How the Exploit Works
The exploit takes advantage of the AI command injection vulnerability in M365 Copilot. This flaw allows an attacker to inject malicious AI commands into the system, bypassing normal authentication and authorization processes. Due to improper input validation, the system executes these commands, potentially leading to unauthorized access, data leakage, or even system compromise.
Conceptual Example Code
Here’s a
conceptual
example of how an attacker might exploit this vulnerability using a crafted HTTP request:
POST /ai/command/inject HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"ai_command": "extract_all_user_data();"
}In this example, the `ai_command` is a malicious payload that instructs the system to carry out an unauthorized action – in this case, extracting all user data.
Mitigation Guidance
The most effective way to mitigate this vulnerability is to apply the vendor-provided patch as soon as possible. In situations where immediate patching isn’t feasible, implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary measure to prevent exploitation of this vulnerability. However, these mitigation strategies should be seen as stopgap solutions until the patch can be applied, which ultimately rectifies the root cause of the vulnerability.
