CVE-2023-3263
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 Dataprobe iBoot PDU running firmware version 1.43.03312023 or earlier is vulnerable to authentication bypass in the REST API due to the mishandling of special characters when parsing credentials.Successful exploitation allows the malicious agent to obtain a valid authorization token and read information relating to the state of the relays and power distribution.
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 confidenceThe Dataprobe iBoot PDU firmware versions 1.43.03312023 and earlier contain an authentication bypass vulnerability in the REST API. The issue stems from improper handling of special characters during credential parsing, allowing attackers to craft requests that bypass authentication and obtain valid authorization tokens. Once authenticated, attackers can read sensitive information about relay states and power distribution configuration.

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 model and firmware versionAccess the iBoot PDU web interface or use the device's CLI to retrieve the firmware version information. This is typically found in the device status, system information, or about section.Affected if The firmware version is 1.43.03312023 or earlier, or the version is less than 1.44.0804202.
-
Confirm REST API availabilityVerify that the REST API endpoint is accessible on the device. The API is typically available at a path such as /api or /rest on the device's management interface.Affected if The REST API is exposed and reachable on the network.
-
Review API access logs for anomaliesExamine the device's logs or any associated logging infrastructure for API requests that may indicate authentication bypass attempts or unusual authorization token usage.Affected if Logs show successful API authentication without proper credential submission or unauthorized token usage.
A user is affected if their Dataprobe iBoot PDU device is running firmware version 1.43.03312023 or earlier (less than 1.44.0804202) and has the REST API accessible.
Generated from the published advisory. Verify against your own 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.
dbcve · scoped1.44.0804202
Upgrade the iBoot PDU firmware to a version newer than 1.43.03312023. As a compensating control, implement network segmentation to restrict access to the PDU management interface and monitor for unauthorized API access attempts.
Firmware version 1.44.0804202 or later
- 1. Identify the specific iBoot PDU model (e.g., Pdu4a C10, Pdu4 C20, etc.) from the affected product list
- 2. Navigate to the Dataprobe support or download page to obtain firmware version 1.44.0804202 or later
- 3. Review the vendor's firmware upgrade instructions for your specific model
- 4. Backup current configuration if the device supports configuration export
- 5. Upload the new firmware file to the iBoot PDU device through the web interface or CLI as specified by vendor instructions
- 6. Wait for the firmware upload and installation to complete
- 7. Reboot the device if required by the firmware update process
- 8. Verify the firmware version has been updated to 1.44.0804202 or later
