| 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-2026-3730 is a critical SQL injection vulnerability found in the Free Hotel Reservation System version 1.0 by itsourcecode. The flaw exists in the handling of the parameters amen_id and rmtype_id in files such as /hotel/admin/mod_amenities/index.php and /hotel/admin/mod_room/index.php. Due to improper or absent input validation and sanitization, attackers can inject malicious SQL code remotely without authentication. This allows them to manipulate database queries, potentially leading to unauthorized access, data leakage, modification, deletion, or full system compromise.
Multiple SQL injection techniques can be used to exploit this vulnerability, including boolean-based blind, error-based, stacked queries, and time-based blind injections. Proof-of-concept exploits have been demonstrated using tools like sqlmap, confirming the vulnerability through manipulated POST requests.
Recommended remediation includes using prepared statements with parameter binding, enforcing strict input validation, minimizing database user privileges, and conducting regular security audits.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to the database, leakage of sensitive data, modification or deletion of data, and potential full system compromise. Attackers can disrupt services or manipulate data, threatening business continuity and system security.

What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps for CVE-2026-3730 include implementing secure coding practices and restricting database access.
- Use prepared statements with parameter binding to separate SQL code from user input, preventing injection.
- Enforce strict input validation and filtering to ensure that parameters like `amen_id` and `rmtype_id` conform to expected formats.
- Minimize database user privileges by avoiding the use of high-privilege accounts such as `root` or `admin` for routine operations.
- Conduct regular security audits and code reviews to detect and address vulnerabilities promptly.
Applying these measures immediately is essential to protect system security and maintain data integrity.
