CVE-2025-10831: Campcodes Computer Sales System SQLi Flaw

CVE-2025-10831 Overview

A SQL injection vulnerability has been identified in Campcodes Computer Sales and Inventory System version 1.0. The vulnerability exists within the /pages/pro_edit1.php file, where improper handling of the prodcode argument allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive data in the underlying database without authentication. The exploit has been publicly disclosed, increasing the risk of widespread exploitation.

Technical Details for CVE-2025-10831

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the product editing functionality of the Campcodes Computer Sales and Inventory System. The vulnerable endpoint /pages/pro_edit1.php accepts a prodcode parameter that is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to craft malicious input that breaks out of the intended query structure and executes arbitrary SQL commands against the backend database.

The attack is network-accessible, meaning any remote attacker who can reach the vulnerable web application can attempt exploitation. The vulnerability can lead to unauthorized read access to sensitive inventory and sales data, potential modification of product records, and in severe cases, complete database compromise.

Root Cause

The root cause of this vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The application fails to properly sanitize user-supplied input in the prodcode parameter before incorporating it into SQL queries. This lack of input validation allows special SQL characters and commands to be interpreted by the database engine rather than being treated as literal data.

Attack Vector

The vulnerability is exploitable remotely over the network. An attacker can target the /pages/pro_edit1.php endpoint by manipulating the prodcode parameter in HTTP requests. Since no authentication or special privileges appear to be required, the attack surface is significant.

The attacker constructs a malicious prodcode value containing SQL syntax elements that escape the intended query context. This allows the injection of additional SQL statements that can extract sensitive data, modify existing records, or perform other malicious database operations. The exploit has been publicly disclosed, making it accessible to a wide range of threat actors.

Detection Methods for CVE-2025-10831

Indicators of Compromise

HTTP requests to /pages/pro_edit1.php containing SQL-specific characters such as single quotes, semicolons, or SQL keywords (UNION, SELECT, DROP) in the prodcode parameter
Unexpected database errors or SQL syntax errors appearing in application logs
Anomalous database query patterns or unusually high database activity from the web application
Evidence of data exfiltration or unauthorized data modifications in database audit logs

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the prodcode parameter
Enable detailed logging on the web application to capture all requests to /pages/pro_edit1.php and monitor for suspicious input patterns
Configure database query monitoring to alert on unusual query structures or failed query attempts
Deploy intrusion detection systems (IDS) with signatures specific to SQL injection attack patterns

Monitoring Recommendations

Regularly review web server access logs for requests containing encoded or obfuscated SQL injection payloads
Monitor database performance metrics for anomalous query execution times that may indicate exploitation attempts
Implement real-time alerting for any database access errors originating from the affected PHP file
Conduct periodic security assessments of the application to identify similar injection points

How to Mitigate CVE-2025-10831

Immediate Actions Required

Remove or restrict access to the vulnerable /pages/pro_edit1.php endpoint until a patch is applied
Implement input validation to sanitize the prodcode parameter, rejecting any non-alphanumeric characters
Deploy a Web Application Firewall (WAF) with SQL injection protection rules as an immediate defensive measure
Review database user permissions to ensure the application uses least-privilege database accounts

Patch Information

No official vendor patch has been released at the time of this publication. Organizations using Campcodes Computer Sales and Inventory System 1.0 should monitor the CampCodes official website for security updates. Additional technical details can be found in the GitHub CVE Issue Discussion and the VulDB entry.

Workarounds

Implement prepared statements with parameterized queries in the pro_edit1.php file to prevent SQL injection
Add server-side input validation that strictly validates the prodcode parameter format before processing
Restrict network access to the affected endpoint using firewall rules or .htaccess configurations
Consider temporarily disabling the product editing functionality if it is not business-critical

bash

# Example .htaccess restriction for the vulnerable endpoint
<Files "pro_edit1.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
