CVE-2025-6329: Real Estate Management Auth Bypass Flaw

CVE-2025-6329 Overview

CVE-2025-6329 is an authorization bypass vulnerability in ScriptAndTools Real Estate Management System 1.0. The flaw resides in the userdelete.php file, which functions as the User Delete Handler component. Attackers can manipulate the ID parameter to delete user accounts without proper authorization checks. The vulnerability is remotely exploitable over the network and requires only low-level privileges. Public disclosure of the exploit increases the risk of opportunistic abuse against exposed installations. The weakness is classified under [CWE-285] Improper Authorization.

Critical Impact
Remote attackers with low privileges can bypass authorization controls in userdelete.php to delete arbitrary user records, affecting integrity and availability of the application.

Affected Products

ScriptAndTools Real Estate Management System 1.0
Component: User Delete Handler (userdelete.php)
Parameter: ID

Technical Details for CVE-2025-6329

Vulnerability Analysis

The vulnerability stems from missing authorization checks in the userdelete.php endpoint of ScriptAndTools Real Estate Management System 1.0. The handler accepts an ID argument that identifies the user record targeted for deletion. The application does not verify whether the authenticated session has the required role or ownership of the target record before executing the deletion. An attacker with any valid low-privilege account can supply arbitrary ID values to remove other users.

The issue maps to [CWE-285] Improper Authorization. The action is performed remotely over HTTP without user interaction. Public disclosure of exploit details lowers the barrier for opportunistic abuse. EPSS data places the probability of exploitation activity below one percent at the time of analysis.

Root Cause

The root cause is the absence of server-side authorization logic between request parsing and the database delete operation in userdelete.php. The script trusts the ID parameter supplied by the client and acts on it without confirming the caller's permission scope. This pattern is a textbook Insecure Direct Object Reference paired with missing access control.

Attack Vector

The attack vector is network-based. An authenticated attacker sends a crafted HTTP request to userdelete.php with the ID parameter set to a target user identifier. The server processes the deletion without validating session privileges. No social engineering or local access is required. The exploitation flow and parameter manipulation are documented in the Web Security Insights blog post and the corresponding VulDB entry.

Detection Methods for CVE-2025-6329

Indicators of Compromise

Unexpected HTTP requests to userdelete.php containing ID parameter values that do not match the requesting user's account
Missing user records or sudden drops in the application's users table not tied to administrative activity
Web server access logs showing repeated GET or POST requests to userdelete.php from a single low-privilege session

Detection Strategies

Inspect application access logs for invocations of userdelete.php and correlate the ID parameter with the session owner
Enable database audit logging on the users table to capture DELETE statements with timestamps and originating session identifiers
Deploy a web application firewall rule that blocks requests to userdelete.php unless they originate from an authenticated administrative role

Monitoring Recommendations

Alert on any deletion activity in the user table outside of approved administrative workflows
Track sequential ID enumeration patterns against userdelete.php indicative of automated abuse
Forward web and database logs into a centralized analytics platform to correlate session, IP, and deletion events

How to Mitigate CVE-2025-6329

Immediate Actions Required

Restrict network access to the ScriptAndTools Real Estate Management System administrative paths using IP allowlisting until a patched build is available
Disable or remove the userdelete.php endpoint if it is not required for current business operations
Audit existing user records for unauthorized deletions and restore from backup if discrepancies are found

Patch Information

No vendor advisory or patched release is referenced in the available data for CVE-2025-6329. Operators should monitor the ScriptAndTools vendor channels and the VulDB entry for an official fix. Until a patch is released, mitigations should focus on access restriction and code-level authorization checks.

Workarounds

Add a server-side role check in userdelete.php that validates the session's privileges before processing the ID parameter
Implement an ownership check that confirms the caller is either an administrator or the owner of the target user record
Place the application behind a reverse proxy that requires multi-factor authentication for any path matching userdelete.php

bash

# Example Apache configuration to restrict access to userdelete.php
<Files "userdelete.php">
    Require ip 10.0.0.0/8
    Require valid-user
</Files>
