CVE-2025-14908: Jeecg Boot Auth Bypass Vulnerability

CVE-2025-14908 Overview

CVE-2025-14908 is an improper authentication vulnerability [CWE-287] affecting JeecgBoot versions up to 3.9.0. The flaw resides in the SysTenantController.java file within the Multi-Tenant Management Module. Attackers can manipulate the ID argument to bypass authentication controls remotely without user interaction. The vendor has released a patch under commit e1c8f00bf2a2e0edddbaa8119afe1dc92d9dc1d2. Public disclosure of exploit details has occurred, increasing the risk of opportunistic exploitation against unpatched instances.

Critical Impact
Remote attackers with low privileges can bypass tenant isolation controls and access resources belonging to other tenants in JeecgBoot deployments.

Affected Products

JeecgBoot versions up to and including 3.9.0
jeecg-boot/jeecg-module-system/jeecg-system-biz module
Multi-Tenant Management Module component

Technical Details for CVE-2025-14908

Vulnerability Analysis

The vulnerability exists in the Multi-Tenant Management Module of JeecgBoot, a low-code development platform. The SysTenantController.java controller handles tenant management operations but fails to properly authenticate requests that manipulate the ID parameter. This weakness maps to [CWE-287] Improper Authentication.

An authenticated attacker with low privileges can send crafted requests over the network to interact with tenant records they should not access. Because JeecgBoot supports multi-tenant deployments, this flaw undermines the isolation boundary between tenants. Successful exploitation may expose configuration data or allow limited manipulation across tenant boundaries.

The exploit has been publicly disclosed, according to the vendor advisory. This lowers the barrier for opportunistic attackers targeting internet-facing JeecgBoot instances.

Root Cause

The root cause is missing or insufficient authentication checks in the controller method that processes the ID argument in SysTenantController.java. The controller trusts the client-supplied identifier without verifying that the requesting user is authorized to act on the referenced tenant record.

Attack Vector

The attack is initiated remotely over the network. The attacker requires low-level privileges on the JeecgBoot instance to reach the vulnerable endpoint. No user interaction is required to trigger the flaw. The attacker submits a manipulated ID value to the tenant management endpoint to bypass the intended authentication logic.

Refer to the GitHub Issue Tracker and the VulDB entry #337432 for additional technical context.

Detection Methods for CVE-2025-14908

Indicators of Compromise

Unexpected HTTP requests to tenant management endpoints under /sys/tenant/ or related paths within SysTenantController
Requests containing unusual or sequentially enumerated ID parameter values from a single source
Access to tenant records by user accounts outside their assigned tenant context
Application logs showing successful tenant operations without corresponding administrative authorization events

Detection Strategies

Review JeecgBoot application logs for requests to SysTenantController endpoints from non-administrative accounts
Correlate authentication events with tenant management API calls to identify authorization gaps
Deploy web application firewall rules that inspect ID parameter values on tenant management routes
Monitor for cross-tenant data access patterns indicative of authentication bypass attempts

Monitoring Recommendations

Enable verbose logging on the jeecg-system-biz module for all tenant controller operations
Alert on any tenant list, read, update, or delete operations performed by non-privileged accounts
Track HTTP 200 responses to tenant management endpoints paired with low-privilege session tokens
Baseline normal tenant management activity and flag deviations for investigation

How to Mitigate CVE-2025-14908

Immediate Actions Required

Apply the vendor patch identified by commit e1c8f00bf2a2e0edddbaa8119afe1dc92d9dc1d2 from the JeecgBoot GitHub repository
Restrict network access to the JeecgBoot administrative interface until patching is complete
Audit existing tenant records for unauthorized modifications or unexpected additions
Rotate credentials for accounts that may have interacted with the vulnerable endpoint

Patch Information

The vendor has released a patch referenced as commit e1c8f00bf2a2e0edddbaa8119afe1dc92d9dc1d2 and additional fix 67795493bdc579e489d3ab12e52a1793c4f8a0ee. Administrators should upgrade to a JeecgBoot version that incorporates these commits. Full patch details are available in the official commit.

Workarounds

Restrict access to /sys/tenant/ endpoints at the reverse proxy or WAF layer to trusted administrative IP ranges
Enforce strict role-based access control on the Multi-Tenant Management Module through custom authentication filters
Disable the Multi-Tenant Management Module if it is not required by the deployment
Isolate JeecgBoot administrative interfaces on a segmented internal network

bash

# Configuration example - nginx location block to restrict tenant management access
location ~ ^/jeecg-boot/sys/tenant/ {
    allow 10.0.0.0/24;   # Trusted admin subnet
    deny all;
    proxy_pass http://jeecgboot_backend;
}
