A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system files.

Solution

No solution given by the vendor.


Workaround

As a prevention measure, avoid extracting archives from untrusted sources using BusyBox utilities. If extraction of untrusted archives is necessary, perform it within a highly isolated and restricted environment, such as a container with a read-only root filesystem and minimal privileges, to limit the potential impact of arbitrary file overwrites.
