CVE-2025-7470 Overview
A critical unrestricted file upload vulnerability has been identified in Campcodes Sales and Inventory System 1.0. The vulnerability exists in the /pages/product_add.php file, where improper validation of the image parameter allows attackers to upload malicious files without proper restrictions. This flaw can be exploited remotely without authentication, potentially enabling attackers to execute arbitrary code on the affected server.
Critical Impact
Remote attackers can upload malicious files through the product image upload functionality, potentially leading to remote code execution and complete system compromise.

Technical Details for CVE-2025-7470
Vulnerability Analysis
This vulnerability is classified as an unrestricted file upload issue (CWE-434) combined with improper access control (CWE-284). The affected component, /pages/product_add.php, processes file uploads for product images without implementing adequate security controls. The application fails to properly validate file types, extensions, or content before accepting and storing uploaded files on the server.
The network-accessible attack vector means that any remote attacker can target vulnerable instances directly over the internet. No user interaction is required for exploitation, and the attack complexity is low, making this vulnerability particularly dangerous for publicly exposed installations.
Root Cause
The root cause lies in the insufficient input validation within the file upload handling mechanism. The image parameter in the product addition functionality does not enforce proper file type restrictions, MIME type validation, or content inspection. This allows attackers to bypass intended restrictions by uploading files with malicious content disguised as legitimate image files, or by directly uploading executable server-side scripts such as PHP webshells.
Attack Vector
An attacker can exploit this vulnerability by crafting a malicious HTTP POST request to the /pages/product_add.php endpoint. The attack involves manipulating the image parameter to upload a file containing malicious code (such as a PHP webshell) instead of a legitimate image file. Once uploaded, the attacker can access the uploaded file directly through the web server to execute arbitrary commands on the underlying system.
The exploitation process typically involves:
- Identifying a vulnerable Campcodes Sales and Inventory System instance
- Crafting a multipart form request with a malicious PHP file
- Submitting the request to the /pages/product_add.php endpoint
- Locating the uploaded file in the web-accessible upload directory
- Executing the malicious payload by accessing the uploaded file
Technical details and proof-of-concept information are available in the GitHub CVE Issue and the VulDB entry.
Detection Methods for CVE-2025-7470
Indicators of Compromise
- Unexpected file uploads in the product image upload directory with executable extensions (.php, .phtml, .php5)
- Web server access logs showing requests to unusual files in upload directories
- Presence of webshell signatures or encoded PHP code in uploaded files
- Unauthorized process execution originating from the web server context
Detection Strategies
- Monitor web application logs for POST requests to /pages/product_add.php with suspicious file extensions
- Implement file integrity monitoring on upload directories to detect unauthorized file modifications
- Deploy web application firewall (WAF) rules to detect and block file upload attacks
- Review uploaded files for executable content or known webshell patterns
Monitoring Recommendations
- Enable detailed logging for all file upload operations in the application
- Configure alerts for new file creation events in web-accessible upload directories
- Monitor for outbound connections from the web server that may indicate webshell activity
- Implement regular security scans to identify any uploaded malicious files
How to Mitigate CVE-2025-7470
Immediate Actions Required
- Restrict network access to the Campcodes Sales and Inventory System to trusted IP addresses only
- Implement web application firewall (WAF) rules to filter malicious file upload attempts
- Remove or rename the /pages/product_add.php file if product addition functionality is not required
- Review and remove any suspicious files in the upload directories
Patch Information
No vendor patch has been officially announced for this vulnerability at the time of publication. Organizations should monitor the Campcodes website for security updates and patches. Additional vulnerability information is available through VulDB.
Workarounds
- Implement server-side file type validation that checks both file extension and MIME type
- Configure the web server to deny execution of scripts in upload directories using .htaccess or server configuration
- Rename uploaded files to randomized names without preserving the original extension
- Store uploaded files outside the web root directory and serve them through a controlled handler
# Apache configuration to prevent script execution in uploads directory
<Directory /var/www/html/uploads>
php_admin_flag engine off
<FilesMatch "\.ph(p[345]?|tml)$">
