CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2024-1638 – Bluetooth characteristic LESC security requirement not enforced without additional flags
https://notcve.org/view.php?id=CVE-2024-1638
The documentation specifies that the BT_GATT_PERM_READ_LESC and BT_GATT_PERM_WRITE_LESC defines for a Bluetooth characteristic: Attribute read/write permission with LE Secure Connection encryption. If set, requires that LE Secure Connections is used for read/write access, however this is only true when it is combined with other permissions, namely BT_GATT_PERM_READ_ENCRYPT/BT_GATT_PERM_READ_AUTHEN (for read) or BT_GATT_PERM_WRITE_ENCRYPT/BT_GATT_PERM_WRITE_AUTHEN (for write), if these additional permissions are not set (even in secure connections only mode) then the stack does not perform any permission checks on these characteristics and they can be freely written/read. La documentación especifica que BT_GATT_PERM_READ_LESC y BT_GATT_PERM_WRITE_LESC definen para una característica de Bluetooth: Atributo permiso de lectura/escritura con cifrado LE Secure Connection. Si está configurado, requiere que se utilice LE Secure Connections para acceso de lectura/escritura; sin embargo, esto solo es cierto cuando se combina con otros permisos, a saber, BT_GATT_PERM_READ_ENCRYPT/BT_GATT_PERM_READ_AUTHEN (para lectura) o BT_GATT_PERM_WRITE_ENCRYPT/BT_GATT_PERM_WRITE_AUTHEN (para escritura), si estos permisos adicionales no están configurados (incluso en el modo de solo conexiones seguras), entonces la pila no realiza ninguna verificación de permisos sobre estas características y se pueden escribir/leer libremente. • https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-p6f3-f63q-5mc2 • CWE-20: Improper Input Validation •
