CVE-2026-33776: CWE-862 Missing Authorization in Juniper Networks Junos OS
A Missing Authorization vulnerability in the CLI of Juniper Networks Junos OS and Junos OS Evolved allows a local user with low privileges to read sensitive information. A local user with low privileges can execute the CLI command 'show mgd' with specific arguments which will expose sensitive information. This issue affects Junos OS: * all versions before 22.4R3-S8, * 23.2 versions before 23.2R2-S6, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S4, * 24.4 versions before 24.4R2-S1, * 25.2 version before 25.2R1-S2, 25.2R2; Junos OS Evolved: * all versions before 23.2R2-S6-EVO, * 23.4 version before 23.4R2-S6-EVO, * 24.2 version before 24.2R2-S4-EVO, * 24.4 versions before 24.4R2-S1-EVO, * 25.2 versions before 25.2R2-EVO.
AI Analysis
Technical Summary
This vulnerability (CWE-862) in Juniper Networks Junos OS and Junos OS Evolved involves missing authorization checks in the CLI command 'show mgd'. A local user with low privileges can leverage this to access sensitive information that should be restricted. The issue affects all versions before specific releases across multiple Junos OS and Junos OS Evolved versions, including 22.4R3-S8, 23.2R2-S6, 23.4R2-S6, 24.2R2-S4, 24.4R2-S1, and 25.2R1-S2/25.2R2 for Junos OS, and corresponding versions for Junos OS Evolved. The CVSS 3.1 vector indicates local attack vector, low complexity, low privileges required, no user interaction, unchanged scope, and high confidentiality impact with no integrity or availability impact.
Potential Impact
A local user with low privileges can read sensitive information by exploiting missing authorization in the CLI. The confidentiality of sensitive data is compromised, but there is no impact on integrity or availability. This could lead to unauthorized disclosure of information within affected Junos OS and Junos OS Evolved devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only and monitor for unauthorized CLI usage. Avoid granting unnecessary CLI access to low-privilege users. Follow Juniper Networks advisories for updates on patches or temporary mitigations.
