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

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could lead to unauthenticated remote code execution on the Dataprobe iBoot-PDU device. 

3. TECHNICAL DETAILS

3.1 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

3.2 VULNERABILITY OVERVIEW

3.2.1    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. 

CVE-2022-3183 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

3.2.2    IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY ('PATH TRAVERSAL') CWE-22

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.

CVE-2022-3184 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

3.2.3    EXPOSURE OF SENSITIVE INFORMATION TO AN UNAUTHORIZED ACTOR CWE-200

The affected product exposes sensitive data concerning the device.

CVE-2022-3185 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

3.2.4    IMPROPER ACCESS CONTROL CWE-284

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.

CVE-2022-3186 has been assigned to this vulnerability. A CVSS v3 base score of 8.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).

3.2.5    IMPROPER AUTHORIZATION CWE-285

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. 

CVE-2022-3187 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

3.2.6    INCORRECT AUTHORIZATION CWE-863

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.

CVE-2022-3188 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

3.2.7    SERVER-SIDE REQUEST FORGERY (SSRF) CWE-918

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.

CVE-2022-3189 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

3.3 BACKGROUND

  • CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing
  • COUNTRIES/AREAS DEPLOYED: Multiple
  • COMPANY HEADQUARTERS LOCATION: United States

3.4 RESEARCHER

Uri Katz of Claroty Research reported these vulnerabilities to Dataprobe and CISA.

4. MITIGATIONS

Dataprobe has released the following version update to mitigate these vulnerabilities:

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 this vulnerability 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.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploits specifically target these vulnerabilities.
