Can you explain this vulnerability to me?

CVE-2026-30530 is a SQL Injection vulnerability found in the Online Food Ordering System version 1.0, specifically in the Actions.php file within the save_customer action. The issue arises because the application does not properly sanitize the "username" parameter received via HTTP POST requests before using it in SQL queries.

This improper input handling allows attackers to inject malicious SQL commands into the database queries. The backend database is SQLite, and attackers can exploit this vulnerability using Boolean-based blind SQL injection or time-based blind SQL injection techniques.

Exploitation can be done by sending specially crafted inputs to the username parameter, which can manipulate the database queries to reveal sensitive information or alter database behavior.

How can this vulnerability impact me? :

This vulnerability can have severe impacts including:

• Data exfiltration: Attackers can dump the entire SQLite database, gaining access to sensitive customer personally identifiable information (PII), admin credentials, and order details.
• Authentication bypass: Attackers may manipulate login logic to gain unauthorized access.
• Database enumeration: Attackers can discover the database schema and table structures, which can facilitate further attacks.

Overall, this vulnerability poses a significant risk to the confidentiality and integrity of the system's data.

How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability can be detected by targeting the "username" parameter in HTTP POST requests to the save_customer action in the Actions.php file of the Online Food Ordering System v1.0. Tools like sqlmap can be used to automate the detection of SQL Injection.

Example sqlmap commands include testing the "username" POST parameter with appropriate headers and cookies to confirm injection points.

• Boolean-based blind injection payload example: username=customer1' AND 4611=4611 AND 'YtZs'='YtZs
• Time-based blind injection (SQLite-specific) payload example: username=customer1' AND 5832=LIKE(CHAR(65,66,67,68,69,70,71),UPPER(HEX(RANDOMBLOB(500000000/2)))) AND 'Zrsm'='Zrsm

By running sqlmap with these payloads against the username parameter, you can confirm if the system is vulnerable by observing the responses and database backend identification.

How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

The SQL Injection vulnerability in the Online Food Ordering System allows attackers to exfiltrate sensitive customer personally identifiable information (PII), admin credentials, and order details by dumping the entire SQLite database.

Such unauthorized access and potential data breaches can lead to non-compliance with common standards and regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive data.

Therefore, this vulnerability poses a significant risk to the confidentiality and integrity of data, potentially resulting in violations of data protection requirements and regulatory obligations.

What immediate steps should I take to mitigate this vulnerability?

To mitigate the SQL Injection vulnerability in the Online Food Ordering System v1.0, immediate steps include:

• Avoid using the vulnerable version of the software until a patch or update is available.
• Restrict access to the customer registration and update interfaces, especially the save_customer action in Actions.php.
• Implement input validation and sanitization on the "username" parameter to prevent malicious SQL commands.
• Use prepared statements or parameterized queries in the backend to handle user inputs safely.
• Monitor logs for suspicious activity targeting the username parameter or unusual database queries.
• If possible, deploy web application firewalls (WAFs) to detect and block SQL injection attempts.
