Can you explain this vulnerability to me?

CVE-2026-7266 is a high-severity SQL Injection vulnerability found in SourceCodester Pizzafy Ecommerce System version 1.0. It occurs in the save_order function at the endpoint /admin/ajax.php?action=save_order due to improper sanitization of the id parameter and user_id column in an SQL query.

The vulnerability arises because user-supplied input is directly embedded into an SQL query without proper validation or parameterization. Attackers can exploit this by injecting malicious SQL commands that manipulate the database.

Using error-based SQL injection techniques, attackers can extract sensitive information such as database names, table names, column structures, usernames, and password hashes. They can also modify or delete records, escalate privileges by hijacking sessions, and cause denial of service through mass deletion.

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

The SQL injection vulnerability in Pizzafy Ecommerce System 1.0 allows attackers to extract sensitive information such as database names, table structures, usernames, and password hashes. This exposure of confidential data can lead to violations of data protection regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive information.

Additionally, the vulnerability enables unauthorized modification or deletion of records and privilege escalation, which can compromise data integrity and availability—key requirements under many compliance standards.

Failure to remediate such vulnerabilities may result in non-compliance with these regulations, potentially leading to legal penalties, loss of customer trust, and damage to organizational reputation.

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

This vulnerability can be detected by monitoring for suspicious SQL injection attempts targeting the /pizzafy/admin/ajax.php?action=save_order endpoint, specifically looking for manipulation of the id parameter.

One way to detect exploitation attempts is to analyze web server logs for unusual POST requests containing SQL injection payloads such as error-based injection patterns.

Example detection commands include using tools like curl or wget to simulate the attack payload and observe responses, or using network monitoring tools to filter for suspicious traffic.

• Using curl to test the vulnerable endpoint with a crafted payload: curl -X POST -d "id=-8 OR extractvalue(1,concat(0x7e,database())) -- " http://target/pizzafy/admin/ajax.php?action=save_order
• Using grep to search web server logs for suspicious SQL injection patterns: grep -i 'extractvalue' /var/log/apache2/access.log
• Using intrusion detection systems (IDS) or web application firewalls (WAF) to detect and alert on SQL injection signatures targeting the id parameter.

What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include replacing vulnerable SQL queries with prepared statements using parameterized queries to safely bind user inputs.

Validate and sanitize all input parameters, especially the id parameter, to prevent injection of malicious SQL code.

Restrict database user privileges to minimize potential damage from SQL injection attacks.

Avoid exposing detailed database error messages to end users to prevent attackers from gaining useful information.

Implement monitoring and logging to detect suspicious activities and conduct regular security testing, including penetration tests and code reviews.
