There exists an Improper Neutralization of Special Elements used in an
OS Command with root privileges during a restore operation due to the
missing validation of the names of files included in the input
package. By restoring a specifically crafted package, a remote low-
privileged attacker can execute arbitrary system commands with root
privileges on the device, leading to a full compromise.

This plugin only works with Tenable.ot.
