| 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
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 unauthorized access and manipulation of the database, which can lead to leakage of sensitive information and data modification or deletion.
Such unauthorized access and data breaches can result in non-compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data.
Failure to secure the system against this vulnerability could lead to violations of data protection requirements, potentially resulting in legal penalties, loss of customer trust, and damage to business continuity.
Can you explain this vulnerability to me?
CVE-2026-5555 is a critical SQL injection vulnerability found in version 1.0 of the Concert Ticket Reservation System, specifically in the file /ConcertTicketReservationSystem-master/login.php. The vulnerability occurs because the 'Email' parameter is improperly handled and directly incorporated into SQL queries without proper input validation or sanitization.
This flaw allows attackers to inject malicious SQL code remotely, which can manipulate database queries in unauthorized ways.
How can this vulnerability impact me? :
Exploitation of this SQL injection vulnerability can lead to unauthorized access to the database, leakage of sensitive information, modification or deletion of data, full system compromise, and potential disruption of services.
These impacts threaten both system security and business continuity.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the 'Email' parameter in POST requests to the endpoint `/ConcertTicketReservationSystem-master/process_login.php` for SQL injection flaws.
A practical approach is to use automated SQL injection testing tools such as sqlmap, which has been confirmed to successfully inject SQL commands via this parameter.
Example command using sqlmap to test the vulnerability:
- sqlmap -u "http://target/ConcertTicketReservationSystem-master/process_login.php" --data="[email protected]&Password=pass" -p Email
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 SQL injection.
- Enforce strict input validation and filtering to ensure inputs conform to expected formats.
- Minimize database user privileges by avoiding the use of high-privilege accounts (such as root or admin) for routine database operations.
- Conduct regular security audits to detect and address vulnerabilities promptly.
