CVE-2023-0351
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 web server backend library allows command injection in the device phone-book contacts functionality. This could allow an attacker to upload files with executable command instructions.
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 · moderate confidenceThe Akuvox E11 VoIP door phone contains a command injection vulnerability in its web server backend library's phone-book contacts functionality. An attacker can exploit this to upload files containing executable command instructions, potentially achieving remote code execution on the device.

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 device modelAccess the device web interface or check device labeling/marketing materials to confirm the model is Akuvox E11Affected if Device model is Akuvox E11
-
Confirm web server is accessibleAttempt to access the device's web interface via HTTP/HTTPS on the expected management port (typically 80/443 or vendor-defined)Affected if Web interface responds and exposes the phone-book contacts functionality
-
Verify phone-book contacts feature existsNavigate to the phone-book or contacts management section within the web interface to confirm this feature is present and accessibleAffected if Phone-book contacts upload/management feature is available and enabled on the device
-
Check for unauthorized files or scriptsIf file system access is available, search for unexpected scripts or uploaded files in web-accessible directories (/www, /tmp, /var) that may indicate exploitationAffected if Unexpected files containing shell commands or suspicious scripts are found on the device
-
Review network exposureDetermine if the device web interface is accessible from untrusted networks (public IP, no VPN, no firewall restriction)Affected if Web interface is exposed to untrusted networks without IP restrictions
If the device is an Akuvox E11 with its web interface and phone-book contacts feature accessible, the environment is affected by this vulnerability.

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 the vendor-supplied firmware update for Akuvox E11 when available, or restrict network access to the device's web interface to trusted IPs until the patch can be deployed.
