What to do

  1. Update Iboot-pdu4a-c10 Firmware to 1.44.0804202 or a later version.
  2. Update Iboot-pdu4a-c20 Firmware to 1.44.0804202 or a later version.
  3. Update Iboot-pdu4a-n15 Firmware to 1.44.0804202 or a later version.
  4. Read the advisory on trellix.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The 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.

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How developers prevent this class of flaw

  • Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
