CVE-2026-42569 is a critical access control vulnerability in phpVMS, a PHP application used to run and simulate an airline. Versions prior to 7.0.6 exposed a legacy import feature to unauthenticated users, resulting in an authorization bypass / missing authentication condition on that functionality. The available source material does not identify the exact vulnerable function or route, but it states that attackers could reach the legacy import capability without authentication. The issue was fixed in phpVMS 7.0.6.

This repository is a small standalone Python exploit PoC for CVE-2026-42569 targeting phpVMS. It contains one executable script, CVE-2026-42569.py, and a README describing the issue, affected versions, impact, and mitigation. The script is not part of a larger exploit framework. The exploit’s purpose is to test and potentially trigger unauthenticated access to legacy phpVMS import functionality. It iterates over four candidate web paths (/importer, /importer/index, /import, /legacy/importer), builds each URL from a user-supplied base target, and sends an HTTP POST request with form-encoded data action=import, type=full, and confirm=true. The code explicitly labels this as dangerous and states it may trigger mass deletion or a full database wipe. Success is inferred from HTTP status codes 200/301/302 combined with response content containing strings like success or imported, or simply a response body longer than 100 bytes. Operationally, this is more than a passive detector because it sends the destructive action directly rather than performing a harmless verification. The script disables TLS certificate verification (verify=False), follows redirects, uses a 10-second timeout, and prints colored console output. There is no shell payload, persistence, lateral movement, or post-exploitation logic; the capability is focused on destructive unauthenticated web requests against exposed importer routes. Repository structure is minimal: the Python file is the clear entry point and the README provides usage and mitigation guidance. Overall, this is an operational PoC for a web attack vector against phpVMS instances reportedly vulnerable in versions <= 7.0.5.
