CVE-2025-10425: 1000projects Student System RCE Flaw

CVE-2025-10425 Overview

A critical unrestricted file upload vulnerability has been identified in 1000projects Online Student Project Report Submission and Evaluation System version 1.0. The vulnerability exists in the file /admin/controller/student_controller.php, where improper handling of the new_image argument allows attackers to upload arbitrary files without proper validation. This flaw can be exploited remotely and may lead to remote code execution if malicious files such as web shells are uploaded to the server.

Critical Impact

Remote attackers can exploit this unrestricted file upload vulnerability to upload malicious files, potentially leading to complete server compromise, data theft, or further attacks on the underlying infrastructure.

Technical Details for CVE-2025-10425

Vulnerability Analysis

This vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) and CWE-284 (Improper Access Control). The vulnerable component resides in the administrative controller functionality, specifically within the student controller PHP file. The application fails to properly validate file types, extensions, and content when processing uploads through the new_image parameter.

The attack can be initiated remotely over the network without requiring authentication or user interaction. When exploited, an attacker gains the ability to upload files of any type to the web server, including executable scripts such as PHP web shells. Once uploaded, these malicious files can be accessed directly via the web server, enabling arbitrary code execution within the context of the web application.

Root Cause

The root cause of this vulnerability is the absence of proper file validation mechanisms in the /admin/controller/student_controller.php file. The application does not implement adequate checks for:

• File type validation (MIME type verification)
• File extension whitelisting
• File content inspection
• Upload directory restrictions

This allows attackers to bypass any intended restrictions and upload dangerous file types that can be executed by the web server.

Attack Vector

The vulnerability is exploitable via network-based attacks targeting the file upload functionality. An attacker can craft a malicious HTTP request to the vulnerable endpoint, manipulating the new_image parameter to upload a web shell or other malicious payload.

The attack flow typically involves:

1. Identifying the vulnerable upload endpoint at /admin/controller/student_controller.php
2. Crafting a multipart form-data request with a malicious file (e.g., PHP web shell)
3. Submitting the request to the vulnerable server
4. Accessing the uploaded malicious file to execute commands

Technical details and proof-of-concept information are available in the GitHub Issue Report and VulDB entry #323859.

Detection Methods for CVE-2025-10425

Indicators of Compromise

• Unexpected PHP, PHTML, or other executable files appearing in upload directories
• Web server logs showing requests to newly created files in upload paths
• Suspicious POST requests to /admin/controller/student_controller.php with unusual file content
• Outbound connections from the web server to unknown external hosts

Detection Strategies

• Monitor file system changes in web-accessible upload directories for newly created executable files
• Implement web application firewall (WAF) rules to inspect multipart uploads for malicious content
• Review web server access logs for unusual patterns targeting the vulnerable endpoint
• Deploy endpoint detection and response (EDR) solutions to identify web shell behaviors

Monitoring Recommendations

• Enable detailed logging for the /admin/controller/ directory and monitor for anomalous activity
• Configure alerts for new file creation events in directories accessible via the web server
• Implement integrity monitoring on critical application directories to detect unauthorized changes
• Monitor for command execution patterns typical of web shell activity (whoami, id, pwd, etc.)

How to Mitigate CVE-2025-10425

Immediate Actions Required

• Restrict access to the /admin/controller/student_controller.php endpoint until a patch is applied
• Implement strict file upload validation including extension whitelisting and MIME type verification
• Configure the web server to prevent execution of uploaded files (disable PHP execution in upload directories)
• Review existing uploaded files for potentially malicious content and remove suspicious files
• Consider temporarily disabling the file upload functionality if not critical to operations

Patch Information

At the time of publication, no official patch from 1000projects has been identified for this vulnerability. Organizations using this software should monitor the vendor's communications for security updates. In the absence of an official fix, implementing the workarounds and mitigations described below is strongly recommended.

For additional technical details and ongoing updates, refer to VulDB #323859.

Workarounds

• Configure .htaccess or web server rules to prevent script execution in upload directories
• Implement server-side file type validation by inspecting file headers and magic bytes
• Rename uploaded files to remove executable extensions and store them outside the web root
• Apply network-level access controls to restrict who can reach administrative endpoints
• Deploy a web application firewall with rules to block malicious file uploads

# Apache configuration to disable PHP execution in uploads directory
# Add to .htaccess in the uploads folder or to Apache config
<Directory "/var/www/html/uploads">
    php_admin_flag engine Off
    <FilesMatch "\.(php|phtml|php3|php4|php5|phps)$">
        Require all denied
    </FilesMatch>
</Directory>
