MITRE ATT&CK
2 techniques across 2 tactics: Persistence, Credential Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires network reachability to the OpenEye Apex NVR management/password-reset interface on firmware 3.2.9.376 (design present since at least 2.2.3.4). No authentication is needed because the attacker supplies the undocumented, shared hardcoded recovery credential (CWE-798), which cannot be changed, disabled, or rotated. The critical limiting factor is impact scope: the recovery account only reaches the password-reset workflow and does NOT grant normal administrator access - full administrator takeover requires chaining separate, additional vulnerabilities not covered by this CVE. Mitigation is upgrading to firmware 3.5.4. |
| Impact | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N = 6.5, MEDIUM) is internally consistent with the description: a network-reachable, low-complexity, unauthenticated flaw with only LOW confidentiality and LOW integrity impact and no availability impact. The comparatively modest score is well-justified because the vendor and Securifera both stress that the hardcoded recovery account 'does not provide normal administrator access' - it only lets an attacker authenticate to the password-reset workflow, and additional (separate) vulnerabilities are required to reach full administrator takeover. This is therefore best understood as a chainable foothold rather than a standalone critical breach. No EPSS score, CISA KEV listing, or public exploit code is present in the provided data, so this is no public exploit identified at time of analysis; there is no evidence of active exploitation. The primary risk driver is that the credential is hardcoded, shared across the fleet, and cannot be changed, disabled, or rotated, and has been present since at least firmware 2.2.3.4 - meaning every unpatched Apex NVR shares the same permanent backdoor-class weakness. Real priority is moderate: high exposure and trivial reachability, but capped real-world impact absent the follow-on vulnerabilities needed for takeover. Note the tension between the CWE-798 (hardcoded credentials) classification and the vendor 'Authentication Bypass' tag - the mechanism is use of undocumented built-in credentials, not a logic bypass; treat the CWE as authoritative. |
| Exploit ScenarioDerived | An attacker who can reach an Apex NVR's management interface over the network uses the undocumented, hardcoded recovery credential - identical across all devices on the affected firmware - to authenticate to the password-reset workflow without any prior access. From that foothold they leverage the reset workflow and additional vulnerabilities to escalate toward administrative control of the video-surveillance recorder. No public exploit is identified at time of analysis, but the credential's static, unchangeable nature makes reliable reuse trivial once known. |

Unauthenticated remote attackers can authenticate to the password-reset workflow of OpenEye Apex Network Video Recorder (NVR) firmware 3.2.9.376 using a hardcoded, shared recovery credential (CWE-798) that cannot be changed, disabled, or rotated. This flaw has been present since at least firmware 2.2.3.4 and grants only access to the password-reset workflow, not normal administrator privileges; full admin takeover requires chaining additional vulnerabilities. The CVSS 3.1 score is 6.5 (MEDIUM) with LOW confidentiality and integrity impact, and no public exploit code has been identified at time of analysis. Upgrade to firmware 3.5.4 to remediate.
RemediationAI
Vendor-released patch: upgrade to OpenEye Apex NVR firmware version 3.5.4 to remove the hardcoded recovery account and fully remediate the vulnerability. Consult the vendor advisory at https://portal.openeye.net/updates/issue-alerts/1058 for update instructions. Because the affected recovery account cannot be disabled or rotated, no complete workaround exists short of upgrading. As a compensating control, restrict network access to the NVR management and password-reset interface using firewall rules or network segmentation, allowing only trusted administrative hosts; this reduces remote exposure but prevents legitimate remote management and password-reset operations from untrusted networks. Monitor authentication logs for attempts to access the password-reset workflow using the known recovery account to detect exploitation attempts, though this does not prevent the attack. The Securifera advisory at https://www.securifera.com/advisories/ may provide additional technical details.

Technical ContextAI · show details
The vulnerability is an instance of CWE-798 (Use of Hard-coded Credentials) in OpenEye Apex Network Video Recorder (NVR) firmware. The firmware contains an undocumented recovery account that uses a shared, static credential which cannot be changed, disabled, or rotated by administrators. The account is reachable over the network and allows an attacker to authenticate to the password-reset workflow without any prior authentication, as reflected by the CVSS vector AV:N/AC:L/PR:N/UI:N (network-reachable, low complexity, no privileges required, no user interaction). The impact is limited: the recovery account does not provide normal administrator access, so an attacker can only interact with the password-reset functionality. Achieving full administrator takeover would require additional vulnerabilities not covered by this CVE. The CPE cpe:2.3:a:openeye:apex_network_video_recorder_(nvr):*:*:*:*:*:*:*:* indicates the product family is affected broadly, with the specific reported vulnerable version being 3.2.9.376 and the design flaw present since at least 2.2.3.4.

DescriptionCVE.org
OpenEye Apex Network Video Recorder (NVR) firmware 3.2.9.376 contains a hardcoded, undocumented recovery account with a shared credential that cannot be changed, disabled, or rotated. An unauthenticated remote attacker can use the account to authenticate to the password-reset workflow. The account does not provide normal administrator access; additional vulnerabilities are required to obtain an administrator takeover. The underlying design has been present since at least firmware 2.2.3.4.
Upgrade to version 3.5.4.
