CVE-2025-6317: Online Shoe Store SQL Injection Flaw

CVE-2025-6317 Overview

A critical SQL injection vulnerability has been identified in code-projects Online Shoe Store version 1.0. The vulnerability exists in the /admin/confirm.php file where the ID parameter is improperly sanitized, allowing attackers to manipulate database queries. This flaw enables remote attackers to inject malicious SQL statements through the vulnerable parameter, potentially leading to unauthorized data access, data manipulation, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive customer data, modify database records, or potentially gain unauthorized administrative access to the Online Shoe Store application.

Technical Details for CVE-2025-6317

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the administrative confirmation functionality of the Online Shoe Store application. The /admin/confirm.php endpoint accepts an ID parameter that is directly incorporated into SQL queries without proper sanitization or parameterized query implementation. This classic injection vector allows attackers to append arbitrary SQL commands to legitimate queries, potentially bypassing authentication controls and accessing or manipulating the underlying database.

The vulnerability is network-accessible, meaning attackers can exploit it remotely without requiring authentication or user interaction. The exploit has been publicly disclosed, increasing the risk of widespread exploitation attempts against vulnerable installations.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when handling the ID parameter in /admin/confirm.php. User-supplied input is concatenated directly into SQL statements, creating an injection point that attackers can leverage to execute arbitrary database commands.

Attack Vector

The attack can be initiated remotely over the network by sending specially crafted HTTP requests to the /admin/confirm.php endpoint. An attacker manipulates the ID parameter to include SQL metacharacters and injection payloads that alter the intended query logic.

The vulnerability can be exploited by appending SQL injection payloads to the ID parameter in requests to the administrative confirmation page. Attackers may use techniques such as UNION-based injection to extract data from other database tables, boolean-based blind injection to infer database contents, or time-based injection to confirm vulnerability presence. For detailed technical analysis and proof-of-concept information, refer to the GitHub Issue #3 and VulDB entry #313317.

Detection Methods for CVE-2025-6317

Indicators of Compromise

• Unusual SQL error messages in application logs referencing /admin/confirm.php
• HTTP requests to /admin/confirm.php containing SQL metacharacters such as single quotes, UNION statements, or comment sequences
• Unexpected database query patterns or execution times indicating injection attempts
• Access logs showing repeated requests to the confirmation endpoint with varying ID parameter values

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter
• Implement application-level logging to capture and alert on malformed or suspicious ID parameter inputs
• Monitor database query logs for anomalous queries originating from the confirmation functionality
• Use intrusion detection systems (IDS) with SQL injection signature rules targeting the vulnerable endpoint

Monitoring Recommendations

• Enable detailed access logging for the /admin/ directory and monitor for suspicious request patterns
• Configure database activity monitoring to detect unauthorized data extraction or modification attempts
• Set up alerting for increased error rates or unusual response times from the confirmation endpoint
• Review authentication logs for potential privilege escalation following SQL injection exploitation

How to Mitigate CVE-2025-6317

Immediate Actions Required

• Restrict network access to the /admin/confirm.php endpoint using IP allowlisting or VPN requirements
• Deploy WAF rules to block requests containing SQL injection payloads in the ID parameter
• Consider temporarily disabling the vulnerable confirmation functionality until a patch is applied
• Audit database accounts used by the application and apply least-privilege principles

Patch Information

No vendor patch information is currently available for this vulnerability. Users of code-projects Online Shoe Store should monitor the Code Projects website for security updates. Given the lack of official remediation, organizations should implement the workarounds and detection strategies outlined below.

Workarounds

• Implement server-side input validation to ensure the ID parameter contains only expected numeric values
• Modify the application code to use parameterized queries (prepared statements) instead of string concatenation
• Add Web Application Firewall rules to filter malicious SQL injection payloads targeting the vulnerable endpoint
• Restrict access to administrative functions using network segmentation and strong authentication controls

The following PHP code pattern demonstrates proper parameterized query implementation that should replace vulnerable string concatenation:

# Secure implementation using prepared statements
$stmt = $pdo->prepare("SELECT * FROM orders WHERE id = :id");
$stmt->execute(['id' => $_GET['ID']]);
$result = $stmt->fetch();
