CVE-2023-0344
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 · uneditedAkuvox E11 appears to be using a custom version of dropbear SSH server. This server allows an insecure option that by default is not in the official dropbear SSH server.
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 device runs a custom-modified version of the Dropbear SSH server that has an insecure configuration option enabled by default. This insecure setting (likely related to authentication, root access, or weak crypto) allows remote attackers to potentially bypass authentication or leverage weakened security controls, resulting in CVSS 7.5 HIGH severity.

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.
-
Confirm device is Akuvox E11Identify the target device model. For Akuvox E11, this is an IP door phone/intercom device. Check device documentation, web interface, or system information.Affected if The target device is an Akuvox E11 model
-
Verify SSH service is runningCheck if the Dropbear SSH server is active on the device. Common methods: scan for open port 22, check running processes for dropbear, or query the device's service status if administrative access is available.Affected if SSH service (Dropbear) is enabled and accessible on the device
-
Locate Dropbear SSH configurationFind the Dropbear SSH configuration file. Common paths may include /etc/dropbear/, /etc/ssh/, or device-specific config directories. Inspect the configuration for options related to authentication, root access, or cryptographic settings.Affected if A configuration option related to authentication, root access, or weak crypto is present and enabled
If the device is an Akuvox E11 with SSH service enabled, it is affected regardless of firmware version since all versions contain the insecure Dropbear configuration.

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 dataContact Akuvox for a firmware update that removes or disables the insecure SSH option. If no update is available, disable SSH access externally via firewall rules or disable the SSH service entirely if not required.
