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.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

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

Detection Guidance

To detect this SQL injection vulnerability, you can test the /pages/emp_transac.php endpoint with malicious input in the firstname parameter. Use tools like curl to send requests with SQL payloads such as ' OR '1'='1 or a time delay payload like '; IF (1=1) WAITFOR DELAY '0:0:5'--. Monitor responses for delays or errors indicating successful injection.

  • Example curl command: curl -X POST 'http://target.com/pages/emp_transac.php?action=add&firstname=test' OR '1'='1' --data 'other_params=value'
  • Use automated tools like SQLmap to scan for SQL injection: sqlmap -u 'http://target.com/pages/emp_transac.php?action=add&firstname=test' --batch
Impact Analysis

If exploited, this vulnerability could allow attackers to access, modify, or delete sensitive data in the database. They could steal user information, alter records, or disrupt system operations. The impact depends on the database contents and system permissions.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized data access or breaches. GDPR requires protecting personal data, while HIPAA mandates safeguarding health information. A successful exploit may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Immediately apply input validation and sanitization for the firstname parameter. Replace dynamic SQL queries with prepared statements using parameter binding. Restrict database user permissions to the minimum required. Conduct a security audit to identify other potential vulnerabilities.

  • Update the application to use prepared statements with parameterized queries for all SQL operations involving user input.
  • Implement strict input validation to reject any input containing SQL keywords or special characters in the firstname field.
  • Review and reduce database user privileges to limit potential damage from successful injections.
