Linux rsync allows files to be written outside a module`s path
| rsync-write-files (16014) |  Medium Risk |
Description:
rsync could allow a remote attacker to write files outside of the directory. When running non-read-only rsync without enabling chroot, a remote attacker can send a path to the rsync daemon to write files to directories outside a module's path.
