CVE-2024-32462

Estado: AnalizadaAlta (8.4)—💥 PoC

Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. in versions before 1.10.9, 1.12.9, 1.14.6, and 1.15.8, a malicious or compromised Flatpak app could execute arbitrary code outside its sandbox. Normally, the `--command` argument of `flatpak run` expects to be given a command to run in the specified Flatpak app, optionally along with some arguments. However it is possible to instead pass `bwrap` arguments to `--command=`, such as `--bind`.

Leer descripción completaMostrar menos

It's possible to pass an arbitrary `commandline` to the portal interface `org.freedesktop.portal.Background.RequestBackground` from within a Flatpak app. When this is converted into a `--command` and arguments, it achieves the same effect of passing arguments directly to `bwrap`, and thus can be used for a sandbox escape. The solution is to pass the `--` argument to `bwrap`, which makes it stop processing options. This has been supported since bubblewrap 0.3.0. All supported versions of Flatpak require at least that version of bubblewrap. xdg-desktop-portal version 1.18.4 will mitigate this vulnerability by only allowing Flatpak apps to create .desktop files for commands that do not start with --. The vulnerability is patched in 1.15.8, 1.10.9, 1.12.9, and 1.14.6.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.

Normalmente, el argumento `--command` de `flatpak run` espera recibir un comando para ejecutar en la aplicación Flatpak especificada, opcionalmente junto con algunos argumentos. Sin embargo, es posible pasar argumentos `bwrap` a `--command=`, como `--bind`. Es posible pasar una \"línea de comando\" arbitraria a la interfaz del portal \"org.freedesktop.portal.Background.RequestBackground\" desde una aplicación Flatpak. Cuando esto se convierte en un `--command` y argumentos, logra el mismo efecto de pasar argumentos directamente a `bwrap` y, por lo tanto, puede usarse para un escape sandbox. La solución es pasar el argumento `--` a `bwrap`, lo que hace que deje de procesar las opciones. Esto ha sido compatible desde bubblewrap 0.3.0. Todas las versiones compatibles de Flatpak requieren al menos esa versión de bubblewrap. xdg-desktop-portal versión 1.18.4 mitigará esta vulnerabilidad al permitir que las aplicaciones Flatpak solo creen archivos .desktop para comandos que no comiencen con --.
