CVE-2025-10447: Campcodes Job Finder System RCE Flaw

CVE-2025-10447 Overview

A critical unrestricted file upload vulnerability has been identified in Campcodes Online Job Finder System version 1.0. The vulnerability exists in the /eris/applicationform.php file, where manipulation of the picture argument allows attackers to upload arbitrary files without proper validation. This flaw can be exploited remotely without authentication, potentially enabling attackers to upload malicious scripts that could lead to remote code execution on the affected server.

Critical Impact

Remote attackers can exploit this unrestricted file upload vulnerability to upload malicious files, potentially gaining unauthorized access to the server, executing arbitrary code, or compromising sensitive job applicant data stored within the system.

Technical Details for CVE-2025-10447

Vulnerability Analysis

This vulnerability is classified under CWE-284 (Improper Access Control), specifically manifesting as an unrestricted file upload weakness. The application fails to properly validate or restrict the types of files that can be uploaded through the picture parameter in the application form functionality. Without proper file type validation, extension filtering, or content verification, the application accepts any file type submitted by users.

The network-accessible nature of this vulnerability means attackers can exploit it remotely without requiring any prior authentication or user interaction. The exploit details have been made publicly available, increasing the risk of widespread exploitation attempts against unpatched systems.

Root Cause

The root cause of this vulnerability lies in the improper access control and missing input validation in the file upload handling mechanism within /eris/applicationform.php. The application does not implement:

• File extension whitelisting or blacklisting
• MIME type verification
• Content-based file type validation
• Proper file size restrictions
• Secure file storage outside the web root

This oversight allows attackers to bypass intended security restrictions and upload executable files such as PHP web shells, which can then be accessed directly to execute arbitrary commands on the server.

Attack Vector

The attack is conducted remotely over the network. An attacker can craft a malicious HTTP request to the /eris/applicationform.php endpoint, submitting a malicious file (such as a PHP web shell) through the picture parameter. Since the application does not properly validate file uploads, the malicious file is stored on the server and can potentially be executed by directly accessing the uploaded file's URL.

The attack does not require any authentication or special privileges, making it particularly dangerous for internet-facing deployments of this application. Once a web shell is uploaded, the attacker gains the ability to execute arbitrary commands with the privileges of the web server process.

Detection Methods for CVE-2025-10447

Indicators of Compromise

• Unexpected files with executable extensions (e.g., .php, .phtml, .phar) in upload directories
• Web server access logs showing requests to /eris/applicationform.php with unusual POST data or file uploads
• New or modified files in the application's upload directory with recent timestamps
• Outbound network connections from the web server to suspicious external IP addresses

Detection Strategies

• Monitor file system changes in upload directories for new files with executable extensions
• Implement web application firewall (WAF) rules to detect and block malicious file upload attempts
• Review web server logs for suspicious POST requests to /eris/applicationform.php containing encoded or obfuscated payloads
• Deploy file integrity monitoring on the application's web directories

Monitoring Recommendations

• Enable detailed logging for the /eris/applicationform.php endpoint and review regularly
• Set up alerts for any new executable files created in upload directories
• Monitor server resource usage for anomalies that might indicate post-exploitation activity
• Implement network traffic analysis to detect potential command-and-control communications

How to Mitigate CVE-2025-10447

Immediate Actions Required

• Restrict access to the /eris/applicationform.php endpoint until a patch is available
• Implement server-side file type validation to whitelist only allowed image formats (e.g., .jpg, .png, .gif)
• Configure the web server to prevent execution of scripts in upload directories
• Review existing uploaded files for potential malicious content and remove any suspicious files

Patch Information

No official vendor patch has been released at this time. System administrators should monitor the CampCodes website for security updates. Additional technical details and community discussion can be found in the GitHub Issue Discussion and VulDB entry #323881.

Workarounds

• Disable the application form functionality entirely if not critically needed
• Implement a web application firewall with rules to block file uploads containing executable code
• Store uploaded files outside the web root directory and serve them through a secure download handler
• Apply strict file permission settings to prevent web server from executing files in upload directories

# Example: Disable PHP execution in upload directories (Apache)
# Add to .htaccess in upload directory
# php_flag engine off

# Example: Nginx configuration to block script execution
# location /uploads/ {
#     location ~ \.(php|phtml|php3|php4|php5|phps)$ {
#         deny all;
#     }
# }
