Exploitability
| 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-2026-5637 is a critical SQL injection vulnerability found in version 1.0 of the Projectworlds Car Rental System, specifically in the file message_admin.php. The vulnerability occurs because the message parameter is improperly handled and directly included in SQL queries without proper input validation or sanitization.
This flaw allows attackers to inject malicious SQL code remotely, without needing any authentication or authorization, enabling them to manipulate database queries.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to unauthorized database access, allowing attackers to extract sensitive information, modify or delete data, and potentially take full control of the system.
Such impacts include data leakage, data tampering, and disruption of service, which can severely affect the integrity, confidentiality, and availability of the system.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the vulnerable endpoint `/message_admin.php` for SQL injection flaws, specifically by manipulating the `message` parameter.
A proof-of-concept involves using a time-based blind SQL injection payload such as: `message=nihao' RLIKE SLEEP(5) AND 'ixEP'='ixEP` which causes a delay in the database response, confirming the vulnerability.
The sqlmap tool can be used to automate detection by targeting the vulnerable endpoint.
- Use sqlmap against the endpoint: `sqlmap -u "http://target/message_admin.php?message=anything" --delay=5 --technique=T --dbs`
- Manually test with curl or browser by injecting payloads like: `http://target/message_admin.php?message=nihao'%20RLIKE%20SLEEP(5)%20AND%20'ixEP'='ixEP` and observe response delays.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include:
- Implement prepared statements with parameter binding to separate SQL code from user input, preventing injection.
- Enforce strict input validation and filtering to ensure inputs conform to expected formats.
- Limit database user permissions to the minimum necessary, avoiding use of high-privilege accounts like root or admin for routine operations.
- Conduct regular security audits of code and systems to detect and address vulnerabilities promptly.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in Projectworlds Car Rental System 1.0 can lead to unauthorized database access, data leakage, and data tampering. Such impacts can compromise the confidentiality and integrity of sensitive personal data.
This type of vulnerability can negatively affect compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal data against unauthorized access and breaches.
Failure to address this vulnerability may result in violations of these regulations due to potential exposure or alteration of protected data.
