CVE-2025-10563: Grocery Sales & Inventory System SQLi Flaw

CVE-2025-10563 Overview

A SQL Injection vulnerability has been identified in Campcodes Grocery Sales and Inventory System version 1.0. This vulnerability affects the /ajax.php?action=save_category endpoint, where improper handling of the ID argument allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to the underlying database.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to read, modify, or delete sensitive data from the database, potentially compromising customer information, inventory records, and financial data stored in the Grocery Sales and Inventory System.

Affected Products

• Campcodes Grocery Sales and Inventory System 1.0

Technical Details for CVE-2025-10563

Vulnerability Analysis

This SQL Injection vulnerability exists within the category management functionality of the Campcodes Grocery Sales and Inventory System. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries executed against the backend database. Specifically, the ID parameter passed to the /ajax.php?action=save_category endpoint is not validated or escaped, allowing an attacker to manipulate the SQL query structure.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The exploit has been publicly disclosed, increasing the risk of exploitation in the wild.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the save_category action handler. The application directly concatenates user-supplied input into SQL statements without sanitization, escaping, or the use of prepared statements. This fundamental coding error allows attackers to break out of the intended SQL query context and execute arbitrary SQL commands.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the vulnerable /ajax.php?action=save_category endpoint, injecting SQL payloads through the ID parameter.

The vulnerability allows for various SQL Injection techniques including:

• Union-based injection - Extracting data from other database tables by appending UNION SELECT statements
• Error-based injection - Leveraging database error messages to enumerate database structure
• Blind SQL injection - Inferring information through boolean conditions or time-based delays
• Stacked queries - Potentially executing multiple SQL statements to modify or delete data

Attackers can leverage this vulnerability to bypass authentication, extract sensitive customer and business data, modify inventory records, or potentially gain further access to the underlying server depending on database permissions. For technical details regarding exploitation, refer to the GitHub security issue and VulDB entry.

Detection Methods for CVE-2025-10563

Indicators of Compromise

• Unusual or malformed HTTP requests to /ajax.php?action=save_category containing SQL syntax characters such as single quotes, semicolons, or UNION keywords
• Database error messages appearing in web server logs or application responses indicating SQL syntax errors
• Unexpected database queries or operations in database audit logs, particularly those involving the category management tables
• Evidence of data exfiltration or unauthorized database access patterns in network traffic

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting the ajax.php endpoint
• Implement application-layer monitoring to identify requests containing common SQL Injection payloads in the ID parameter
• Enable database query logging and audit functionality to detect anomalous query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for SQL Injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /ajax.php?action=save_category with varying ID parameter values indicative of fuzzing or injection attempts
• Set up alerts for database errors related to malformed SQL queries originating from the web application
• Implement rate limiting and anomaly detection for the affected endpoint to identify automated exploitation attempts
• Review authentication and access logs for signs of privilege escalation following potential SQL Injection exploitation

How to Mitigate CVE-2025-10563

Immediate Actions Required

• Restrict network access to the Campcodes Grocery Sales and Inventory System to trusted IP addresses only until a patch is available
• Deploy a Web Application Firewall (WAF) with SQL Injection protection rules specifically targeting the /ajax.php endpoint
• Review and backup all database contents to ensure data recovery capability in case of compromise
• Monitor application and database logs closely for signs of exploitation attempts

Patch Information

As of the last NVD update on September 22, 2025, no official vendor patch has been released for this vulnerability. Organizations using Campcodes Grocery Sales and Inventory System 1.0 should monitor the vendor website and the GitHub security issue for updates. Consider contacting the vendor directly regarding remediation timelines.

Workarounds

• Implement input validation at the application level to sanitize the ID parameter, allowing only numeric values
• Use a reverse proxy or WAF to filter requests containing SQL Injection patterns before they reach the application
• If source code access is available, modify the vulnerable code to use prepared statements or parameterized queries instead of direct string concatenation
• Consider temporarily disabling the category save functionality if it is not business-critical until a proper fix is implemented
