SQL Injection in SourceCodester Pizzafy Ecommerce System

Executive Summary

CVE-2026-7409 is a high-severity SQL injection vulnerability in the Pizzafy Ecommerce System 1.0, specifically in the save_user function accessed via the /admin/ajax.php?action=save_user endpoint.

The vulnerability occurs because the username parameter is not properly sanitized before being embedded directly into SQL queries. This allows an attacker to inject malicious SQL code through POST requests.

Exploiting this flaw can enable attackers to extract sensitive database information, manipulate or delete records, and potentially escalate privileges by triggering database errors that reveal information.

The issue arises from the lack of use of prepared statements or parameterized queries, which are necessary to prevent SQL injection attacks.

Detection Guidance

This vulnerability can be detected by testing the `/pizzafy/admin/ajax.php?action=save_user` endpoint for SQL injection flaws, specifically by manipulating the username parameter in POST requests.

An effective detection method is to send crafted POST requests that include SQL injection payloads designed to trigger database errors or reveal database information.

• Use curl to send a POST request with a payload that attempts to cause an SQL error, for example: curl -X POST -d "username=' OR 1=1-- " https://target/pizzafy/admin/ajax.php?action=save_user
• Observe the response for database error messages or unusual behavior indicating SQL injection vulnerability.

Automated tools or scripts can also be used to test this endpoint by injecting typical SQL payloads and analyzing the responses for signs of vulnerability.

Impact Analysis

This vulnerability can have several serious impacts:

• Attackers can extract sensitive information from the database, such as user data.
• Attackers can manipulate or delete database records, potentially disrupting business operations.
• Privilege escalation is possible by abusing error messages, which could allow attackers to gain higher access rights.
• Since the attack can be launched remotely, it increases the risk of unauthorized access without physical presence.

Compliance Impact

The SQL injection vulnerability in Pizzafy Ecommerce System 1.0 allows attackers to extract sensitive database information, manipulate or delete records, and potentially escalate privileges. Such unauthorized access and manipulation of sensitive data can lead to violations of data protection regulations like GDPR and HIPAA, which require the protection of personal and sensitive information against unauthorized access and breaches.

Failure to properly sanitize inputs and prevent SQL injection can result in data breaches, which may trigger legal and regulatory consequences under these standards, including requirements for breach notification, risk mitigation, and potential penalties.

Mitigation Strategies

Immediate mitigation steps include applying the fixed code that replaces direct SQL queries with prepared statements using parameterized inputs to properly sanitize user input.

If a patch or update is available for Pizzafy Ecommerce System 1.0, it should be applied promptly to prevent exploitation.

As a temporary measure, restrict access to the vulnerable endpoint `/pizzafy/admin/ajax.php?action=save_user` to trusted IP addresses or disable it if not in use.

Additionally, monitor logs for suspicious activity and consider implementing web application firewalls (WAF) rules to block SQL injection attempts targeting this endpoint.
