Published Updated By the CyberSecBulletin desk

CVE-2022-3186 is a high-severity improper access control vulnerability in iBoot-PDU FW from Dataprobe, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected iBoot-PDU FW versions: 1.42.06162022 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.61% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Iboot-pdu4-n20 Firmware to 1.42.06162022 or a later version.
  2. Update Iboot-pdu4sa-n15 Firmware to 1.42.06162022 or a later version.
  3. Update Iboot-pdu4a-n15 Firmware to 1.42.06162022 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Dataprobe iBoot-PDU FW versions prior to 1.42.06162022 contain a vulnerability where the affected product allows an attacker to access the device’s main management page from the cloud. This feature enables users to remotely connect devices, however, the current implementation permits users to access other device's information.

The underlying weakness: Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
