CVE-2025-70146: Time Table Generator Auth Bypass Flaw

CVE-2025-70146 Overview

CVE-2025-70146 is a critical authentication bypass vulnerability affecting ProjectWorlds Online Time Table Generator version 1.0. The vulnerability exists due to missing authentication controls in multiple administrative action scripts located under the /admin/ directory. Remote attackers can exploit this flaw to perform unauthorized administrative operations, including adding and deleting records, by sending direct HTTP requests to affected endpoints without requiring a valid session.

Critical Impact

Unauthenticated attackers can perform arbitrary administrative operations on the application, potentially leading to complete data manipulation, deletion of critical records, and disruption of time table management functionality.

Affected Products

• ProjectWorlds Online Time Table Generator 1.0
• Administrative scripts under /admin/ directory
• PHP-based web application with MySQL backend

Technical Details for CVE-2025-70146

Vulnerability Analysis

This vulnerability is classified as CWE-306 (Missing Authentication for Critical Function), which represents a fundamental security design flaw where critical administrative functionality is exposed without requiring proper authentication. The affected application fails to implement session validation or any form of authentication checks before processing requests to administrative endpoints.

The vulnerability enables attackers to directly interact with administrative functionality that should be restricted to authenticated administrators only. Since the application does not validate whether incoming requests originate from authenticated sessions, any remote user can craft HTTP requests to perform privileged operations such as creating new records or deleting existing data from the time table system.

Root Cause

The root cause of this vulnerability lies in the absence of authentication middleware or session verification logic in the administrative PHP scripts. The scripts under the /admin/ directory process incoming requests and execute database operations without first confirming that the requester has valid administrative credentials or an authenticated session. This architectural flaw allows the application to accept and process requests from any source, regardless of authorization status.

Attack Vector

The attack vector is network-based and requires no user interaction. An attacker can exploit this vulnerability by identifying the vulnerable administrative endpoints and sending crafted HTTP requests directly to them. The exploitation process typically involves:

1. Discovering the administrative endpoints under the /admin/ directory
2. Analyzing the expected parameters for each administrative action
3. Sending direct HTTP POST or GET requests to endpoints such as those handling record additions or deletions
4. Executing unauthorized administrative operations without providing any authentication credentials

The vulnerability is particularly severe because it requires no privileges, no authentication, and can be exploited remotely over the network. For detailed technical analysis and exploitation methodology, refer to the GitHub CVE-2025-70146 Analysis.

Detection Methods for CVE-2025-70146

Indicators of Compromise

• Unexpected HTTP requests to /admin/ endpoints from unauthenticated sources or external IP addresses
• Database modification logs showing records being added or deleted without corresponding authenticated admin sessions
• Web server access logs containing direct requests to administrative action scripts without prior authentication page access
• Anomalous patterns of DELETE or INSERT operations in the application database

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and alert on direct access attempts to /admin/ endpoints without valid session cookies
• Deploy log analysis to correlate administrative actions with authenticated session records
• Configure intrusion detection systems to flag HTTP requests to sensitive administrative paths originating from external networks
• Monitor database audit logs for unauthorized modifications to time table records

Monitoring Recommendations

• Enable comprehensive access logging for all scripts under the /admin/ directory
• Implement real-time alerting for any administrative operations performed without valid session tokens
• Review web server logs periodically for patterns indicating reconnaissance or exploitation attempts against administrative endpoints
• Utilize application performance monitoring tools to track unusual spikes in administrative endpoint requests

How to Mitigate CVE-2025-70146

Immediate Actions Required

• Restrict access to the /admin/ directory using web server access controls (IP whitelisting, HTTP authentication)
• Take the application offline or disable public access if it cannot be immediately patched
• Review database logs for any unauthorized modifications that may have occurred
• Implement network-level access restrictions to limit administrative endpoint access to trusted networks only

Patch Information

No official vendor patch has been identified in the available CVE data. Users are advised to monitor the Project Worlds Tool Guide for updates. In the absence of an official patch, implementing the workarounds below is strongly recommended to protect against exploitation.

Workarounds

• Add session validation checks at the beginning of each administrative script to verify user authentication before processing requests
• Configure .htaccess rules to require HTTP authentication for all files under the /admin/ directory
• Implement IP-based access control lists to restrict administrative endpoint access to known administrator IP addresses
• Deploy a reverse proxy with authentication enforcement in front of the application

# Apache .htaccess configuration to restrict /admin/ access
# Place this file in the /admin/ directory

AuthType Basic
AuthName "Restricted Administrative Area"
AuthUserFile /path/to/.htpasswd
Require valid-user

# Optional: IP-based restriction
# Order Deny,Allow
# Deny from all
# Allow from 192.168.1.0/24
