How the Exploit Works

The vulnerability lies within the /setupA.cfg file of the web-based management interface. Attackers who have access to the local network can manipulate this file, leading to a missing authentication. This situation can allow the attacker to execute unauthorized activities, potentially leading to system compromise or data leakage.

Conceptual Example Code

The following conceptual example illustrates how the vulnerability might be exploited using a malicious shell command:

$ curl -X POST -d "@payload.json" http://target_comet_system/setupA.cfg

Here, “payload.json” is a crafted JSON file that contains the malicious payload which manipulates /setupA.cfg for bypassing authentication.
