CVE-2025-45611: Hope-boot Auth Bypass Vulnerability

CVE-2025-45611 Overview

CVE-2025-45611 is an authentication bypass vulnerability affecting the /user/edit/ component of hope-boot v1.0.0, an open-source Java-based web application framework developed by java-aodeng. The vulnerability stems from incorrect access control implementation that allows attackers to bypass authentication mechanisms via specially crafted GET requests. This flaw enables unauthorized access to user editing functionality, potentially compromising user account integrity and system security.

Critical Impact

Attackers can bypass authentication entirely via network-based attacks without requiring any privileges or user interaction, potentially gaining unauthorized access to user management functions and sensitive data.

Affected Products

Technical Details for CVE-2025-45611

Vulnerability Analysis

This vulnerability is classified as Improper Access Control (CWE-284), representing a fundamental failure in the application's authorization framework. The /user/edit/ endpoint in hope-boot v1.0.0 lacks proper authentication validation, allowing unauthenticated attackers to access and potentially modify user data through the network.

The attack can be executed remotely without requiring authentication credentials, user interaction, or elevated privileges. Successful exploitation could result in complete compromise of data confidentiality, integrity, and system availability. An attacker exploiting this flaw could view sensitive user information, modify user accounts, or potentially escalate to broader system compromise.

Root Cause

The root cause of this vulnerability lies in insufficient access control validation within the /user/edit/ component. The application fails to properly verify user authentication status or authorization permissions before processing incoming requests to this endpoint. This allows the security checks that should protect user management functionality to be completely bypassed.

Attack Vector

The attack vector is network-based and requires no special prerequisites. An attacker can craft a malicious GET request targeting the /user/edit/ endpoint to bypass authentication controls. The attack does not require valid credentials, elevated privileges, or any form of user interaction, making it highly exploitable in internet-facing deployments.

The vulnerability exists in the request handling logic where authentication verification is either missing or improperly implemented. By sending a specifically crafted HTTP GET request to the vulnerable endpoint, an attacker can gain unauthorized access to user editing functionality that should be restricted to authenticated administrators.

Detection Methods for CVE-2025-45611

Indicators of Compromise

• Unusual HTTP GET requests to /user/edit/ endpoints from unauthenticated sessions or unexpected IP addresses
• Access logs showing successful responses to /user/edit/ requests without corresponding authentication events
• Unexpected user account modifications or user data access patterns
• Web application firewall alerts for suspicious requests targeting user management endpoints

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and alert on requests to /user/edit/ endpoints lacking proper session tokens
• Configure application logging to capture all requests to sensitive user management endpoints with authentication context
• Deploy behavioral analytics to identify anomalous access patterns to administrative functions
• Enable audit logging for all user modification operations to establish baseline and detect deviations

Monitoring Recommendations

• Review web server access logs for requests to /user/edit/ from unauthenticated sources
• Monitor for unusual patterns of user account modifications outside normal administrative activity
• Set up alerts for any access to user management endpoints from unexpected network ranges
• Implement real-time monitoring of authentication bypass attempts using SIEM solutions

How to Mitigate CVE-2025-45611

Immediate Actions Required

• Restrict network access to hope-boot instances to trusted IP ranges until patching is complete
• Implement additional authentication controls at the web server or reverse proxy level for /user/edit/ endpoints
• Enable comprehensive logging on all user management endpoints to detect exploitation attempts
• Review audit logs for any evidence of prior unauthorized access to user editing functionality

Patch Information

Organizations running hope-boot v1.0.0 should monitor the project's GitHub repository for security updates. Details regarding the vulnerability and potential fixes are tracked in GitHub Issue #86. Until an official patch is released, implement the workarounds described below.

Workarounds

• Deploy a web application firewall (WAF) to enforce authentication requirements on /user/edit/ endpoints
• Implement network segmentation to restrict access to hope-boot administrative functions from untrusted networks
• Add authentication middleware at the reverse proxy or load balancer level to protect vulnerable endpoints
• Consider disabling the /user/edit/ endpoint entirely if not critical to operations until a patch is available

# Example: Nginx configuration to restrict access to vulnerable endpoint
location /user/edit/ {
    # Deny all access until authentication is properly implemented
    deny all;
    # Or restrict to trusted IP ranges only
    # allow 10.0.0.0/8;
    # deny all;
}
