CVE-2026-10704: Pizzafy E-Commerce System SQLi Vulnerability

CVE-2026-10704 Overview

CVE-2026-10704 is a SQL injection vulnerability in SourceCodester Pizzafy E-Commerce System 1.0. The flaw resides in the Login function of /admin/admin_class_novo.php within the Administrative Control Panel component. Attackers manipulate the Username argument to inject arbitrary SQL statements against the backend database. The vulnerability is exploitable remotely without authentication or user interaction. The exploit is publicly available, increasing the likelihood of opportunistic abuse against exposed installations. The issue is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact

Unauthenticated remote attackers can inject SQL into the admin login flow, enabling authentication bypass and disclosure or modification of administrative database content.

Affected Products

• SourceCodester Pizzafy E-Commerce System 1.0
• Component: Administrative Control Panel (/admin/admin_class_novo.php)
• Vulnerable function: Login

Technical Details for CVE-2026-10704

Vulnerability Analysis

The vulnerability exists in the administrative login handler of the Pizzafy E-Commerce System. The Login function in /admin/admin_class_novo.php concatenates the user-supplied Username parameter directly into a SQL query without parameterization or input sanitization. An attacker submits crafted input to the admin login form to alter the structure of the query.

Because the login routine evaluates the result set to determine authentication success, an injection payload that forces the query to return a row enables authentication bypass. The attack requires no prior credentials and no user interaction, and it can be launched across the network against any reachable instance.

Root Cause

The root cause is the absence of prepared statements and input validation in the admin authentication path. The Username argument is interpolated into the SQL statement as a raw string, allowing special characters such as single quotes, comments, and Boolean operators to change query semantics. This matches the [CWE-74] pattern of improper neutralization of special elements.

Attack Vector

A remote, unauthenticated attacker sends a POST request to the admin login endpoint with a SQL payload in the Username field. Typical payloads use tautology-based injection (for example, appending OR 1=1) to bypass credential verification, or UNION SELECT constructs to exfiltrate data from other tables. Successful exploitation grants administrative session access to the e-commerce backend.

A public proof-of-concept is documented in the GitHub Vulnerability Report and tracked in VulDB CVE-2026-10704. No verified exploit code is reproduced here.

Detection Methods for CVE-2026-10704

Indicators of Compromise

• POST requests to /admin/admin_class_novo.php containing SQL metacharacters such as ', --, #, OR, or UNION in the Username parameter.
• Successful admin authentication events without a corresponding valid credential lookup in application logs.
• Database error messages referencing SQL syntax exceptions originating from the admin login path.
• Unexpected administrative session creation from previously unseen client IP addresses.

Detection Strategies

• Inspect HTTP request bodies sent to admin endpoints for SQL injection patterns and tautologies.
• Correlate web server access logs with database query logs to identify malformed or unusually long queries triggered by login attempts.
• Deploy a web application firewall (WAF) with SQL injection signatures tuned to the /admin/ path of the Pizzafy application.

Monitoring Recommendations

• Alert on repeated failed admin logins followed by a sudden successful login from the same source address.
• Monitor for anomalous SELECT, UNION, or error-based queries against the user or admin tables.
• Track outbound data volumes from the database host to detect bulk extraction attempts.

How to Mitigate CVE-2026-10704

Immediate Actions Required

• Restrict network access to /admin/ paths using IP allowlists or VPN-only access until a fix is applied.
• Deploy WAF rules that block SQL metacharacters in the Username parameter of the admin login endpoint.
• Rotate all administrative credentials and review admin account activity for unauthorized changes.
• Audit the database for unexpected new accounts, modified product data, or exfiltration indicators.

Patch Information

As of the NVD publication date (2026-06-03), no vendor patch has been published by SourceCodester for Pizzafy E-Commerce System 1.0. Operators should track the VulDB Vulnerability #368017 entry and the SourceCodester Resources site for updates. Until an official fix is released, code-level remediation requires replacing string concatenation in the Login function with parameterized queries or prepared statements.

Workarounds

• Modify /admin/admin_class_novo.php to use PDO prepared statements or mysqli parameter binding for the Username and password values.
• Apply server-side input validation that rejects non-alphanumeric characters in usernames before the value reaches the SQL layer.
• Place the admin panel behind an authenticating reverse proxy that enforces an additional credential check.
• Disable or remove the affected administrative endpoint if it is not required in production.

# Example: Nginx access restriction for the admin panel
location /admin/ {
    allow 10.0.0.0/8;
    deny all;
    proxy_pass http://pizzafy_backend;
}
