Rockwell ControlLogix Exploitation

On July 20th, 2023, Rockwell Automation revealed a Path Traversal exploit in both their ThinManager and ThinServer software. This vulnerability (CVE-2023-2913) allows remote adversaries to perform directory traversal attacks with low attack complexity. The vulnerability is caused by an input validation error when processing directory traversal sequences and will allow a remote attacker to send specially designed HTTP requests to gain access to and read arbitrary files on the system. Attackers could potentially execute a path that contains manipulating variables.

Actions and/or Recommendations

  • Determine if CVE-2023-2913 impacts your current systems.
    • Ensure projects moving forward are managing this CVE.
  • Engage Mangan Cybersecurity for assistance with impacted systems.
  • Update to the corrected Rockwell software versions: 13.0.3 and 13.1.1 or later.
  • Develop a monitoring strategy to identify undesired access or activity on the OT/ICS Network.

Mangan Cybersecurity has well-established templates and techniques to assist with the above suggestions expediently and effectively.
