How the Exploit Works
The vulnerability lies in the set_password function in application/controllers/home.php of jerryhanjj ERP 1.0. An attacker could exploit this weakness by injecting malicious SQL code. Since the software does not adequately sanitize user-supplied input, the attacker’s injected code could be executed in the database, potentially granting unauthorized access or disclosing sensitive information.
Conceptual Example Code
Here’s a hypothetical example of how an attacker might exploit this vulnerability:
POST /set_password HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin&password=' OR '1'='1'; DROP TABLE users; --In the above example, the attacker attempts to change the password of the ‘admin’ user. The attacker uses SQL Injection to manipulate the statement into always being true (OR ‘1’=’1′) and subsequently adding an additional SQL command to drop the “users” table, causing data loss or system compromise.
Mitigation and Prevention
The most effective solution to this vulnerability is to apply the vendor-supplied patch as soon as possible. The patch aims to rectify the issue by correctly sanitizing user input to prevent SQL Injection attacks. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block potential SQL Injection attempts. However, these measures should be seen as a stopgap until the patch can be applied, as they may not block all possible attack vectors.
