to administrative personnel. The flaw demonstrates a clear violation of the principle of least privilege and represents a significant security regression in the platform's information protection mechanisms.
The technical exploitation of this vulnerability occurs through the execution of a specific show mgd command that bypasses normal authentication and authorization checks. This command reveals hashed passwords and other sensitive information that would typically be restricted to high-privileged users with administrative access rights. The implementation flaw allows any user with a valid login class account to execute this command and gain access to information that should be protected by proper access controls. This represents a classic case of insufficient authorization checks and inadequate privilege validation, where the system fails to properly verify user credentials against the required security context before exposing sensitive data. The vulnerability is particularly concerning because it operates at the command-line interface level, where users typically expect to have controlled access to system information based on their assigned permissions.
From an operational impact perspective, this vulnerability creates a substantial risk to network security infrastructure managed by Juniper devices. The exposure of hashed passwords provides attackers with potential credentials that could be used for further system compromise, lateral movement, or credential reuse attacks. The vulnerability affects multiple version ranges across both Junos OS and Junos OS Evolved platforms, indicating a widespread issue that requires immediate attention from network administrators. The impact extends beyond simple information disclosure as it enables attackers to escalate their privileges and potentially gain full administrative control of affected devices. This vulnerability aligns with CWE-200 (Information Exposure) and represents a significant concern for organizations that rely on Juniper networking equipment for critical infrastructure protection.
Network security professionals must prioritize immediate remediation of this vulnerability through the application of appropriate software patches and updates. The affected versions span multiple release branches, requiring careful coordination of patch management activities across different device types and software versions. Organizations should implement monitoring for unauthorized command execution attempts and review access control configurations to minimize potential exploitation opportunities. The vulnerability also highlights the importance of proper privilege separation and access control enforcement within network operating systems. Security teams should conduct comprehensive assessments of their Juniper device configurations and implement additional controls to detect and prevent unauthorized access attempts. This issue demonstrates the critical need for regular security assessments and the importance of maintaining current software versions to protect against known vulnerabilities. The ATT&CK framework categorizes this as a privilege escalation technique through credential access, where attackers exploit information disclosure to gain unauthorized access to sensitive system information.
