CVE-2026-33785: CWE-862 Missing Authorization in Juniper Networks Junos OS
A Missing Authorization vulnerability in the CLI of Juniper Networks Junos OS on MX Series allows a local, authenticated user with low privileges to execute specific commands which will lead to a complete compromise of managed devices. Any user logged in, without requiring specific privileges, can issue 'request csds' CLI operational commands. These commands are only meant to be executed by high privileged or users designated for Juniper Device Manager (JDM) / Connected Security Distributed Services (CSDS) operations as they will impact all aspects of the devices managed via the respective MX. This issue affects Junos OS on MX Series: * 24.4 releases before 24.4R2-S3, * 25.2 releases before 25.2R2. This issue does not affect Junos OS releases before 24.4.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-33785) in Juniper Networks Junos OS on MX Series is due to missing authorization checks in the CLI. Specifically, any authenticated user with low privileges can issue 'request csds' operational commands intended only for high-privileged users or those designated for Juniper Device Manager (JDM) / Connected Security Distributed Services (CSDS) operations. These commands impact all aspects of devices managed via the MX Series, potentially leading to full device compromise. Affected versions include 24.4 releases before 24.4R2-S3 and 25.2 releases before 25.2R2. Juniper manages remediation for this cloud-hosted service, and a patch is available.
Potential Impact
An attacker with low-level authenticated access can execute privileged commands that affect all managed devices, resulting in complete compromise of those devices. The vulnerability allows unauthorized command execution with high impact on confidentiality, integrity, and availability (CVSS 8.8). No known exploits are currently reported in the wild.
Mitigation Recommendations
A patch is available for this vulnerability. Since Junos OS on MX Series is a cloud-hosted service, Juniper Networks manages remediation server-side. Users should verify with Juniper's official advisory and ensure their systems are updated to versions 24.4R2-S3 or later, or 25.2R2 or later to mitigate this issue.
