CVE-2026-92930: OpenEye Apex NVR Auth Bypass Vulnerability

CVE-2026-92930 Overview

CVE-2026-92930 is a cryptographic design weakness in OpenEye Apex Network Video Recorder (NVR) firmware version 3.2.9.376. The administrator password-reset workflow generates unlock codes without a per-device secret or server-side cryptographic material. An attacker with physical console access to the privileged password-reset interface can forge a valid unlock code offline. The forged code resets the administrator password and grants full control of the NVR. The flawed design has existed since at least firmware 2.2.3.4, exposing a large installed base to the same weakness. The issue is tracked under CWE-330: Use of Insufficiently Random Values.

Critical Impact
A physically present attacker can compute a valid administrator password-reset code offline and take full control of affected OpenEye Apex NVR devices.

Affected Products

OpenEye Apex NVR firmware 3.2.9.376
OpenEye Apex NVR firmware versions since 2.2.3.4

Technical Details for CVE-2026-92930

Vulnerability Analysis

The OpenEye Apex NVR firmware implements an administrator password-reset workflow protected by an unlock code. The unlock code scheme relies only on values available to any operator sitting at the local console. No per-device secret, no server-issued nonce, and no cryptographic material held outside the device participate in the code generation or validation logic.

Because validation depends entirely on client-side or device-visible inputs, an attacker who understands the algorithm can reproduce it offline. The attacker does not need vendor infrastructure, network connectivity, or prior authentication beyond access to the password-reset workflow. The algorithm has remained unchanged across many firmware releases, so a single reverse-engineering effort applies to devices in the field since firmware 2.2.3.4.

Successful exploitation resets the administrator credential and yields full control of the video management system. Attackers can view recorded footage, delete evidence, disable cameras, alter retention policies, and pivot into connected surveillance infrastructure.

Root Cause

The root cause is a violation of CWE-330: Use of Insufficiently Random Values. The unlock-code generator lacks entropy that is not knowable to the attacker. Any secure password-reset design must bind the unlock code to a value held by the vendor or provisioned uniquely per device. The Apex firmware omits both, reducing the reset mechanism to security-by-obscurity of the algorithm itself.

Attack Vector

Exploitation requires physical access to the NVR console and access to the privileged password-reset workflow. The attacker triggers the reset flow, reads the device-provided challenge material, computes the corresponding unlock code offline using the reverse-engineered algorithm, and submits it to reset the administrator password. No network exposure or valid credentials are required beyond reaching the reset prompt.

A sanitized code example is not published because no proof-of-concept has been released and no verified exploit artifacts are available. Refer to the OpenEye Issue Alert #1060 and the Securifera Security Advisory for vendor and researcher details.

Detection Methods for CVE-2026-92930

Indicators of Compromise

Unexpected administrator password changes on Apex NVR devices without a corresponding change-management ticket.
Console-initiated password-reset events logged outside of scheduled maintenance windows.
Sudden loss of access to the NVR by legitimate administrators followed by new administrator logins from local sessions.
Modifications to camera retention, deletion of recorded footage, or disabled video streams shortly after a reset event.

Detection Strategies

Enable and forward NVR audit logs to a centralized log store and alert on any password-reset workflow invocation.
Correlate physical access records with authentication events on the NVR to identify unauthorized console sessions.
Baseline administrator account activity and flag configuration changes performed within minutes of a reset event.

Monitoring Recommendations

Monitor privileged account changes on all Apex NVR devices through a centralized SIEM.
Alert on new local logons following any reset workflow event.
Track firmware version inventory to identify devices still running 3.2.9.376 or earlier.

How to Mitigate CVE-2026-92930

Immediate Actions Required

Upgrade all OpenEye Apex NVR devices to firmware version 3.5.4 or later.
Restrict physical access to NVR consoles using locked equipment enclosures and controlled facility entry.
Audit administrator accounts and rotate credentials on any device suspected of unauthorized console access.
Enable console-session logging and forward events to a monitored log repository.

Patch Information

OpenEye addresses the flaw in Apex NVR firmware 3.5.4. The vendor documents the fix in OpenEye Issue Alert #1060. Administrators should schedule the upgrade across all Apex NVR appliances and verify firmware version after deployment.

Workarounds

Place NVR appliances in locked racks or dedicated equipment rooms with access logging.
Disable or physically block local console interfaces where operationally feasible until the patch is applied.
Limit personnel authorized to perform password-reset procedures and require dual control for reset operations.
Deploy tamper-evident seals on device chassis to detect unauthorized physical interaction.

bash

# Verify installed firmware version on OpenEye Apex NVR
# and confirm the device is running the patched release 3.5.4 or later
# Example command executed from the NVR local console
openeye-cli system info --field firmware_version

# Expected output for a patched device:
# firmware_version: 3.5.4
