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?
This vulnerability is a SQL injection flaw found in the Concert Ticket Reservation System version 1.0, specifically in the file /ConcertTicketReservationSystem-master/process_search.php. It occurs because the 'searching' parameter is improperly handled and directly included in SQL queries without proper input validation or sanitization.
Attackers can exploit this flaw remotely without authentication by injecting malicious SQL code through the 'searching' parameter. This allows them to manipulate database queries in various ways, such as Boolean-based blind SQL injection, time-based blind SQL injection, and UNION-based SQL injection.
Exploitation can lead to unauthorized database access, data extraction, modification or deletion of records, and potentially full control over the system.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to sensitive data stored in the database, data corruption or deletion, and disruption of business operations.
- Attackers can extract confidential information from the database.
- Data integrity can be compromised by unauthorized modification or deletion of records.
- The system's security can be undermined, potentially allowing attackers to gain full control over the application.
- Business continuity may be affected due to data loss or system downtime caused by exploitation.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This SQL injection vulnerability can be detected by testing the `searching` POST parameter in the file `/ConcertTicketReservationSystem-master/process_search.php` for injection flaws.
- Use payloads such as `searching=-7882' OR 1599=1599 #` to test for Boolean-based blind SQL injection.
- Use payloads like `searching=1' AND (SELECT SLEEP(5))--` to test for Time-based blind SQL injection.
- Use UNION-based SQL injection payloads such as `searching=1' UNION ALL SELECT NULL,NULL,CONCAT(...) ,NULL #` to check for data extraction vulnerabilities.
- Use tools like sqlmap to automate detection by crafting POST requests targeting the `searching` parameter.
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 and prevent injection.
- Enforce strict input validation and filtering to ensure inputs conform to expected formats.
- Minimize database user privileges by avoiding use of high-privilege accounts (e.g., root or admin) for routine operations.
- Conduct regular security audits 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 the Concert Ticket Reservation System allows attackers to perform unauthorized database access, extract sensitive data, and modify or delete records. Such unauthorized access and potential data breaches can lead to non-compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive information.
Failure to secure the system against this vulnerability may result in exposure of personal data, violating data protection requirements and potentially leading to legal and financial consequences under these regulations.
