CVE-2022-47311
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 · uneditedA proprietary protocol for iBoot devices is used for control and keepalive commands. The function compares the username and password; it also contains the configuration data for the user specified. If the user does not exist, then it sends a value for username and password, which allows successful authentication for a connection.
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.

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 · scoped1.42.06162022
Firmware version 1.42.06162022 or later
- Obtain the firmware update version 1.42.06162022 or later from Dataprobe (the vendor of iBoot PDU devices)
- Consult the vendor's official firmware upgrade documentation for your specific iBoot PDU model (Pdu4 N20, Pdu4sa N15, Pdu4a N15, Pdu4sa N20, Pdu4a N20, Pdu8sa N15, Pdu8a N15, or Pdu8sa 2n15)
- Follow the vendor's standard firmware update procedure, which typically involves accessing the device management interface and uploading the new firmware file
- After upgrading, verify that the device is running firmware version 1.42.06162022 or later
- Confirm that the authentication bypass vulnerability is remediated by testing that non-existent users can no longer authenticate successfully
