Technical Details for CVE-2024-47575

Vulnerability Analysis

This vulnerability arises due to missing authentication in critical functions. This flaw allows an attacker to send specially crafted requests to execute arbitrary commands in the context of the application, potentially taking control of the affected system.

Root Cause

The vulnerability is caused by the absence of required authentication checks in critical functionalities within the FortiManager system.

Attack Vector

The attack is carried out remotely over the network, exploiting the lack of authentication in the application.

# Example exploitation code (sanitized)
import requests

url = "http://target-system/vulnerable-endpoint"
headers = {
    'Content-Type': 'application/json'
}
payload = {
    "command": "malicious_payload"
}

response = requests.post(url, headers=headers, json=payload)
print(response.status_code)

Detection Methods for CVE-2024-47575

Indicators of Compromise

• Unexpected outgoing connections from FortiManager
• Unusual spike in command usage logs
• Presence of unknown processes or files

Detection Strategies

Organizations should deploy network monitoring tools to detect unauthorized access attempts and inspect HTTP requests to identify malicious payloads.

Monitoring Recommendations

Regularly audit access logs for unusual activity, and use Intrusion Detection Systems (IDS) with signatures tailored for FortiManager traffic anomalies.
