iBoot PDU: Improper Neutralization of Special Elements used in an OS Command

Published Updated By the CyberSecBulletin desk

CVE-2023-3260 is a high-severity improper neutralization of special elements used in an OS command vulnerability in iBoot PDU from Dataprobe, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version <= 1.43.03312023 as the first without the flaw, so updating iBoot PDU to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.26% chance of exploitation within 30 days, higher than 70% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update iBoot PDU to <= 1.43.03312023 or a later version.
  2. Update Powerpanel Server to 2.6.9 or a later version.
  3. Update Iboot-pdu4a-c10 Firmware to 1.44.0804202 or a later version.
  4. Read the advisory on trellix.com for workarounds and exact fixed builds.

Official description

The Dataprobe iBoot PDU running firmware version 1.43.03312023 or earlier is vulnerable to command injection via the `user-name` URL parameter. An authenticated malicious agent can exploit this vulnerability to execute arbitrary command on the underlying Linux operating system.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
