The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

When configuring Arc (e.g. during the first setup), a local web interface is provided to ease the configuration process. Such web interface lacks authentication and may thus be abused by a local attacker or malware running on the machine itself. A malicious local user or process, during a window of opportunity when the local web interface is active, may be able to extract sensitive information or change Arc's configuration. This could also lead to arbitrary code execution if a malicious update package is installed.
