Severity ?
7.3 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A vulnerability was found in MicroPython 1.23.0. It has been classified as critical. Affected is the function mp_vfs_umount of the file extmod/vfs.c of the component VFS Unmount Handler. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The name of the patch is 29943546343c92334e8518695a11fc0e2ceea68b. It is recommended to apply a patch to fix this issue. In the VFS unmount process, the comparison between the mounted path string and the unmount requested string is based solely on the length of the unmount string, which can lead to a heap buffer overflow read.

Se ve afectada la funci\u00f3n mp_vfs_umount del archivo extmod/vfs.c del componente VFS Unmount Handler. La manipulaci\u00f3n provoca un desbordamiento del b\u00fafer basado en el mont\u00f3n. Es posible lanzar el ataque de forma remota. El exploit se ha hecho p\u00fablico y se puede utilizar. El nombre del parche es 29943546343c92334e8518695a11fc0e2ceea68b. Se recomienda aplicar un parche para solucionar este problema. En el proceso de desmontaje de VFS, la comparaci\u00f3n entre la cadena de ruta montada y la cadena solicitada de desmontaje se basa \u00fanicamente en la longitud de la cadena de desmontaje, lo que puede provocar una lectura de desbordamiento del b\u00fafer del mont\u00f3n."
