CVE-2025-6316: Online Shoe Store SQLi Vulnerability

CVE-2025-6316 Overview

A critical SQL injection vulnerability has been identified in code-projects Online Shoe Store version 1.0. The vulnerability exists in the /admin/admin_running.php file, where the qty parameter is susceptible to SQL injection attacks. This flaw allows remote attackers to manipulate database queries by injecting malicious SQL code through the quantity parameter, potentially leading to unauthorized data access, modification, or deletion. The exploit has been publicly disclosed and may be actively used in the wild.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive database information including customer data, payment details, and administrative credentials without authentication.

Technical Details for CVE-2025-6316

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the administrative functionality of the Online Shoe Store application. The vulnerable endpoint /admin/admin_running.php fails to properly sanitize user-supplied input in the qty parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are executed by the database server with the application's privileges.

The vulnerability can be exploited remotely over the network without requiring any authentication or user interaction. An attacker can manipulate the qty parameter to execute arbitrary SQL statements, potentially extracting sensitive information from the database, modifying data integrity, or disrupting application availability.

Root Cause

The root cause of this vulnerability is the absence of proper input sanitization and parameterized queries in the /admin/admin_running.php file. The application directly incorporates user-supplied data from the qty parameter into SQL statements without escaping special characters or using prepared statements. This implementation violates secure coding practices and allows attackers to break out of the intended SQL query structure.

Attack Vector

The attack vector is network-based, meaning attackers can exploit this vulnerability remotely without physical access to the target system. The attack requires no authentication or special privileges, and no user interaction is necessary for successful exploitation. An attacker simply needs to send a crafted HTTP request to the vulnerable endpoint with a malicious payload in the qty parameter.

The vulnerability allows for classic SQL injection techniques, where the attacker can append or modify SQL commands by inserting special characters such as single quotes, semicolons, or SQL keywords. This can enable union-based injection for data extraction, boolean-based blind injection for information inference, or time-based blind injection when direct output is not available.

Detection Methods for CVE-2025-6316

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or HTTP responses from /admin/admin_running.php
• Anomalous database queries containing SQL keywords (UNION, SELECT, INSERT, DELETE) in the qty parameter
• Failed login attempts followed by successful authentication without valid credentials
• Unexpected data extraction or modification patterns in database audit logs

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in the qty parameter
• Monitor HTTP request logs for suspicious characters and SQL keywords in form parameters
• Deploy database activity monitoring to identify unauthorized query patterns or data access
• Use intrusion detection systems (IDS) with signatures for common SQL injection payloads

Monitoring Recommendations

• Enable verbose logging for the /admin/admin_running.php endpoint and review logs for injection attempts
• Configure database audit logging to track all queries executed against sensitive tables
• Set up alerts for unusual database activity such as bulk data exports or schema modifications
• Monitor network traffic for large data exfiltration from database servers

How to Mitigate CVE-2025-6316

Immediate Actions Required

• Restrict access to the /admin/admin_running.php endpoint using IP whitelisting or VPN requirements
• Implement a web application firewall (WAF) to filter SQL injection attempts
• Review and audit all administrative endpoints for similar input validation issues
• Consider taking the application offline until a patch can be applied

Patch Information

As of the last update on 2025-06-26, no official vendor patch has been released for this vulnerability. Users of code-projects Online Shoe Store 1.0 should monitor the Code Projects website for security updates. The vulnerability details have been documented in VulDB #313316 and a related GitHub issue discussion provides additional technical information.

Workarounds

• Implement server-side input validation to sanitize the qty parameter, allowing only numeric values
• Use prepared statements or parameterized queries in the PHP code to prevent SQL injection
• Deploy a web application firewall (WAF) with SQL injection detection rules as a protective layer
• Limit database user privileges for the application to minimum required permissions (principle of least privilege)
• Enable database query logging and implement real-time monitoring for suspicious activity
