CVE-2025-10413: Grocery Sales Inventory System SQLi Flaw

CVE-2025-10413 Overview

A SQL injection vulnerability has been identified in Campcodes Grocery Sales and Inventory System version 1.0. The vulnerability exists in the /ajax.php?action=delete_customer endpoint, where improper sanitization of the ID argument allows attackers to inject malicious SQL statements. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete data from the underlying database, potentially compromising customer information and business-critical inventory data.

Technical Details for CVE-2025-10413

Vulnerability Analysis

This SQL injection vulnerability affects the customer deletion functionality within the Campcodes Grocery Sales and Inventory System. The application fails to properly validate and sanitize user-supplied input in the ID parameter before incorporating it into SQL queries. When a user or attacker sends a request to the /ajax.php?action=delete_customer endpoint, the ID parameter value is directly concatenated into the SQL query without proper parameterization or escaping.

The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). This categorization indicates both the specific SQL injection weakness and the broader injection vulnerability class.

The exploit has been publicly disclosed, increasing the risk of active exploitation against vulnerable installations. Organizations using this software should treat remediation as a priority.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and the use of unsanitized user input in SQL query construction. The ID parameter passed to the delete_customer action in /ajax.php is directly incorporated into database queries without being properly escaped, parameterized, or validated as an integer value. This allows attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack can be executed remotely over the network without requiring authentication or user interaction. An attacker can craft a malicious HTTP request to the vulnerable endpoint, manipulating the ID parameter to include SQL injection payloads. Successful exploitation could allow the attacker to:

• Extract sensitive data from the database including customer records and inventory information
• Modify or delete existing database records
• Bypass authentication mechanisms
• Potentially execute administrative operations on the database server
• In some configurations, read or write files on the underlying system

The vulnerability is accessible via standard HTTP requests, making it trivially exploitable with common tools and techniques. The publicly disclosed nature of this exploit means that proof-of-concept code may be available to attackers. For technical details, refer to the GitHub Issue Discussion and VulDB entry #323847.

Detection Methods for CVE-2025-10413

Indicators of Compromise

• HTTP requests to /ajax.php?action=delete_customer containing SQL syntax in the ID parameter (e.g., single quotes, UNION statements, OR conditions)
• Unusual database query patterns or errors in application logs
• Unexpected data modifications or deletions in customer records
• Database error messages exposed in HTTP responses indicating query manipulation attempts

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in request parameters
• Monitor application logs for requests to /ajax.php endpoints with suspicious ID parameter values
• Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for all requests to /ajax.php and related endpoints
• Configure alerts for database errors that may indicate SQL injection attempts
• Monitor for unusual data access patterns, especially bulk data extraction from customer tables
• Review access logs regularly for repeated requests to the vulnerable endpoint with varying parameter values

How to Mitigate CVE-2025-10413

Immediate Actions Required

• Restrict access to the /ajax.php endpoint through network-level controls or authentication requirements
• Implement a web application firewall (WAF) to filter malicious SQL injection payloads
• Consider taking the application offline if it processes sensitive data until a patch is available
• Audit database logs for any signs of past exploitation

Patch Information

At the time of publication, no official patch has been released by Campcodes for this vulnerability. Organizations should monitor the Campcodes website for security updates. In the absence of an official fix, implementing the workarounds below is strongly recommended.

Workarounds

• Apply input validation to ensure the ID parameter only accepts numeric integer values
• Implement prepared statements or parameterized queries in the application code to prevent SQL injection
• Deploy a web application firewall configured to block SQL injection attack patterns
• Restrict network access to the application to trusted IP addresses only
• Consider implementing additional authentication requirements for administrative AJAX endpoints

# Example: Block suspicious requests at the web server level (Apache .htaccess)
# Add to .htaccess in the web root directory
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|concat|char|hex|unhex|load_file|into\s+outfile) [NC]
RewriteRule ^ajax\.php$ - [F,L]
