CVE-2025-70150: Membership Management Auth Bypass Flaw

CVE-2025-70150 Overview

CVE-2025-70150 is a critical missing authentication vulnerability affecting CodeAstro Membership Management System version 1.0. The vulnerability exists in the delete_members.php endpoint, which fails to implement proper authentication checks before processing member deletion requests. This allows unauthenticated remote attackers to delete arbitrary member records by directly accessing the vulnerable endpoint and manipulating the id parameter.

Critical Impact

Unauthenticated attackers can remotely delete arbitrary member records from the database, leading to complete data loss and integrity compromise without requiring any authentication or user interaction.

Affected Products

• CodeAstro Membership Management System 1.0
• PHP-based membership management installations using delete_members.php

Technical Details for CVE-2025-70150

Vulnerability Analysis

This vulnerability is classified under CWE-862 (Missing Authorization), which occurs when a web application fails to perform access control checks on protected resources. In the case of CodeAstro Membership Management System 1.0, the delete_members.php script directly processes deletion requests without verifying whether the requester is authenticated or authorized to perform such operations.

The impact of this vulnerability is severe as it affects all three CIA triad components. An attacker can compromise confidentiality by probing member IDs to discover valid records, destroy data integrity by deleting legitimate member records, and impact availability by mass-deleting membership data from the system.

Root Cause

The root cause of CVE-2025-70150 is the complete absence of authentication and authorization checks in the delete_members.php file. The endpoint directly accepts the id parameter from user input and executes the corresponding database deletion operation without first validating the user's session, role, or permissions. This represents a fundamental failure in implementing proper access control mechanisms, a common issue in legacy PHP applications that lack proper security architecture.

Attack Vector

The attack vector is network-based, requiring no authentication, no user interaction, and low attack complexity. An attacker can exploit this vulnerability by simply sending a direct HTTP request to the delete_members.php endpoint with a manipulated id parameter. The attacker does not need to be logged in or possess any valid credentials.

The exploitation process involves:

1. Identifying the target system running CodeAstro Membership Management System 1.0
2. Crafting a direct request to the delete_members.php endpoint
3. Supplying an arbitrary member id parameter value
4. The system processes the deletion without authentication verification

Attackers can enumerate valid member IDs through sequential requests and systematically delete all member records from the database. For detailed technical analysis, refer to the security researcher's writeup on GitHub.

Detection Methods for CVE-2025-70150

Indicators of Compromise

• Unexpected or unauthorized HTTP requests targeting delete_members.php from external IP addresses
• Multiple sequential requests to delete_members.php with incrementing or varying id parameter values
• Database audit logs showing member record deletions without corresponding authenticated sessions
• Sudden decrease in member record counts without legitimate administrative activity

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block unauthenticated requests to delete_members.php
• Monitor access logs for requests to delete_members.php originating from IP addresses not associated with administrative users
• Deploy database activity monitoring to alert on bulk DELETE operations against member tables
• Configure intrusion detection systems (IDS) to flag repeated parameter manipulation patterns

Monitoring Recommendations

• Enable comprehensive logging for all administrative endpoints including delete_members.php
• Implement real-time alerting for any database modifications to member records
• Monitor for anomalous patterns such as requests outside business hours or from unexpected geographic locations
• Regularly audit member record counts and investigate unexplained decreases

How to Mitigate CVE-2025-70150

Immediate Actions Required

• Immediately restrict access to delete_members.php at the web server level until a proper fix is implemented
• Implement IP-based access controls to limit administrative endpoint access to trusted networks only
• Back up the member database to prevent permanent data loss from potential exploitation
• Review access logs for evidence of prior exploitation attempts

Patch Information

As of the last update on 2026-02-19, no official vendor patch has been released for this vulnerability. Organizations using CodeAstro Membership Management System 1.0 should implement defensive measures until an official fix becomes available. Monitor the PHP Scripts Online product page for vendor updates and security advisories.

Workarounds

• Add session validation checks at the beginning of delete_members.php to verify user authentication before processing any requests
• Implement role-based access control (RBAC) to ensure only authorized administrators can perform deletion operations
• Use .htaccess rules or web server configuration to restrict access to administrative endpoints
• Consider deploying a reverse proxy with authentication requirements for all administrative functions

# Apache .htaccess workaround to restrict access to delete_members.php
<Files "delete_members.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    # Replace with your trusted admin network range
</Files>
