CVE-2020-29061
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 · uneditedAn issue was discovered on CDATA 72408A, 9008A, 9016A, 92408A, 92416A, 9288, 97016, 97024P, 97028P, 97042P, 97084P, 97168P, FD1002S, FD1104, FD1104B, FD1104S, FD1104SN, FD1108S, FD1204S-R2, FD1204SN, FD1204SN-R2, FD1208S-R2, FD1216S-R1, FD1608GS, FD1608SN, FD1616GS, FD1616SN, and FD8000 devices. There is a default root126 password for the root account.
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 analysisA password or key is baked into the source or binary, so anyone who obtains the code obtains the credential. These are trivially found once the software is distributed. Remediation means removing the secret, rotating it, and loading credentials from secured configuration at runtime.

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.
dbcve · scoped- Identify the exact CDATA model and firmware version (e.g., 72408A, 9008A, etc.) from the device web interface or CLI.
- Log into the device administrative interface using the current credentials.
- Navigate to the user management or root account settings.
- Change the default password 'root126' to a strong, unique password (minimum 12 characters, mixed case, numbers, special characters).
- If the device allows separate admin accounts, create a non‑root admin account and disable root login over SSH/Telnet if possible.
- Save the configuration and reboot the device to ensure the new password takes effect.
- Restrict management access by applying ACLs or VPN so only trusted IP addresses can reach the device web/CLI.
- Periodically audit the device for any unauthorized accounts or unexpected configuration changes.
Generated from the published advisory — verify against the referenced sources before acting.
There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.
We develop and verify an original fix where the vendor hasn’t, from $3,550. Deployed to your staging first — never straight to production.
