Overview
In the constantly evolving landscape of cybersecurity, one of the persistent threats is SQL Injection. This blog post discusses a recent discovery of a time-based blind SQL injection vulnerability, CVE-2025-51672, in the PHPGurukul Dairy Farm Shop Management System version 1.3. The identification and mitigation of such vulnerabilities are critical to maintaining robust cybersecurity, as they can potentially lead to unauthorized system access, data leakage, and even system compromise.

How the Exploit Works
The vulnerability resides in the manage-companies.php file of the PHPGurukul Dairy Farm Shop Management System. The software does not properly sanitize user-supplied input in the companyname parameter in a POST request. An attacker can inject arbitrary SQL code into the POST request, which the server then processes as a valid SQL command. This allows the attacker to manipulate the database, potentially leading to unauthorized access, data leakage, or system compromise.
Conceptual Example Code
Here is a conceptual example of a malicious HTTP POST request exploiting this vulnerability:
POST /manage-companies.php HTTP/1.1
Host: targetsite.com
Content-Type: application/x-www-form-urlencoded
companyname=' UNION SELECT username, password FROM users WHERE 'x'='xIn this example, the attacker uses the UNION SQL command to combine the results of their injected SELECT command with the results of the original SQL query. The WHERE ‘x’=’x condition always evaluates to true, causing the injected SELECT command to return all usernames and passwords from the users table.
Mitigation Guidance
The recommended mitigation for this vulnerability is to apply the vendor-supplied patch as soon as it is available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and block attempts to exploit this vulnerability. Furthermore, it is always a good practice to sanitize all user-supplied inputs to prevent SQL injection attacks.
