How the Exploit Works
The exploit works by creating a custom file that, when opened within the Arena Simulation software, forces the application to read and write past the end of its allocated memory space. This overreach of memory boundaries can lead to buffer overflow conditions, which can be leveraged by a threat actor to execute arbitrary code or disclose sensitive information.
Conceptual Example Code
The following is a conceptual example of the crafted malicious payload that could be used to exploit this vulnerability. It’s important to note that this is a hypothetical example and is provided for understanding purposes only.
POST /arena_simulation/open_file HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "file_path": "/path/to/malicious/file" }In this example, `file_path` would be replaced with the path to a custom file that triggers the memory abuse issue when opened in the Arena Simulation software.
Remediation
Rockwell Automation is expected to release a patch that addresses this vulnerability. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These systems can be configured to detect and block attempts to exploit this vulnerability, helping to protect systems until the official patch is released and applied.
