Affected Target

Field	Value
Software / System	phpVMS (Virtual Airline Management System)
Versions Affected	≤ 7.0.5 (fixed in 7.0.6)
Language / Platform	PHP web app (target); Python (PoC)
Authentication Required	No
Network Access Required	Yes — HTTP access to the phpVMS instance

Summary

phpVMS ships legacy data-import endpoints (/importer, /importer/index, /import, /legacy/importer) that were intended to be restricted but remain reachable without authentication in versions ≤ 7.0.5. These endpoints accept import/action parameters capable of triggering mass deletion or full database wipe operations, allowing an unauthenticated attacker to destroy flights, users, schedules, and other critical virtual-airline data.

Vulnerability Details

Root Cause

The legacy importer routes are missing the access-control checks applied to the rest of the application (broken/missing authorization — CWE-862/CWE-284 class issue). Because these routes predate the current auth middleware and were never fully deprecated/removed, they remain directly reachable by unauthenticated HTTP requests and still perform their original destructive import/reset behavior (mass delete / TRUNCATE-style operations) when invoked with the right parameters.

Attack Vector

Send an unauthenticated POST request to one of the legacy endpoints (/importer, /importer/index, /import, /legacy/importer).
Supply import parameters indicating a full/destructive import, e.g. action=import&type=full&confirm=true.
If the endpoint is reachable and unprotected, the server processes the request as a legitimate import job, which can mass-delete or wipe the underlying database tables.

Impact

Complete unauthenticated compromise of application data integrity: mass deletion of flights, users, and schedules, up to a full database wipe, resulting in total loss of service and data for the virtual airline platform.

Environment / Lab Setup

Target: phpVMS <= 7.0.5 with legacy importer routes exposed
Client:  Python 3 with `requests` and `colorama`

Proof of Concept

PoC Script

See CVE-2026-42569.py in this folder.

1
2
pip install requests colorama
python3 CVE-2026-42569.py http://target.com

The script probes each legacy importer endpoint with a destructive import payload (action=import&type=full&confirm=true) and reports whether the target responded in a way indicating the endpoint is reachable and the destructive operation would proceed, confirming exposure to CVE-2026-42569.

Detection & Indicators of Compromise

- Web server access logs showing unauthenticated POST requests to
  /importer, /importer/index, /import, or /legacy/importer.
- Sudden, unexplained mass DELETE/TRUNCATE activity in the phpVMS
  database logs.
- Requests carrying import parameters such as action=import,
  type=full, confirm=true from IPs without an authenticated session.

Signs of compromise:

Sudden loss of flight, user, or schedule records without a corresponding legitimate admin action.
Application logs showing import jobs triggered by unauthenticated sessions.

Remediation

Action	Detail
Primary fix	Upgrade to phpVMS 7.0.6 or newer, which restricts access to the legacy import routes
Interim mitigation	Block or remove access to `/importer` and `/import` routes at the web server level (see below) and maintain regular database backups
