Component: Not specified by the source

Attack conditions (Vendor/CNA, CVSS 3.1): Network (remote) · No privileges required · No user interaction required

What an attacker can do

An unauthenticated, remote attacker could execute arbitrary code with root privileges or cause a Denial-of-Service (DoS) on an affected device. Vendor/CNA’s CVSS 3.1 assessment (base score 9.8/10) rates confidentiality, integrity and availability impact as high.
