CVE-2023-0353
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 uses a weak encryption algorithm for stored passwords and uses a hard-coded password for decryption which could allow the encrypted passwords to be decrypted from the configuration file.
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 confidenceAkuvox E11 device uses a weak encryption algorithm to store passwords in its configuration file, combined with a hard-coded decryption password embedded in the firmware. An attacker who obtains the configuration file can decrypt all stored passwords using this known key.

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 modelCheck the device label, web interface, or system information to confirm the model is Akuvox E11Affected if Device model is Akuvox E11
-
Locate configuration fileAccess the device firmware or backup configuration file - typically found at /mnt/config or via firmware extraction toolsAffected if Configuration file exists and contains encrypted password fields
-
Check for weak encryption in configExamine the configuration file for Base64-encoded or simply obfuscated password fields rather than proper cryptographic hashingAffected if Passwords appear encoded (Base64) or weakly obfuscated rather than cryptographically hashed
-
Verify hardcoded key presence in firmwareExtract firmware (using binwalk or similar) and search for hardcoded strings/passwords used for decryption (look for patterns like 'decrypt', 'key', or known weak key strings)Affected if Firmware contains hardcoded decryption keys or weak encryption routines
-
Test password decryptabilityAttempt to decrypt password fields from config using common weak algorithms (Base64, simple XOR, or known default keys)Affected if Passwords can be decrypted using known weak methods
If the device is an Akuvox E11 with a configuration file containing weakly encrypted passwords, the environment is affected by CVE-2023-0353 since all firmware versions contain the hardcoded decryption key.

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 dataIsolate affected devices on restricted network segments, enforce strong unique passwords for all accounts, and contact Akuvox for a firmware patch that addresses the weak encryption and removes hard-coded credentials.
