How the Exploit Works
An attacker can exploit this vulnerability by sending specially crafted SQL commands to the affected application. Due to the improper neutralization of special elements used in an SQL command by the software, an attacker can manipulate SQL queries, leading to unauthorized access, data manipulation, or data leakage.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited. This example uses an HTTP request with a malicious SQL command in a data field:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin' OR '1'='1'; --&password=passIn the above example, the attacker is injecting a SQL command (‘OR ‘1’=’1′; –) into the “username” field in an attempt to bypass authentication.
Mitigation
To mitigate this vulnerability, users are advised to apply the latest patches provided by the vendor. If a patch is not yet available or cannot be applied immediately, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation method, potentially preventing the exploitation of this vulnerability.
