itsourcecode Payroll Management System 1.0 SQL Injection Vulnerability

itsourcecode Payroll Management System 1.0 is vulnerable to SQL injection in the /view_employee.php script. This vulnerability, identified as CVE-2026-5238, allows a remote attacker to inject arbitrary SQL commands by manipulating the ID parameter. Publicly available exploits exist, increasing the risk of exploitation. Successful exploitation could lead to unauthorized data access, modification, or deletion within the payroll database. This poses a significant threat to organizations using the affected software, potentially compromising sensitive employee information. Defenders need to implement immediate mitigation strategies to prevent potential attacks.

Attack Chain

1. Attacker identifies an instance of itsourcecode Payroll Management System 1.0.
2. Attacker crafts a malicious SQL injection payload targeting the ID parameter in the /view_employee.php file.
3. The attacker sends an HTTP GET or POST request to /view_employee.php with the crafted SQL injection payload in the ID parameter (e.g., /view_employee.php?ID=1' UNION SELECT ...).
4. The application fails to properly sanitize the input, passing the malicious SQL query to the database.
5. The database executes the injected SQL command, potentially returning sensitive data or allowing data modification.
6. The attacker retrieves sensitive data from the database, such as employee usernames, passwords, social security numbers, and salary information.
7. The attacker may further escalate the attack by modifying or deleting data within the payroll system.
8. The attacker achieves complete control over the payroll database, potentially leading to financial fraud or data breaches.

Impact

Successful exploitation of this SQL injection vulnerability allows attackers to access and manipulate sensitive payroll data. This could lead to data breaches, financial fraud, and reputational damage. The impact includes unauthorized access to employee personal information, modification of payroll records, and potential theft of funds. Given the public availability of exploits, organizations using itsourcecode Payroll Management System 1.0 are at immediate risk. The vulnerability could impact any organization using this software.

Recommendation

• Inspect web server logs for suspicious requests to /view_employee.php containing SQL syntax in the ID parameter and deploy the Sigma rule.
• Apply input validation and sanitization to the ID parameter in /view_employee.php to prevent SQL injection, as indicated by CVE-2026-5238.
• Monitor network traffic for unusual database activity originating from the web server and deploy the Sigma rule.
• Deploy the provided Sigma rule to detect exploitation attempts and tune it to your environment.
• Apply web application firewall (WAF) rules to block known SQL injection attack patterns.
