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 is a SQL injection vulnerability in the Sales and Inventory System 1.0. The flaw exists in the /pages/cust_transac.php file where the 'firstname' parameter is not properly sanitized. Attackers can inject malicious SQL code through this parameter to manipulate database queries.

Detection Guidance

To detect this SQL injection vulnerability, test the 'firstname' parameter in /pages/cust_transac.php by sending crafted inputs like single quotes or SQL keywords. Use tools like SQLmap with: sqlmap -u 'http://target.com/pages/cust_transac.php?action=add&firstname=test' --data='firstname=test' --batch. Alternatively, manually test with curl: curl 'http://target.com/pages/cust_transac.php?action=add&firstname=1'' OR '1'='1' --user-agent 'Mozilla'.

Impact Analysis

An attacker could exploit this to access, modify, or delete sensitive data in the database. They might steal customer information, alter inventory records, or even take control of the system. The attack requires valid login credentials but can be performed remotely.

Compliance Impact

This vulnerability could lead to violations of GDPR (data protection) and HIPAA (health data privacy) by exposing sensitive personal or medical information. Organizations may face legal penalties, fines, or reputational damage if this flaw results in a data breach.

Mitigation Strategies

Immediately update the application to use prepared statements with parameter binding for all database queries. Implement strict input validation to reject any non-alphabetic characters in the 'firstname' field. Restrict database user permissions to the minimum required. Conduct a full security audit of the application to identify similar vulnerabilities.
