CVE-2025-6482: Simple Pizza Ordering System SQLi Flaw

CVE-2025-6482 Overview

A critical SQL Injection vulnerability has been discovered in the Simple Pizza Ordering System version 1.0 developed by code-projects. The vulnerability exists in the /edituser-exec.php file, where improper handling of the userid parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to extract sensitive user data, modify database records, or potentially gain unauthorized access to the underlying system through the vulnerable userid parameter in /edituser-exec.php.

Technical Details for CVE-2025-6482

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the /edituser-exec.php file. The application fails to adequately sanitize or parameterize the userid argument before incorporating it into SQL queries. This allows attackers to craft malicious input that modifies the intended query logic, enabling them to bypass authentication, extract sensitive data from the database, or perform unauthorized database operations.

The vulnerability is remotely exploitable without authentication, making it particularly dangerous for internet-facing deployments. An attacker can send specially crafted HTTP requests containing SQL injection payloads in the userid parameter to manipulate backend database queries.

Root Cause

The root cause of this vulnerability is the improper input validation and lack of parameterized queries in the /edituser-exec.php file. The userid parameter is directly concatenated into SQL queries without proper sanitization, allowing injection attacks. This represents a classic injection flaw (CWE-74) where untrusted data is sent to an interpreter as part of a command or query.

Attack Vector

The attack vector is network-based, allowing remote exploitation. An attacker can send malicious HTTP requests to the /edituser-exec.php endpoint with a crafted userid parameter containing SQL injection payloads. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. The attack requires no authentication and no user interaction, making it trivially exploitable.

The vulnerability can be exploited by sending HTTP POST or GET requests to the vulnerable endpoint with manipulated userid values such as ' OR '1'='1 or UNION-based payloads to extract database contents. For detailed technical information, refer to the GitHub CVE Issue Discussion or VulDB #313590.

Detection Methods for CVE-2025-6482

Indicators of Compromise

• HTTP requests to /edituser-exec.php containing SQL metacharacters in the userid parameter (e.g., single quotes, double dashes, UNION, SELECT keywords)
• Database error messages appearing in application logs or responses indicating malformed SQL queries
• Unusual database query patterns or execution times in database audit logs
• Unexpected data access or modification in user-related database tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP parameters targeting /edituser-exec.php
• Implement application-layer logging to capture all requests to the vulnerable endpoint and monitor for suspicious parameter values
• Enable database query logging and alerting for anomalous query patterns or syntax errors
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /edituser-exec.php with varying userid parameter values
• Configure SIEM alerts for database authentication failures or privilege escalation attempts
• Implement rate limiting on the vulnerable endpoint to slow automated exploitation attempts
• Review database audit logs for unauthorized SELECT, INSERT, UPDATE, or DELETE operations

How to Mitigate CVE-2025-6482

Immediate Actions Required

• Take the Simple Pizza Ordering System offline or restrict network access to the vulnerable endpoint until patched
• Implement input validation and parameterized queries (prepared statements) for all database operations involving user-supplied data
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as a temporary mitigation
• Audit database for signs of compromise and restore from clean backups if unauthorized access is detected

Patch Information

No official vendor patch has been released at this time. Organizations using the Simple Pizza Ordering System 1.0 should contact the vendor or review the Code Projects Security Resources for updates. In the absence of an official fix, implementing manual code remediation using parameterized queries is strongly recommended.

Workarounds

• Restrict network access to the application using firewall rules to limit exposure to trusted IP addresses only
• Implement server-side input validation to reject userid values containing SQL metacharacters
• Deploy a reverse proxy with WAF capabilities to filter malicious requests before they reach the application
• Consider temporarily disabling the user edit functionality until proper input sanitization can be implemented
