CVE-2025-10436: Campcodes Sales System SQLi Vulnerability

CVE-2025-10436 Overview

A SQL injection vulnerability has been identified in Campcodes Computer Sales and Inventory System version 1.0. The vulnerability exists in the /pages/sup_searchfrm.php file when the action=edit parameter is used. By manipulating the ID argument, an attacker can inject malicious SQL commands, potentially compromising the integrity and confidentiality of the underlying database. This vulnerability can be exploited remotely without authentication, making it a significant security risk for organizations using this inventory management software.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive data from the database, potentially leading to full database compromise and unauthorized access to customer and inventory information.

Technical Details for CVE-2025-10436

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the supplier search functionality within the Campcodes Computer Sales and Inventory System. The application fails to properly sanitize user-supplied input passed through the ID parameter in the sup_searchfrm.php script before incorporating it into SQL queries.

The vulnerable endpoint processes edit actions for supplier records and directly concatenates the ID parameter value into database queries without adequate input validation or parameterized query usage. This allows attackers to inject arbitrary SQL statements that the database engine will execute with the same privileges as the application's database user.

According to the VulDB Entry #323870, proof-of-concept exploit code has been made publicly available, increasing the risk of exploitation in the wild.

Root Cause

The root cause of this vulnerability is improper input validation and the use of dynamic SQL query construction. The application directly incorporates user-controlled input from the ID parameter into SQL statements without implementing prepared statements, parameterized queries, or proper input sanitization mechanisms. This classic injection vulnerability pattern occurs when developers fail to treat all user input as potentially malicious.

Attack Vector

The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker constructs a malicious HTTP request to the vulnerable endpoint /pages/sup_searchfrm.php?action=edit with a specially crafted ID parameter containing SQL injection payloads.

The exploitation process involves appending SQL syntax to the ID parameter value. For example, an attacker might inject UNION-based payloads to extract data from other tables, or use boolean-based blind injection techniques to enumerate database contents character by character. Given the network-accessible nature of this vulnerability and the lack of authentication requirements, any attacker with network access to the application can attempt exploitation. Technical details and proof-of-concept information are available through the GitHub Issue for CVE.

Detection Methods for CVE-2025-10436

Indicators of Compromise

• Unusual or malformed requests to /pages/sup_searchfrm.php containing SQL syntax characters such as single quotes, semicolons, UNION keywords, or comment sequences
• Database error messages appearing in application logs or HTTP responses that reveal SQL query structure
• Unexpected database query patterns or elevated query execution times indicating injection attempts
• Authentication bypass events or unauthorized data access from accounts without proper privileges

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests targeting the sup_searchfrm.php endpoint
• Configure database activity monitoring to alert on anomalous query patterns, especially those containing UNION, SELECT, or comment syntax from web application connections
• Enable detailed logging for the vulnerable PHP script to capture all incoming request parameters
• Deploy intrusion detection system (IDS) signatures to identify SQL injection attack patterns in network traffic

Monitoring Recommendations

• Review web server access logs for requests to /pages/sup_searchfrm.php with suspicious ID parameter values
• Monitor database logs for failed or unusual SQL query execution events that may indicate injection attempts
• Set up alerts for any database errors logged by the application that could reveal injection probing

How to Mitigate CVE-2025-10436

Immediate Actions Required

• Restrict network access to the Campcodes Computer Sales and Inventory System to trusted IP addresses only using firewall rules
• Implement a Web Application Firewall with SQL injection protection rules in front of the application
• Disable or restrict access to the /pages/sup_searchfrm.php endpoint if supplier search functionality is not critical to operations
• Conduct a review of database user permissions to ensure the application uses least-privilege access

Patch Information

At the time of publication, no official patch from Campcodes has been identified for this vulnerability. Organizations should monitor the CampCodes website and the GitHub Issue for CVE for updates regarding security fixes. Consider reaching out to the vendor directly to request a security update addressing this SQL injection vulnerability.

Workarounds

• Implement input validation at the application level by modifying the sup_searchfrm.php file to accept only numeric values for the ID parameter
• Deploy a reverse proxy or WAF configured to sanitize or block requests containing SQL injection payloads
• Restrict database user permissions to read-only access where write operations are not required, limiting the impact of successful exploitation
• Consider taking the application offline or replacing it with a more secure alternative if critical data is at risk

# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule ARGS:ID "(?i)(union|select|insert|update|delete|drop|--|;)" \
    "id:100001,phase:2,deny,status:403,msg:'SQL Injection Attempt Blocked on sup_searchfrm.php'"
