CVE-2026-2164 Overview
A security flaw has been discovered in detronetdip E-commerce 1.0.0. This issue affects unknown processing of the file /seller/assets/backend/profile/addadhar.php. Performing a manipulation of the argument File results in unrestricted upload. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
Critical Impact
This unrestricted file upload vulnerability allows remote attackers to upload arbitrary files to the server, potentially leading to remote code execution if malicious PHP files or web shells are uploaded and executed on the target system.

Technical Details for CVE-2026-2164
Vulnerability Analysis
This vulnerability resides in the Aadhaar document upload functionality within the seller profile management section of the detronetdip E-commerce application. The vulnerable endpoint /seller/assets/backend/profile/addadhar.php fails to properly validate uploaded files, allowing attackers to upload files with arbitrary content and extensions.
The core issue stems from improper access control (CWE-284), where the application does not adequately restrict what types of files can be uploaded through the File parameter. This allows attackers to bypass intended security restrictions and upload executable content such as PHP web shells or other malicious scripts.
The vulnerability is remotely exploitable over the network without requiring authentication, making it particularly dangerous for internet-facing E-commerce installations. Once a malicious file is uploaded, an attacker can potentially execute arbitrary code on the server with the privileges of the web server process.
Root Cause
The root cause of this vulnerability is improper access control and missing input validation in the file upload handler. The addadhar.php script does not implement proper file type validation, extension filtering, or content verification before accepting and storing uploaded files. This allows any file type to be uploaded regardless of its content or intended use.
Attack Vector
The attack vector is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by:
- Crafting a malicious HTTP POST request to /seller/assets/backend/profile/addadhar.php
- Including a malicious file (such as a PHP web shell) in the File parameter
- Submitting the request to upload the malicious file to the server
- Accessing the uploaded file to trigger code execution
The vulnerability has been publicly disclosed with proof-of-concept code available in the GitHub PoC Repository. The issue was reported to the project maintainers via GitHub Issue #23, but no response has been received.
Detection Methods for CVE-2026-2164
Indicators of Compromise
- Unexpected files with executable extensions (.php, .phtml, .php5) appearing in upload directories
- Web server access logs showing requests to /seller/assets/backend/profile/addadhar.php followed by requests to unusual file paths
- Presence of web shells or backdoor scripts in the application's upload directories
- Unusual outbound network connections originating from the web server process
Detection Strategies
- Monitor HTTP POST requests to /seller/assets/backend/profile/addadhar.php for suspicious file uploads
- Implement file integrity monitoring on upload directories to detect unauthorized file creation
- Deploy web application firewall (WAF) rules to inspect file upload content and block executable file types
- Review web server logs for patterns indicative of web shell access or command execution attempts
Monitoring Recommendations
- Enable detailed logging for the E-commerce application's upload functionality
- Configure alerts for file creation events in web-accessible directories
- Monitor for unusual process spawning from the web server (e.g., shell commands, reverse connections)
- Implement network monitoring to detect command-and-control communications from compromised systems
How to Mitigate CVE-2026-2164
Immediate Actions Required
- Restrict access to /seller/assets/backend/profile/addadhar.php until a patch is available
- Implement web server configuration to deny execution of scripts in upload directories
- Review existing uploaded files for malicious content and remove any suspicious files
- Consider taking the affected E-commerce application offline if it handles sensitive data
Patch Information
No official patch is currently available from the vendor. The project maintainers were notified via GitHub Issue #23 but have not yet responded. Users should monitor the E-commerce GitHub repository for security updates.
Additional vulnerability details are available at VulDB #344866.
Workarounds
- Configure .htaccess or equivalent web server rules to prevent PHP execution in upload directories
- Implement server-side file type validation using MIME type checking and file content inspection
- Rename uploaded files to remove executable extensions and store originals outside the web root
- Deploy a reverse proxy or WAF to filter malicious upload attempts before they reach the application
# Apache configuration to prevent PHP execution in upload directories
# Add to .htaccess in the uploads directory
<FilesMatch "\.(php|phtml|php5|php7)$">
Require all denied
</FilesMatch>
# Alternative: Disable PHP engine entirely for upload directories
php_flag engine off
