SQL Injection Vulnerability in itsourcecode Payroll Management System 1.0 (CVE-2026-5237)

itsourcecode Payroll Management System 1.0 is vulnerable to SQL injection, specifically within the /manage_user.php file. The vulnerability, identified as CVE-2026-5237, stems from improper sanitization of the ID parameter. A remote attacker can exploit this flaw to inject arbitrary SQL commands into the application’s database queries. Publicly available exploit code exists, increasing the risk of exploitation. This vulnerability allows attackers to potentially compromise the entire database.

Attack Chain

1. The attacker identifies an instance of itsourcecode Payroll Management System 1.0.
2. The attacker crafts a malicious HTTP request targeting the /manage_user.php file.
3. The attacker injects SQL code into the ID parameter within the crafted HTTP request.
4. The web server passes the tainted ID parameter to the vulnerable SQL query without proper sanitization.
5. The injected SQL code is executed against the database.
6. The attacker gains unauthorized access to sensitive data within the database, such as user credentials or payroll information.
7. The attacker can modify or delete data within the database.

Impact

Successful exploitation of this vulnerability can lead to the complete compromise of the itsourcecode Payroll Management System 1.0 database. An attacker could potentially gain access to sensitive payroll data, including employee names, addresses, social security numbers, and financial information. This data could be used for identity theft, financial fraud, or other malicious purposes. The vulnerability also allows for data modification or deletion, potentially disrupting payroll operations.

Recommendation

• Inspect web server logs for requests to /manage_user.php containing suspicious characters or SQL keywords in the ID parameter to detect potential exploitation attempts (see rule: “Detect SQL Injection Attempts via URI”).
• Monitor web server error logs for SQL errors that may indicate successful or attempted SQL injection (see rule: “Detect SQL Errors”).
• Apply appropriate input validation and sanitization techniques to the ID parameter in the /manage_user.php file to prevent SQL injection attacks.
