CVE-2025-6315 Overview
A critical SQL injection vulnerability has been discovered in code-projects Online Shoe Store version 1.0. The vulnerability exists in the /cart2.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive customer data, modify shopping cart contents, or potentially compromise the entire database backend of the Online Shoe Store application.

Technical Details for CVE-2025-6315
Vulnerability Analysis
This SQL injection vulnerability stems from insufficient input validation in the shopping cart functionality of the Online Shoe Store application. The /cart2.php endpoint accepts an ID parameter that is directly incorporated into SQL queries without proper sanitization or parameterized query implementation. When user-supplied input is concatenated directly into SQL statements, attackers can craft malicious payloads that alter the intended query logic.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where untrusted input is not properly sanitized before being processed by an interpreter. The attack can be launched remotely over the network without requiring authentication, making it accessible to any attacker with network access to the vulnerable application.
Root Cause
The root cause of this vulnerability is the direct use of user-controlled input (the ID parameter) in SQL query construction without implementing proper input validation, sanitization, or parameterized queries. The application fails to treat user input as untrusted data, allowing SQL metacharacters and commands to be interpreted as part of the database query rather than as literal data values.
Attack Vector
The attack vector for this vulnerability is network-based, allowing remote exploitation. An attacker can manipulate the ID parameter in HTTP requests to /cart2.php to inject arbitrary SQL commands. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Typical attack scenarios include:
The vulnerability manifests when the ID parameter value is passed directly to SQL queries without sanitization. An attacker can append SQL syntax such as single quotes, UNION statements, or boolean-based conditions to extract data from the database, bypass authentication checks, or modify records. Since no authentication is required, any remote attacker can target this endpoint. See the GitHub Issue Report for additional technical details on the exploitation mechanism.
Detection Methods for CVE-2025-6315
Indicators of Compromise
- Unusual SQL error messages in web server logs originating from /cart2.php
- HTTP requests to /cart2.php containing SQL metacharacters such as single quotes, UNION keywords, or comment sequences in the ID parameter
- Database query logs showing unexpected SELECT, UNION, or data extraction queries from the cart functionality
- Anomalous data access patterns in application database tables, particularly user or payment information
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter
- Implement intrusion detection system (IDS) signatures for common SQL injection payloads targeting the /cart2.php endpoint
- Enable detailed logging on the web server and database to capture suspicious query patterns
- Monitor for unusual database query execution times or error rates that may indicate injection attempts
Monitoring Recommendations
- Review web application logs for requests containing SQL injection indicators in query parameters
- Set up alerts for HTTP 500 errors or database connection errors originating from /cart2.php
- Monitor database audit logs for unauthorized data access or extraction attempts
- Implement real-time alerting on WAF rule triggers related to SQL injection attacks
How to Mitigate CVE-2025-6315
Immediate Actions Required
- Remove or disable the /cart2.php file if the shopping cart functionality is not critical to operations
- Implement input validation to restrict the ID parameter to numeric values only
- Deploy a Web Application Firewall (WAF) to filter malicious SQL injection attempts
- Restrict database user permissions to limit the potential impact of successful exploitation
Patch Information
No official vendor patch has been released for this vulnerability at the time of publication. Organizations using code-projects Online Shoe Store 1.0 should implement the recommended workarounds and monitor Code Projects for security updates. Additional vulnerability details are available at VulDB #313315.
Workarounds
- Implement prepared statements or parameterized queries in the application code to prevent SQL injection
- Apply strict input validation to ensure the ID parameter accepts only integer values
- Use a WAF with SQL injection detection rules as a temporary protective measure
- Consider replacing the vulnerable component with a secure alternative if no patch becomes available
# Configuration example - Input validation for Apache mod_security
# Add to mod_security configuration to block SQL injection attempts
