How the Exploit Works
The attacker takes advantage of the software’s inability to correctly neutralize special characters in SQL commands. This allows the attacker to manipulate SQL queries, potentially leading to unauthorized read or write access to the database. The attacker could then gain unauthorized access to sensitive data and even execute arbitrary commands on the host system.
Conceptual Example Code
The following is a conceptual example of how this vulnerability might be exploited:
POST /librodeReclamacionesyQuejas/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"user_input": "'; DROP TABLE users;--"
}In this example, the attacker sends a malicious payload containing an SQL injection. The payload, if processed by a vulnerable endpoint, would lead to the deletion of the ‘users’ table from the database.
Mitigation Guidance
It is recommended that users apply the vendor patch as soon as it becomes available. As a temporary mitigation, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and filter out SQL Injection attempts. Regularly updating and patching software, limiting access privileges, and input validation can also help prevent SQL Injection vulnerabilities.
