CVE-2025-12336: Retro Basketball Shoes Store SQLi Flaw

CVE-2025-12336 Overview

A SQL Injection vulnerability has been identified in Campcodes Retro Basketball Shoes Online Store version 1.0. The vulnerability exists in the /admin/admin_index.php file where improper sanitization of the Username argument allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially allowing unauthorized access to the underlying database and compromising sensitive data.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially gain unauthorized administrative access to the online store application.

Technical Details for CVE-2025-12336

Vulnerability Analysis

This vulnerability is a classic SQL Injection flaw (CWE-89) that also falls under the broader category of Injection attacks (CWE-74). The affected component is the administrative login functionality located at /admin/admin_index.php. The application fails to properly sanitize user-supplied input in the Username parameter before incorporating it into SQL queries. This lack of input validation creates an opportunity for attackers to inject arbitrary SQL commands that will be executed by the database server.

The vulnerability is remotely exploitable without requiring any authentication or user interaction. An attacker can craft malicious input containing SQL syntax that, when processed by the application, modifies the intended query logic. This could result in authentication bypass, data exfiltration, or database manipulation.

Root Cause

The root cause of CVE-2025-12336 is insufficient input validation and the failure to use parameterized queries or prepared statements in the PHP application. The Username parameter value is directly concatenated into SQL queries without proper escaping or sanitization. This allows special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack vector is network-based, allowing remote exploitation. An attacker can target the /admin/admin_index.php endpoint by submitting a crafted Username parameter containing SQL injection payloads. Common attack techniques include:

Authentication bypass using payloads like ' OR '1'='1 to manipulate login logic
UNION-based injection to extract data from other database tables
Time-based blind SQL injection to enumerate database contents when direct output is not visible
Stacked queries (if supported) to execute additional malicious SQL statements

The exploit has been publicly disclosed, increasing the risk of widespread exploitation against unpatched systems. Technical details are available through the GitHub CVE Issue Discussion and VulDB #330123.

Detection Methods for CVE-2025-12336

Indicators of Compromise

Unusual or malformed requests to /admin/admin_index.php containing SQL syntax characters such as single quotes, double dashes, semicolons, or UNION keywords
Database error messages appearing in application logs or HTTP responses indicating query failures
Unexpected database queries or access patterns in database audit logs
Evidence of data exfiltration or unauthorized administrative access

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the Username parameter
Monitor web server access logs for suspicious requests to the /admin/admin_index.php endpoint
Enable database query logging and alert on anomalous query patterns or syntax errors
Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

Configure real-time alerting for any requests containing SQL metacharacters directed at authentication endpoints
Establish baseline metrics for normal administrative login attempts and alert on deviations
Review database access logs regularly for signs of unauthorized data access or privilege escalation
Monitor for new user accounts or privilege changes that could indicate post-exploitation activity

How to Mitigate CVE-2025-12336

Immediate Actions Required

Restrict access to the /admin/admin_index.php endpoint using IP allowlisting or VPN requirements
Deploy a Web Application Firewall (WAF) with SQL injection protection rules
Consider taking the administrative interface offline until a patch is available or the code can be remediated
Review database logs for any signs of previous exploitation attempts

Patch Information

As of the last NVD update on 2025-11-03, no official vendor patch has been released for this vulnerability. Organizations using Campcodes Retro Basketball Shoes Online Store 1.0 should monitor the CampCodes website for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.

For additional technical details and vulnerability tracking, refer to:

Workarounds

Implement input validation at the application level to reject any Username input containing SQL metacharacters
Modify the vulnerable code to use prepared statements or parameterized queries instead of string concatenation
Add a reverse proxy or WAF in front of the application to filter malicious input
Implement network-level access controls to limit who can reach the administrative interface
Consider using an alternative e-commerce platform until the vulnerability is properly addressed

# Example: Apache .htaccess to restrict admin access by IP
<Files "admin_index.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
