CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is a SQL injection flaw in the Sales and Inventory System 1.0 by itsourcecode. It exists in the file /pages/cust_pos_trans.php where the 'firstname' parameter is not properly sanitized before being used in SQL queries. Attackers can manipulate this parameter to inject malicious SQL code, potentially leading to unauthorized database access, data theft, or system compromise.

Detection Guidance

To detect SQL injection vulnerabilities like CVE-2026-90525, inspect the /pages/cust_pos_trans.php file for unsanitized user input handling. Test the 'firstname' parameter by appending SQL commands like ' OR '1'='1 to input fields. Use tools like SQLmap to automate detection by running: sqlmap -u 'http://target.com/pages/cust_pos_trans.php?firstname=test' --batch.

Impact Analysis

If exploited, this vulnerability could allow attackers to access, modify, or delete sensitive data in the database. They could also gain full control of the system, disrupt services, or use the database for further attacks. Attackers need valid credentials but can leverage this to escalate privileges or bypass authentication.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by enabling unauthorized access to personal or health data. GDPR requires protection of personal data, while HIPAA mandates safeguards for health information. A breach could result in legal penalties, fines, and reputational damage due to failure to meet these regulatory standards.

Mitigation Strategies

Immediately implement prepared statements with parameter binding for all database queries. Apply strict input validation to sanitize the 'firstname' parameter. Restrict database user permissions to the minimum required. Conduct a full security audit of the application and update to the latest patched version if available.
