| CWE ID | Description |
|---|---|
| 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. |
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-5634 is a critical SQL injection vulnerability found in version 1.0 of the Projectworlds Car Rental System, specifically in the file /book_car.php. The vulnerability occurs because the fname parameter is improperly handled and directly used in SQL queries without proper input validation or sanitization.
This flaw allows attackers to inject malicious SQL code, which can manipulate database queries in unauthorized ways.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Implement prepared statements (parameterized queries) to ensure user inputs are treated as data, preventing SQL injection.
- Apply strict input validation and filtering on the fname parameter to ensure inputs conform to expected formats.
- Limit database user permissions to the minimum necessary, avoiding use of high-privilege accounts for routine operations.
- Conduct regular security audits of code and systems to detect and remediate vulnerabilities promptly.
How can this vulnerability impact me? :
The impact of this vulnerability is severe. Attackers exploiting it can gain unauthorized access to the database, leak sensitive information, alter or delete data, take full control over the system, and potentially disrupt service availability.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability is a SQL injection in the /book_car.php file via the fname parameter. Detection can involve testing this parameter for SQL injection vulnerabilities.
- Use tools like sqlmap to test the fname parameter for SQL injection, e.g., sqlmap -u "http://target/book_car.php?fname=test" --batch
- Manually test by injecting SQL syntax in the fname parameter, such as adding a single quote (') or SQL keywords to observe error messages or unexpected behavior.
- Monitor network traffic for suspicious requests targeting /book_car.php with unusual or malformed fname parameter values.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the Projectworlds Car Rental System allows attackers to gain unauthorized access to the database, potentially leading to leakage, alteration, or deletion of sensitive data. Such unauthorized data exposure and manipulation can result in non-compliance with common standards and regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive information.
Failure to protect data integrity and confidentiality due to this vulnerability could lead to violations of data protection requirements, resulting in legal and financial consequences under these regulations.
