CVE-2022-0902: ABB Flow Computer and Remote Controllers Path Traversal Vulnerability in Totalflow TCP protocol can lead to root access

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in flow computer and remote controller products of ABB ( RMC-100 (Standard), RMC-100-LITE, XIO, XFCG5 , XRCG5 , uFLOG5 , UDC) allows an attacker who successfully exploited this vulnerability could insert and run arbitrary code in an affected system node.

Security readout for executives and security teams

Plain-English summary

This vulnerability affects ABB industrial flow computers and remote controllers used in operational environments. A remote, unauthenticated attacker could potentially abuse the Totalflow TCP protocol to escape intended file paths, inject commands, and run arbitrary code on an affected node, reportedly leading to root-level access.

Executive priority

Treat this as a high-priority OT exposure issue. Prioritize internet-facing or broadly reachable ABB flow-control assets, because compromise could affect sensitive industrial operations and device integrity.

Technical view

CVE-2022-0902 combines path traversal and command injection weaknesses in ABB Totalflow TCP protocol handling. The CVSS v3.1 score is 8.1, with network attack vector, no privileges or user interaction, high complexity, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is most likely where ABB RMC-100, RMC-100-LITE, XIO, XFCG5, XRCG5, uFLOG5, or UDC systems are reachable over networks that allow Totalflow TCP access. The bundle does not provide affected firmware versions.

Exploitation context

The source bundle does not show CISA KEV listing or cited active exploitation. The risk remains serious because successful exploitation can run arbitrary code on industrial control equipment, but the CVSS vector rates attack complexity as high.

Researcher notes

The bundle identifies CWE-22 and CWE-77 in the Totalflow TCP protocol and says exploitation may provide arbitrary code execution on affected nodes. Version granularity, patch identifiers, and exploit telemetry are not included, so validation depends on ABB advisory review.

Mitigation direction

  • Review ABB advisory 9AKK108467A0927 for affected versions and vendor fixes.
  • Restrict Totalflow TCP access to trusted management hosts only.
  • Place affected devices behind OT firewalls and segmentation controls.
  • Remove direct internet exposure for listed ABB devices.
  • Monitor vendor guidance if patch details are unavailable internally.

Validation and detection

  • Inventory listed ABB products across OT and remote sites.
  • Identify firmware and configuration status for each affected product.
  • Confirm whether Totalflow TCP is reachable from untrusted networks.
  • Review firewall rules for least-privilege access paths.
  • Check ABB advisory details before declaring systems remediated.
