CVE-2023-3259
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. By manipulating the IP address field in the "iBootPduSiteAuth" cookie, a malicious agent can direct the device to connect to a rouge database.Successful exploitation allows the malicious agent to take actions with administrator privileges including, but not limited to, manipulating power levels, modifying user accounts, and exporting confidential user information
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 contains an authentication bypass vulnerability. Attackers can manipulate the IP address field in the iBootPduSiteAuth cookie to redirect the device's authentication to a rogue database controlled by the attacker, bypassing proper authentication controls.

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.
-
Verify firmware versionAccess the device web interface or use SNMP to retrieve the current firmware version. Look for a version display in the device status or system information page.Affected if The installed firmware version is 1.43.03312023 or earlier, or any version prior to 1.44.0804202.
-
Confirm device modelIdentify the exact iBoot PDU model (e.g., PDU4a C10, PDU4a C20, PDU4a N15, PDU4a N20, PDU4 C20, PDU4 N20, PDU4sa C10, PDU4sa C20) from the device label or web interface.Affected if The device model matches one of the affected product lines and the firmware version is below 1.44.0804202.
-
Assess network exposureDetermine whether the PDU web management interface is accessible from untrusted networks. Review firewall rules and access control lists restricting access to the device HTTPS/HTTP ports.Affected if The management interface is exposed to the internet or untrusted internal networks without proper access controls.
-
Inspect authentication cookieUsing a browser or intercepting proxy, examine the iBootPduSiteAuth cookie sent during authentication sessions. Look for any IP address fields within the cookie value that point to unexpected or external domains.Affected if The cookie contains an IP address or hostname that does not match the legitimate device or authorized internal authentication database.
A user is affected if their Dataprobe iBoot PDU device runs firmware version 1.43.03312023 or earlier (below 1.44.0804202) and has its web management interface network-accessible.

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
Apply the vendor firmware update to a version newer than 1.43.03312023 once released. Restrict network access to the PDU management interface and monitor for suspicious cookie modifications.
Firmware version 1.44.0804202 or later
- Check current firmware version on the iBoot PDU device through the web interface or CLI
- Download firmware version 1.44.0804202 or later from Dataprobe's official support website
- Review the firmware upgrade instructions provided by Dataprobe before proceeding
- Upload and apply the firmware update through the device's web interface or appropriate management method
- After rebooting, verify the firmware version has been successfully updated to 1.44.0804202 or later
- As a security precaution, review and reset all user credentials and administrator accounts since the vulnerability allowed authentication bypass
- Verify that the 'iBootPduSiteAuth' cookie behavior is now properly validating against the expected database
