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-2026-5206 is a SQL Injection vulnerability found in the Simple Gym Management System version 1.0, specifically in the payment handling component. The issue occurs because user inputs such as Payment_id, Amount, customer_id, payment_type, and customer_name are directly concatenated into an SQL INSERT statement without any filtering or sanitization.
This allows an attacker to inject malicious SQL code through these parameters, potentially manipulating payment data in the database.
For example, by setting Payment_id to a crafted value like ' OR '1'='1, an attacker can bypass intended logic and alter or extract payment information.
The vulnerability is considered high severity due to its potential to compromise financial data.
How can this vulnerability impact me? :
This vulnerability can lead to unauthorized manipulation of payment records, including altering payment amounts or forging payment entries.
An attacker could also extract all payment information stored in the database, leading to potential financial loss and data compromise.
Such exploitation can undermine the integrity and confidentiality of your payment data, causing operational and reputational damage.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by analyzing the input parameters to the payment functionality, specifically looking for SQL injection attempts in the parameters Payment_id, Amount, customer_id, payment_type, and customer_name.
One way to detect exploitation attempts is to monitor web server logs or application logs for suspicious input patterns such as SQL injection payloads like "' OR '1'='1" in these parameters.
Additionally, you can use SQL injection detection tools or scanners against the payment endpoint to test if the inputs are vulnerable.
- Use tools like sqlmap to test the payment parameters for SQL injection.
- Check web server logs for suspicious query strings or POST data containing SQL injection patterns.
- Example command with sqlmap: sqlmap -u "http://targetsite/payment.php" --data "Payment_id=1&Amount=100&customer_id=1&payment_type=card&customer_name=John" --risk=3 --level=5
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability immediately, you should prevent SQL injection by avoiding direct concatenation of user inputs into SQL queries.
Specifically, implement prepared statements with parameterized queries using PDO or MySQLi in the payment handler code.
Additionally, apply strict input validation and proper escaping on all user-supplied data before using it in SQL statements.
If immediate code changes are not possible, consider applying web application firewall (WAF) rules to block common SQL injection payloads targeting the payment parameters.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the Simple Gym Management System's payment handler can lead to unauthorized access and manipulation of payment data, including financial information and customer details.
Such unauthorized access and potential data compromise can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and financial data against breaches and unauthorized manipulation.
Failure to remediate this vulnerability could result in violations of these regulations due to exposure or alteration of sensitive customer payment information.
