CVE-2025-7933: Sales And Inventory System SQLi Flaw

CVE-2025-7933 Overview

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. This vulnerability exists in the /pages/settings_update.php file within the Setting Handler component, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete database contents, potentially compromising all inventory and sales data stored in the application.

Technical Details for CVE-2025-7933

Vulnerability Analysis

This SQL injection vulnerability occurs in the Setting Handler component of the Campcodes Sales and Inventory System. The vulnerable endpoint /pages/settings_update.php fails to properly sanitize or parameterize the ID argument before incorporating it into SQL queries. This allows an attacker to manipulate the SQL query structure by injecting malicious SQL statements through the ID parameter.

The vulnerability is network-accessible, requiring no authentication or user interaction for exploitation. An attacker can craft malicious HTTP requests containing SQL injection payloads in the ID parameter, which are then executed directly against the backend database. This could lead to unauthorized data access, data modification, or potential escalation to further system compromise depending on database privileges.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the /pages/settings_update.php file. The application directly concatenates user-supplied input from the ID parameter into SQL queries without proper sanitization or escaping, creating a classic SQL injection condition (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Attack Vector

The attack can be initiated remotely over the network. An attacker sends a crafted HTTP request to the /pages/settings_update.php endpoint with a malicious SQL payload in the ID parameter. Since no authentication is required and the vulnerability is straightforward to exploit, attackers can leverage common SQL injection techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection to extract database contents or manipulate data.

The exploit has been publicly disclosed, increasing the risk of widespread exploitation. For technical details regarding the vulnerability, refer to the GitHub CVE Issue Discussion and VulDB entry #317062.

Detection Methods for CVE-2025-7933

Indicators of Compromise

• HTTP requests to /pages/settings_update.php containing SQL syntax characters such as single quotes ('), double dashes (--), or UNION statements in the ID parameter
• Unusual database query patterns or errors in application logs indicating SQL syntax errors
• Unexpected data access patterns or bulk data extraction from the database
• Database audit logs showing queries with injection patterns such as ' OR 1=1-- or UNION SELECT statements

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter in requests to settings_update.php
• Implement database activity monitoring to identify anomalous query patterns or unauthorized data access
• Configure application logging to capture all requests to the Settings Handler component for forensic analysis
• Use intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

• Enable verbose logging on the web server for all requests to PHP endpoints, particularly /pages/settings_update.php
• Monitor database server logs for unusual query patterns, failed authentication attempts, or privilege escalation attempts
• Set up alerts for HTTP requests containing common SQL injection payloads or special characters in form parameters
• Regularly review access logs for suspicious activity patterns from unexpected IP addresses or geographic locations

How to Mitigate CVE-2025-7933

Immediate Actions Required

• Take the affected Campcodes Sales and Inventory System offline or restrict access to trusted networks only until a patch is applied
• Implement input validation on the ID parameter to accept only expected numeric values
• Deploy a web application firewall (WAF) with SQL injection protection rules as a temporary mitigation measure
• Review database access logs for signs of prior exploitation and assess potential data exposure

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations using Campcodes Sales and Inventory System 1.0 should monitor the Campcodes website for security updates and apply patches as soon as they become available. For additional vulnerability details, consult the VulDB CTIID #317062 entry.

Workarounds

• Implement prepared statements with parameterized queries in the vulnerable PHP code to prevent SQL injection
• Add server-side input validation to ensure the ID parameter contains only numeric values before processing
• Restrict network access to the application using firewall rules, limiting exposure to trusted IP ranges
• Consider disabling or removing the vulnerable Settings Handler functionality if it is not business-critical

# Example: Apache mod_security rule to block SQL injection attempts
# Add to Apache configuration or .htaccess
SecRule ARGS:ID "@detectSQLi" \
    "id:1001,\
    phase:2,\
    deny,\
    status:403,\
