AI-suggested
To mitigate CVE-2025-52988, organizations should immediately identify all Juniper Networks devices running affected Junos OS or Junos OS Evolved versions. Applying the vendor-provided patches for the specific versions listed is the most effective mitigation. Until patches are deployed, restrict local access to trusted administrators only and enforce strict privilege separation to minimize the number of users with high privileges capable of executing the vulnerable command. Implement robust monitoring and alerting for unusual CLI command usage, especially the 'request system logout' command with unexpected arguments. Consider disabling or restricting CLI commands that are not essential to reduce attack surface. Employ network segmentation to isolate management interfaces and limit exposure. Regularly audit user accounts and privileges to detect and remove unnecessary high-privilege access. Maintain up-to-date backups and incident response plans to quickly recover from potential compromises. Finally, stay informed on Juniper’s security advisories for any updates or additional mitigations.
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.
