CVE-2025-6936: Simple Pizza Ordering System SQLi Flaw

CVE-2025-6936 Overview

A SQL injection vulnerability has been identified in code-projects Simple Pizza Ordering System 1.0. The vulnerability exists in the /addpro.php file where the manipulation of the ID argument leads to SQL injection. This is a network-based attack that can be initiated remotely, posing significant risks to data confidentiality, integrity, and availability. The exploit has been publicly disclosed, increasing the urgency for organizations using this software to take immediate action.

Critical Impact

Attackers can exploit this SQL injection vulnerability remotely to extract sensitive data, modify database contents, or potentially achieve full database compromise through the vulnerable /addpro.php endpoint.

Technical Details for CVE-2025-6936

Vulnerability Analysis

This SQL injection vulnerability (classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the /addpro.php file in the Simple Pizza Ordering System. The vulnerability stems from inadequate input validation and sanitization of the ID parameter, allowing attackers to inject malicious SQL statements that are then executed by the database engine.

SQL injection vulnerabilities of this nature can lead to unauthorized data access, data manipulation, and in severe cases, complete database server compromise. The network-accessible nature of this vulnerability means attackers can exploit it remotely without requiring local access to the target system.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize or parameterize user-supplied input in the ID parameter before incorporating it into SQL queries. The /addpro.php script likely constructs SQL queries using string concatenation or interpolation with unsanitized user input, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network by sending crafted HTTP requests to the /addpro.php endpoint. An attacker manipulates the ID parameter to include SQL injection payloads, which are then processed by the backend database without proper sanitization. This allows the attacker to execute arbitrary SQL commands, potentially extracting sensitive information such as user credentials, order details, and customer data stored in the pizza ordering system's database.

The vulnerability does not require authentication or user interaction, making it particularly dangerous for internet-facing deployments of this application. Attackers can leverage standard SQL injection techniques including UNION-based injection, boolean-based blind injection, or time-based blind injection to extract data or manipulate database contents.

Detection Methods for CVE-2025-6936

Indicators of Compromise

• Unusual database queries in application logs containing SQL keywords (UNION, SELECT, INSERT, DROP) in the ID parameter
• Abnormal HTTP requests to /addpro.php with encoded or malformed ID parameter values
• Database error messages appearing in web server logs indicating SQL syntax errors
• Unexpected data modifications or extractions from the pizza ordering system database

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the ID parameter
• Monitor application logs for requests containing SQL metacharacters and keywords in parameter values
• Deploy database activity monitoring to identify anomalous query patterns or unauthorized data access
• Set up intrusion detection system (IDS) signatures for SQL injection attack patterns against PHP applications

Monitoring Recommendations

• Enable detailed logging for all requests to /addpro.php and analyze for suspicious parameter values
• Configure database audit logging to track all queries executed against the application database
• Implement real-time alerting for database errors that may indicate attempted SQL injection attacks
• Monitor for unusual outbound data transfers that could indicate data exfiltration following successful exploitation

How to Mitigate CVE-2025-6936

Immediate Actions Required

• Restrict network access to the Simple Pizza Ordering System to trusted networks only until patching is complete
• Implement input validation and parameterized queries in the /addpro.php file to prevent SQL injection
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as an immediate defensive measure
• Review database logs for evidence of prior exploitation and assess potential data exposure

Patch Information

At the time of this publication, no official vendor patch has been identified for this vulnerability. Organizations using code-projects Simple Pizza Ordering System 1.0 should contact the vendor or consider implementing manual code fixes to address the SQL injection vulnerability. For additional technical details, refer to the GitHub Issue CVE Discussion and VulDB #314457.

Workarounds

• Implement server-side input validation to reject any ID parameter values containing SQL metacharacters
• Use prepared statements with parameterized queries to prevent SQL injection at the code level
• Deploy a reverse proxy or WAF configured to filter malicious SQL injection payloads
• Isolate the database server from direct internet access and implement least-privilege database user permissions
• Consider temporarily disabling or restricting access to the /addpro.php functionality until proper remediation is implemented
