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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-39109 is a SQL Injection vulnerability in the Apartment Visitors Management System version 1.1, specifically in the username parameter of the login page (index.php).
This vulnerability allows an unauthenticated attacker to manipulate backend SQL queries during authentication by injecting malicious SQL code through the username field.
The root cause is the lack of input sanitization and unsafe query construction methods, which enable unauthorized execution of database queries.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL Injection vulnerability in the Apartment Visitors Management System allows unauthorized attackers to access and retrieve sensitive database contents. This unauthorized data disclosure can lead to violations of data protection regulations such as GDPR and HIPAA, which mandate the protection of personal and sensitive information.
Because the vulnerability enables attackers to manipulate backend SQL queries and access sensitive data without authentication, it undermines the confidentiality and integrity requirements of these standards, potentially resulting in non-compliance and legal consequences.
How can this vulnerability impact me? :
This vulnerability can lead to unauthorized access to sensitive database contents by attackers without needing to authenticate.
Attackers can retrieve confidential information stored in the database, potentially compromising user data and system integrity.
Such unauthorized data disclosure can result in data breaches, loss of trust, and potential further exploitation of the system.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
The SQL Injection vulnerability in the username parameter of the login page can be detected by using tools such as Burp Suite and SQLmap to send crafted requests that attempt injection via the username field.
Using SQLmap, you can test the login page by targeting the username parameter to check for SQL injection. For example, a command might look like: sqlmap -u "http://targetsite/index.php" --data="username=admin&password=pass" -p username --batch
Burp Suite can be used to intercept and modify login requests to inject SQL payloads into the username parameter and observe the responses for signs of injection.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include implementing prepared statements (parameterized queries) to safely handle the username input and prevent SQL injection.
Additionally, validate and sanitize all user inputs, apply output encoding, and follow OWASP secure coding practices to reduce the risk of injection attacks.
