CVE-2026-33390: CWE-266 Incorrect privilege assignment in Nozomi Networks Guardian
An Incorrect Privilege Assignment vulnerability was discovered in the synchronization functionality due to Arc sensors receiving CLI permissions. An authenticated user with limited privileges can push administrative CLI commands through the sync, altering the device configuration, and/or affecting its availability.
AI Analysis
Technical Summary
This vulnerability involves improper privilege assignment in the synchronization mechanism of Nozomi Networks Guardian. Specifically, Arc sensors receive CLI permissions that they should not have, enabling an authenticated user with limited privileges to execute administrative CLI commands through synchronization. This can lead to unauthorized configuration changes or availability issues on the device. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no user interaction, and high impact on integrity and availability.
Potential Impact
An attacker with limited authenticated privileges can leverage this flaw to execute administrative CLI commands remotely via synchronization. This could result in unauthorized configuration changes or disruption of device availability, potentially impacting the security posture and operational continuity of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation is provided, users should monitor Nozomi Networks advisories for updates. Until a fix is available, restrict access to authenticated users and limit synchronization operations to trusted environments where possible.
