> Path traversal in the Knox Admin API resource-management endpoints (PUT
> /admin/api/v1/\{providerconfig,descriptors,topologies}/\{name}). The
> client-supplied resource name is URL-decoded and validated against
> RESOURCE_NAME_PATTERN = ^[\w-/.]+$, whose character class admits / and . (the
> - is literal), so a ../ traversal passes validation. The decoded name is then
> written via new File(dest, name) + FileUtils.writeStringToFile with no
> canonical-path containment check, so an authenticated admin-role user can
> write/overwrite a file outside the managed
> shared-providers/descriptors/topologies directories, with an attacker-chosen
> filename and extension (getFileNameForResource keeps the name verbatim when
> it already has a .)
