CVE-2023-0349
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Akuvox E11 libvoice library provides unauthenticated access to the camera capture for image and video. This could allow an attacker to view and record image and video from the camera.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Akuvox E11 device's libvoice library exposes camera capture functionality without requiring authentication, allowing remote attackers to view and record video/images from the device's camera without any credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Akuvox E11 devices on your networkLocate devices by checking device labels, management interface, or using network discovery tools to identify the model numberAffected if Device model is confirmed as Akuvox E11
-
Confirm firmware versionAccess the device management interface or use firmware retrieval commands to obtain the installed firmware versionAffected if Any firmware version is returned (all versions are affected)
-
Verify libvoice service availabilityCheck if the libvoice library service is running and accessible on the device, typically by scanning for open ports associated with the camera streaming functionalityAffected if libvoice service is detected and accessible on the network
-
Test camera authentication requirementAttempt to access camera capture endpoints (such as RTSP or HTTP interfaces used by libvoice) without providing credentials to verify if authentication is enforcedAffected if Camera feed or images can be accessed without any authentication credentials
-
Check network exposure of camera interfaceReview firewall rules and network segmentation to determine if the device camera ports are reachable from untrusted network segmentsAffected if Camera interface is accessible from networks outside of trusted management segments
If an Akuvox E11 device is present on your network with its libvoice camera service accessible, the device is affected since all firmware versions lack authentication on this service.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware updates when available; otherwise, isolate the device on a restricted network segment and implement firewall rules to limit exposure to trusted sources only.
