CVE-2025-5390: Huayi-tec Jeewms Auth Bypass Vulnerability

CVE-2025-5390 Overview

A critical improper access control vulnerability has been identified in JeeWMS, an open-source warehouse management system developed by Huayi-tec. The vulnerability exists in the filedeal function within the /systemController/filedeal.do endpoint of the File Handler component. Due to improper access controls, an authenticated attacker can remotely manipulate file operations without proper authorization checks, potentially leading to unauthorized file access or manipulation.

Critical Impact

Remote attackers with low-level privileges can exploit improper access controls in the JeeWMS File Handler to perform unauthorized file operations, potentially compromising system integrity and data confidentiality.

Affected Products

• Huayi-tec JeeWMS up to version 20250504
• JeeWMS installations using the vulnerable /systemController/filedeal.do endpoint
• All deployments without proper access control patches applied

Technical Details for CVE-2025-5390

Vulnerability Analysis

The vulnerability resides in the filedeal function of JeeWMS's File Handler component. The affected endpoint /systemController/filedeal.do fails to properly validate user authorization before processing file-related requests. This improper access control implementation (CWE-266: Incorrect Privilege Assignment) allows authenticated users with minimal privileges to perform file operations that should be restricted to higher-privileged accounts.

The attack can be initiated remotely over the network, requiring only low-level user authentication. The vulnerability impacts confidentiality, integrity, and availability of the system, as unauthorized file manipulation could lead to data exposure, modification of critical files, or disruption of warehouse management operations.

Root Cause

The root cause of this vulnerability is the absence of proper authorization checks in the filedeal function. The File Handler component processes incoming requests to the /systemController/filedeal.do endpoint without verifying whether the requesting user has sufficient privileges to perform the requested file operation. This design flaw allows any authenticated user to bypass intended access restrictions and manipulate files beyond their authorized scope.

Attack Vector

The attack is executed remotely over the network. An attacker with valid low-level credentials to the JeeWMS system can craft malicious requests to the /systemController/filedeal.do endpoint. By manipulating request parameters, the attacker can perform unauthorized file operations such as reading, modifying, or deleting files that should be protected by access controls.

The vulnerability does not require user interaction and can be exploited with low attack complexity. The attacker must possess valid authentication credentials, but no elevated privileges are required to perform the attack.

Detection Methods for CVE-2025-5390

Indicators of Compromise

• Unusual HTTP requests targeting /systemController/filedeal.do from low-privileged user accounts
• Unexpected file access patterns or modifications in the JeeWMS file storage directories
• Authentication logs showing repeated access to the File Handler endpoint by users who should not have file management privileges
• Web server access logs containing anomalous parameters in requests to the filedeal function

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and alert on suspicious requests to /systemController/filedeal.do
• Configure intrusion detection systems (IDS) to identify access control bypass attempts targeting the File Handler component
• Deploy application-level logging to capture all file operations performed through the filedeal function
• Establish baseline user behavior profiles and alert on deviations in file access patterns

Monitoring Recommendations

• Enable verbose logging for all requests to the /systemController/filedeal.do endpoint
• Monitor file system activity in JeeWMS directories for unauthorized modifications
• Implement real-time alerting for file operations performed by users with insufficient privilege levels
• Review authentication and authorization logs regularly for signs of access control bypass attempts

How to Mitigate CVE-2025-5390

Immediate Actions Required

• Restrict network access to the /systemController/filedeal.do endpoint to only authorized administrative users
• Implement additional authentication and authorization checks at the network perimeter level
• Review and audit all user accounts with access to the JeeWMS system to ensure principle of least privilege
• Consider temporarily disabling the File Handler functionality until a proper fix can be applied

Patch Information

JeeWMS does not use traditional versioning, which makes tracking affected and unaffected releases difficult. Organizations using JeeWMS should monitor the official repository for security updates and apply any available patches as soon as they become available. For technical details and issue tracking, refer to the Gitee Issue Report. Additional vulnerability intelligence is available through VulDB.

Workarounds

• Implement network-level access controls to restrict access to the vulnerable endpoint from untrusted networks
• Configure a reverse proxy or web application firewall to filter and validate requests to /systemController/filedeal.do
• Apply role-based access controls at the application layer to limit which users can access file management functions
• Consider implementing file integrity monitoring to detect unauthorized file modifications

# Example: Restrict access to vulnerable endpoint using nginx
# Add to your nginx server configuration
location /systemController/filedeal.do {
    # Restrict to trusted admin IP addresses only
    allow 192.168.1.0/24;
    deny all;
    
    # Enable access logging for audit purposes
    access_log /var/log/nginx/jeewms_filedeal_access.log;
}
