CVE-2025-6312: Campcodes Sales And Inventory SQLI Flaw

CVE-2025-6312 Overview

A critical SQL Injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The vulnerability exists in the /pages/cash_transaction.php file, where improper handling of the cid parameter allows attackers to inject malicious SQL commands. 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 sensitive business data, modify inventory records, or potentially gain unauthorized access to the underlying database server through the vulnerable cid parameter in the cash transaction functionality.

Technical Details for CVE-2025-6312

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) represents a classic injection flaw where user-supplied input is incorporated into SQL queries without proper sanitization or parameterization. The vulnerable endpoint /pages/cash_transaction.php accepts a cid parameter that is directly concatenated into database queries, allowing attackers to manipulate the query logic.

The vulnerability is classified under both CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and CWE-89 (SQL Injection), indicating that input validation and output encoding controls are absent from the affected code path. This allows malicious actors to craft specially formatted input that breaks out of the intended query context and executes arbitrary SQL statements.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the cash_transaction.php file. The cid parameter, which likely represents a customer or cash transaction identifier, is directly interpolated into SQL statements without sanitization. This design flaw allows special SQL characters and commands to be interpreted by the database engine rather than being treated as literal data values.

Attack Vector

The attack can be initiated remotely over the network. An unauthenticated attacker can send malicious HTTP requests to the /pages/cash_transaction.php endpoint with a crafted cid parameter containing SQL injection payloads. Common exploitation techniques include:

• Using UNION-based injection to extract data from other database tables
• Employing boolean-based blind injection to enumerate database contents
• Leveraging time-based blind injection when error messages are suppressed
• Potentially executing stacked queries to modify or delete data

The exploit has been publicly disclosed, increasing the risk of active exploitation. Technical details are available through the GitHub Issue Report and VulDB #313312.

Detection Methods for CVE-2025-6312

Indicators of Compromise

• HTTP requests to /pages/cash_transaction.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords in the cid parameter
• Database error messages appearing in application logs related to cash transaction queries
• Unusual database query patterns or execution times indicating blind SQL injection attempts
• Unexpected data access or modifications to transaction and inventory records

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the cid parameter
• Implement application-level logging for all requests to cash_transaction.php with parameter inspection
• Monitor database logs for anomalous queries originating from the web application context
• Use intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

• Enable detailed access logging for the /pages/ directory and review logs for suspicious parameter values
• Configure database query auditing to detect unauthorized SELECT, INSERT, UPDATE, or DELETE operations
• Set up alerts for multiple failed or malformed requests to the cash transaction endpoint
• Monitor for data exfiltration patterns in network traffic originating from the database server

How to Mitigate CVE-2025-6312

Immediate Actions Required

• Restrict network access to the Campcodes Sales and Inventory System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Review and audit all database accounts used by the application, applying principle of least privilege
• Back up database contents and monitor for signs of compromise

Patch Information

No official vendor patch has been identified for this vulnerability at the time of publication. Organizations using Campcodes Sales and Inventory System 1.0 should monitor the CampCodes official website for security updates. Additional vulnerability tracking information is available through VulDB CTI ID #313312 and the VulDB Submission #595930.

Workarounds

• Implement input validation to allow only numeric values for the cid parameter before processing
• Deploy a reverse proxy with request filtering capabilities to sanitize incoming parameters
• Consider disabling or restricting access to the cash_transaction.php functionality until a patch is available
• Modify application code to use prepared statements or parameterized queries if source code access is available

# Example: Apache mod_rewrite rule to block SQL injection attempts
# Add to .htaccess in the application root directory
RewriteEngine On
RewriteCond %{QUERY_STRING} (\%27)|(\')|(\-\-)|(\%23)|(#) [NC,OR]
RewriteCond %{QUERY_STRING} (union.*select) [NC,OR]
RewriteCond %{QUERY_STRING} (select.*from) [NC]
RewriteRule ^pages/cash_transaction\.php - [F,L]
