Juniper Command Injection Junos Junos Os Evolved

Description

An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the CLI of Juniper Networks Junos OS and Junos OS Evolved allows a high privileged, local attacker to escalated their privileges to root. When a user provides specifically crafted arguments to the 'request system logout' command, these will be executed as root on the shell, which can completely compromise the device. This issue affects: Junos OS:  * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S8, * 22.2 versions before 22.2R3-S6, * 22.3 versions before 22.3R3-S3, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S1, * 23.4 versions before 23.4R1-S2, 23.4R2; Junos OS Evolved: * all versions before 22.4R3-S6-EVO, * 23.2-EVO versions before 23.2R2-S1-EVO, * 23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO.

Analysis

An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the CLI of Juniper Networks Junos OS and Junos OS Evolved allows a high privileged, local attacker to escalated their privileges to root.

When a user provides specifically crafted arguments to the 'request system logout' command, these will be executed as root on the shell, which can completely compromise the device. This issue affects:

Junos OS:

  • all versions before 21.2R3-S9,
  • 21.4 versions before 21.4R3-S8,
  • 22.2 versions before 22.2R3-S6,
  • 22.3 versions before 22.3R3-S3,
  • 22.4 versions before 22.4R3-S6,
  • 23.2 versions before 23.2R2-S1,
  • 23.4 versions before 23.4R1-S2, 23.4R2;

Junos OS Evolved:

  • all versions before 22.4R3-S6-EVO,
  • 23.2-EVO versions before 23.2R2-S1-EVO,
  • 23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO.

Technical Context

Command injection allows an attacker to execute arbitrary OS commands on the host system through a vulnerable application that passes user input to system shells. This vulnerability is classified as OS Command Injection (CWE-78).

Affected Products

Affected products: Juniper Junos

Remediation

Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
