Affected Products

Product | Affected Versions

RomanCode MapSVG | All versions

How the Exploit Works

This SQL Injection vulnerability is exploited when an attacker sends malicious SQL statements in an input field, tricking the application into executing unintended commands or accessing unauthorized data. As the application does not properly sanitize the input, these statements are integrated into the SQL query and executed by the database. This can provide the attacker with unauthorized access to sensitive data, or even allow them to manipulate or delete this data.

Conceptual Example Code

Here is a conceptual example of how the SQL Injection vulnerability might be exploited. This is a sample HTTP request with a malicious payload:
```
POST /api/maps HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "search": "'; DROP TABLE users; --" }
```
In the above example, the “search” parameter is injected with a malicious SQL statement `’; DROP TABLE users; –`. If the application does not properly sanitize this input, it will be interpreted as part of an SQL command, causing the “users” table to be dropped, resulting in data loss.

User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

SQL Server | All versions prior to patch

How the Exploit Works

The exploit works by manipulating the SQL queries executed by the SQL Server. An attacker with authorized access could insert or “inject” malicious SQL code into user input fields or through network protocols that interact with the database. If the input is not properly sanitized or parameterized, the server may execute the injected SQL command, allowing the attacker to manipulate the database or retrieve sensitive data. This can lead to unauthorized access, data leakage, or even system compromise.

Conceptual Example Code

Here’s a conceptual example demonstrating how SQL Injection might be carried out, using a simple HTTP request with a malicious payload:
```
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin&password=' OR '1'='1' --
```
In this example, the attacker is attempting to bypass the login mechanism by injecting malicious SQL code into the ‘password’ field. If the server is vulnerable and does not properly sanitize this input, the SQL Server might interpret the query as “Return true if the username is ‘admin’ OR ‘1’ equals ‘1’. Since ‘1’ always equals ‘1’, the query will return true, potentially allowing the attacker to login as the ‘admin’ user without knowing the actual password.

Mitigation Guidance

To mitigate this vulnerability, it is highly recommended to apply the vendor’s patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation method. Additionally, adopting good coding practices, such as input validation and parameterized queries, can significantly reduce the risk of SQL Injection attacks.
