Stored script execution via persistent XSS

Published Jan 7, 2020 · Updated Aug 6, 2024

Cross-site scripting in PQI AirCard firmware through 147.0 allows remote authenticated users to affect other users via stored web content. The public record identifies persistent XSS but does not disclose the specific AirCard field or handler that stores and renders the input without proper neutralization. Exploitation requires a network connection, valid authentication, and victim interaction with the affected web content; the documented impact is unauthorized script execution in a user's web session.
