1. EXECUTIVE SUMMARY
- CVSS v3 9.8
- ATTENTION: Exploitable remotely/low attack complexity
- Vendor: Dataprobe
- Equipment: iBoot-PDU FW
- Vulnerabilities: OS Command Injection, Path Traversal, Exposure of Sensitive Information to an Unauthorized Actor, Improper Access Control, Improper Authorization, Incorrect Authorization, SSRF, Stack-Based Buffer Overflow, Use of Weak Credentials, Plaintext Storage of a Password, Authentication Bypass Using an Alternate Path or Channel
2. UPDATE OR REPOSTED INFORMATION
This updated advisory is a follow-up to the original advisory titled ICSA-22-263-03 Dataprobe iBoot-PDU that was published September 20, 2022, on the ICS webpage on cisa.gov/ICS.
3. RISK EVALUATION
Successful exploitation of these vulnerabilities could lead to unauthenticated remote code execution on the Dataprobe iBoot-PDU device.
4. TECHNICAL DETAILS
4.1 AFFECTED PRODUCTS
The following versions of Dataprobe iBoot-PDU, a power distribution unit, are affected:
- Dataprobe iBoot-PDU FW: All Versions prior to 1.42.06162022
4.2 VULNERABILITY OVERVIEW
4.2.1 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN AN OS COMMAND (‘OS COMMAND INJECTION’) CWE-78
A specific function does not sanitize the input provided by the user, which may expose the affected an OS command injection vulnerability.
The device’s existing firmware allows unauthenticated users to access an old PHP page vulnerable to directory traversal, which may allow a user to write a file to the webroot directory.
The affected product exposes sensitive data concerning the device.
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.
Certain PHP pages only validate when a valid connection is established with the database. However, these PHP pages do not verify the validity of a user. Attackers could leverage this lack of verification to read the state of outlets.
Unauthenticated users could open PHP index pages without authentication and download the history file from the device; the history file includes the latest actions completed by specific users.
A specially crafted PHP script could use parameters from a HTTP request to create a URL capable of changing the host parameter. The changed host parameter in the HTTP could point to another host that will send a request to the host or IP specified in the changed host parameter.

The affected product is vulnerable to a stack-based buffer overflow, which could lead to a denial-of-service condition or remote code execution.
The affected product exposes multiple sensitive data fields of the affected product. An attacker can use the SNMP command to get a device MAC address and login as the administrator.
The iBoot device’s basic discovery protocol assists in initial device configuration. The discovery protocol shows basic information about devices on the network and allows users to perform configuration changes.
A proprietary protocol for iBoot devices is used for control and keepalive commands. The function compares the username and password and also contains the configuration data for the user specified. If the user does not exist, then it sends a value for username and password, which allows successful authentication for a connection.
The DataProbe cloud usernames and passwords are stored in plain text in a specific file. Any user able to read this specific file from the device could compromise other devices connected to the user’s cloud.

Uri Katz of Claroty Research reported these vulnerabilities to Dataprobe and CISA.
Dataprobe has released the following version update to mitigate these vulnerabilities:
——— Begin Update A Part 2 of 2 ———
- iBoot-PDU FW: Version 1.43.03312023
Instructions to upgrade can be found on Dataprobe’s website.

Dataprobe also recommends users to disable the SNMP if it is not in use.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls and isolate them from business networks.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
