CVE-2026-7227: Pizzafy Ecommerce System SQLi Vulnerability

CVE-2026-7227 Overview

A SQL injection vulnerability has been identified in SourceCodester Pizzafy Ecommerce System version 1.0. The vulnerability exists in the Login function of the file /admin/ajax.php?action=login, where improper handling of the e-mail parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to bypass authentication, extract sensitive data, or potentially compromise the underlying database server.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to bypass authentication, access sensitive customer data, and potentially gain full control of the ecommerce application database.

Technical Details for CVE-2026-7227

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs in the admin login functionality of the Pizzafy Ecommerce System. The application fails to properly sanitize user-supplied input in the e-mail parameter before incorporating it into SQL queries. This allows attackers to manipulate database queries by injecting malicious SQL code through the login form.

The vulnerability is particularly concerning because it affects the administrative authentication mechanism. Successful exploitation could allow attackers to bypass login authentication entirely, enumerate database contents, extract customer payment information, or execute administrative operations without proper credentials.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries in the Login function. When processing login requests at /admin/ajax.php?action=login, the application directly concatenates user input from the e-mail field into SQL statements without proper sanitization or the use of prepared statements. This classic injection pattern allows malicious SQL syntax to be interpreted as part of the query structure rather than as data.

Attack Vector

The attack can be executed remotely over the network without any authentication requirements. An attacker can submit specially crafted input through the email parameter in the admin login form. By injecting SQL syntax such as single quotes, comment characters, or UNION statements, the attacker can alter the logic of the underlying query.

Typical exploitation scenarios include:

Authentication bypass using payloads like ' OR '1'='1' -- in the email field
Data exfiltration through UNION-based injection to retrieve database contents
Time-based blind SQL injection to enumerate database structure
Potential escalation to command execution if database permissions allow

The exploit for this vulnerability has been publicly disclosed, increasing the risk of widespread exploitation. For technical details, refer to the GitHub SQL Injection Submission.

Detection Methods for CVE-2026-7227

Indicators of Compromise

Unusual login attempts to /admin/ajax.php?action=login with SQL injection patterns in the email field
Database error messages in application logs indicating SQL syntax errors
Unexpected database queries or query execution times in database audit logs
Successful admin panel access from unrecognized IP addresses or without valid credentials

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in POST parameters
Monitor access logs for requests to /admin/ajax.php containing suspicious characters such as single quotes, double dashes, or UNION keywords
Enable database query logging and alert on anomalous query patterns or syntax errors
Deploy intrusion detection signatures for common SQL injection attack payloads

Monitoring Recommendations

Enable verbose logging on the web server for all requests to administrative endpoints
Configure database auditing to capture all queries executed against user authentication tables
Set up alerts for multiple failed login attempts followed by successful authentication
Monitor for data exfiltration patterns such as large result sets or unusual query timing

How to Mitigate CVE-2026-7227

Immediate Actions Required

Restrict access to the admin panel by IP whitelist or VPN until patching is complete
Implement a Web Application Firewall with SQL injection protection rules
Disable or rename the vulnerable /admin/ajax.php endpoint if not immediately required
Review database access logs for signs of prior exploitation

Patch Information

As of the last update, no official patch has been released by SourceCodester for this vulnerability. Organizations using Pizzafy Ecommerce System should monitor the SourceCodester website for security updates. Given that SourceCodester provides open-source projects, administrators may need to implement code-level fixes manually.

Workarounds

Modify the Login function in /admin/ajax.php to use prepared statements with parameterized queries
Implement server-side input validation to reject email inputs containing SQL metacharacters
Add a Web Application Firewall rule to block requests with SQL injection patterns in the e-mail parameter
Consider migrating to a more actively maintained ecommerce platform if vendor support is unavailable
