Descriptions

In GNOME Shell through 45.7, a portal helper can be launched automatically (without user confirmation) based on network responses provided by an adversary (e.g., an adversary who controls the local Wi-Fi network), and subsequently loads untrusted JavaScript code, which may lead to resource consumption or other impacts depending on the JavaScript code's behavior.

En GNOME Shell hasta la versión 45.7, se puede iniciar automáticamente un asistente de portal (sin confirmación del usuario) en función de las respuestas de red proporcionadas por un adversario (por ejemplo, un adversario que controla la red Wi-Fi local) y, posteriormente, carga código JavaScript que no es de confianza, lo que puede conducir al consumo de recursos u otros impactos dependiendo del comportamiento del código JavaScript.

A vulnerability was found in GNOME Shell. A portal helper can be launched automatically without user confirmation based on the network responses provided by an adversary.

It was discovered that GNOME Shell incorrectly opened the portal helper automatically when detecting a captive network portal. A remote attacker could possibly use this issue to load arbitrary web pages containing JavaScript, leading to resource consumption or other attacks.
