Exploitability
| CWE ID | Description |
|---|---|
| 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. |
| 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. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-4237 is a critical SQL injection vulnerability found in the Free Hotel Reservation System version 1.0, specifically in the file /hotel/admin/mod_reports/index.php.'}, {'type': 'paragraph', 'content': "The vulnerability arises due to improper handling and inadequate validation of user-supplied input parameters (notably the 'Home' or 'start' parameter), which allows attackers to inject malicious SQL code."}, {'type': 'paragraph', 'content': 'This flaw enables remote attackers to execute arbitrary SQL commands without authentication, potentially accessing, modifying, or deleting sensitive data in the database.'}, {'type': 'paragraph', 'content': 'Exploitation techniques include Boolean-based blind SQL injection, error-based SQL injection, stacked queries, and time-based blind SQL injection, with publicly available proof-of-concept exploits.'}] [1, 2, 3]
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to sensitive data, data leakage, data tampering, and potential full system compromise.
Attackers can view, modify, or delete critical information stored in the database, which compromises data integrity and system security.
The vulnerability can also lead to service disruption and loss of availability.
Since no authentication is required to exploit this flaw, it poses a high risk of remote exploitation.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': "The vulnerability can be detected by testing the /hotel/admin/mod_reports/index.php endpoint for SQL injection via the 'start' POST parameter.

What immediate steps should I take to mitigate this vulnerability?
Immediate remediation steps to mitigate this SQL injection vulnerability include:
- Implement prepared statements with parameter binding to separate SQL code from user input.
- Apply strict input validation and filtering to ensure inputs conform to expected formats.
- Minimize database user permissions by avoiding the use of high-privilege accounts such as root or admin for routine operations.
- Conduct regular security audits to detect and fix vulnerabilities promptly.
If possible, replace the affected software with an alternative product as no known mitigations or countermeasures have been published.
