CVE-2025-10435: Campcodes Inventory System SQLi Flaw

CVE-2025-10435 Overview

A SQL injection vulnerability has been discovered in Campcodes Computer Sales and Inventory System version 1.0. The vulnerability exists in the /pages/cust_edit1.php file, where improper handling of the ID parameter 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 access, modify, or delete database contents without authentication. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Technical Details for CVE-2025-10435

Vulnerability Analysis

This SQL injection vulnerability affects the customer editing functionality within the Campcodes Computer Sales and Inventory System. The vulnerable endpoint /pages/cust_edit1.php fails to properly sanitize the ID parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are executed by the underlying database engine.

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 network-accessible attack vector with no authentication requirements makes this vulnerability particularly concerning for organizations with internet-exposed instances of this software.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries in the cust_edit1.php file. The application directly incorporates user-supplied input from the ID parameter into SQL queries without sanitization or the use of prepared statements. This allows specially crafted input containing SQL syntax to modify the intended query logic.

Attack Vector

The attack can be performed remotely over the network. An unauthenticated attacker can manipulate the ID parameter in requests to the /pages/cust_edit1.php endpoint to inject malicious SQL statements. By crafting specific payloads, attackers can extract sensitive data from the database, modify existing records, delete data, or potentially execute administrative operations depending on the database user privileges.

The vulnerability requires no user interaction and can be exploited with low complexity. Typical SQL injection techniques such as UNION-based attacks, blind SQL injection, or time-based attacks may be applicable depending on the application's response behavior.

Detection Methods for CVE-2025-10435

Indicators of Compromise

• Unusual or malformed requests to /pages/cust_edit1.php containing SQL syntax in the ID parameter
• Database error messages appearing in application logs indicating SQL syntax errors
• Unexpected database queries or operations logged by database monitoring tools
• Access patterns showing repeated requests to the vulnerable endpoint with varying ID parameter values

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the ID parameter
• Monitor HTTP access logs for requests to /pages/cust_edit1.php containing suspicious characters such as single quotes, double dashes, or SQL keywords
• 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 verbose logging for the web application to capture all request parameters
• Configure database audit logging to track all queries executed against sensitive tables
• Set up alerts for failed SQL queries that may indicate injection attempts
• Monitor for unusual data exfiltration patterns or large result sets being returned

How to Mitigate CVE-2025-10435

Immediate Actions Required

• Restrict network access to the Campcodes Computer Sales and Inventory System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• If possible, disable or restrict access to the /pages/cust_edit1.php endpoint until a patch is available
• Review database user permissions and apply the principle of least privilege

Patch Information

No official vendor patch has been identified for this vulnerability at the time of publication. Organizations should monitor the Campcodes website for security updates. For additional technical details about this vulnerability, refer to the GitHub Issue on CVE and VulDB entry #323869.

Workarounds

• Deploy a reverse proxy or WAF in front of the application to filter malicious SQL injection attempts
• Modify the application code to use parameterized queries or prepared statements for the ID parameter if source code access is available
• Implement input validation to ensure the ID parameter only accepts numeric values
• Consider taking the system offline or limiting access until a proper fix can be applied
• Regularly backup the database to enable recovery in case of data manipulation or deletion

# Example: Restrict access to vulnerable endpoint using Apache .htaccess
# Add to /pages/.htaccess or main Apache configuration
<Files "cust_edit1.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
