CVE-2025-13291: Supplier Management System SQLi Flaw

CVE-2025-13291 Overview

A SQL Injection vulnerability has been identified in Campcodes Supplier Management System version 1.0. The vulnerability exists in the /manufacturer/confirm_order.php file, where the ID parameter is not properly sanitized before being used in database queries. This allows remote attackers to manipulate SQL queries by injecting malicious input through the vulnerable parameter, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive information from the database, bypass authentication mechanisms, or manipulate data within the Supplier Management System without requiring any authentication.

Affected Products

• Campcodes Supplier Management System 1.0

Technical Details for CVE-2025-13291

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs due to improper neutralization of special elements used in SQL commands. The /manufacturer/confirm_order.php file accepts an ID parameter that is directly incorporated into SQL queries without adequate input validation or parameterization. This classic injection vulnerability pattern also falls under the broader category of Injection flaws (CWE-74).

The vulnerability is remotely exploitable without authentication, meaning any attacker with network access to the application can attempt exploitation. The exploit has been publicly disclosed, increasing the risk profile for organizations running unpatched versions of this software.

Root Cause

The root cause is insufficient input sanitization in the confirm_order.php script. The application fails to properly validate, sanitize, or parameterize the ID argument before constructing and executing SQL queries. This allows user-supplied input to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely through network access to the vulnerable endpoint. An attacker would craft a malicious HTTP request targeting the /manufacturer/confirm_order.php file with a specially crafted ID parameter containing SQL injection payloads. Since no authentication is required to reach this endpoint, the attack surface is broad and easily accessible.

The attacker can manipulate the ID parameter to inject SQL statements that could:

• Extract sensitive data from the database (usernames, passwords, supplier information)
• Modify or delete database records
• Potentially escalate privileges within the application
• In some configurations, execute system commands if database permissions allow

Detection Methods for CVE-2025-13291

Indicators of Compromise

• Unusual or malformed requests to /manufacturer/confirm_order.php containing SQL syntax characters such as single quotes, double dashes, or UNION SELECT statements in the ID parameter
• Database error messages appearing in application logs indicating SQL syntax errors or unexpected query results
• Anomalous database queries in database audit logs showing injection patterns like ' OR 1=1--, UNION SELECT, or time-based blind injection attempts
• Unexpected data extraction or modification patterns in database transaction logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the confirm_order.php endpoint
• Implement application-level logging that captures all requests to the /manufacturer/ directory with full parameter values
• Configure database audit logging to identify suspicious query patterns including error-based injection attempts
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /manufacturer/confirm_order.php with varying ID parameter values
• Set up alerts for database errors that may indicate injection attempts, such as syntax errors or unexpected query behaviors
• Track failed authentication attempts and unusual data access patterns that could indicate post-exploitation activity
• Implement real-time monitoring for application response times that may indicate time-based blind SQL injection attempts

How to Mitigate CVE-2025-13291

Immediate Actions Required

• Restrict access to the /manufacturer/confirm_order.php file through web server configuration or network-level controls until a patch is available
• Implement Web Application Firewall rules to filter SQL injection patterns on the ID parameter
• Review database user privileges and apply principle of least privilege to limit potential damage from successful exploitation
• Audit access logs for signs of prior exploitation attempts

Patch Information

No official vendor patch has been identified in the available CVE data. Organizations using Campcodes Supplier Management System 1.0 should contact the vendor directly through CampCodes for security updates and patch availability. Additional vulnerability tracking information is available through the VulDB entry.

Workarounds

• Use parameterized queries or prepared statements if modifying the source code is possible
• Implement strict input validation on the ID parameter to accept only numeric values
• Deploy a reverse proxy with SQL injection filtering capabilities in front of the application
• Consider taking the application offline or restricting network access to trusted users only until remediation is complete

# Example Apache .htaccess configuration to restrict access
<Files "confirm_order.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
