How the Exploit Works
This vulnerability allows an attacker to inject malicious SQL commands into the application. This is achieved when the application fails to properly neutralize special elements used in SQL commands before they’re sent to a downstream component. This allows the attacker to manipulate the SQL query to gain unauthorized access, extract sensitive data, or even execute administrative operations on the database.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This example is a Post HTTP request that injects a SQL command into a parameter that is not properly sanitized.
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=administrator' OR '1'='1'; -- &password=guestIn this example, the SQL command ‘OR ‘1’=’1′ is injected into the username parameter. This command is always true, therefore it bypasses any authentication mechanism present and allows the attacker to log in as an administrator.
Mitigation Guidance
To mitigate this vulnerability, users of Bob Hostel should immediately apply the vendor’s patch. If the patch is not available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary measure to detect and block SQL Injection attacks. The application’s code should also be reviewed and updated to ensure proper sanitization of all input data.
