Title
Lack of TLS certificate validation when connecting Arc to a Guardian or CMC, in Arc before v2.2.0
Summary
The server certificate was not verified when an Arc agent connected to a Guardian or CMC.
A malicious actor could perform a man-in-the-middle attack and intercept the communication between the Arc agent and the Guardian or CMC. This could result in theft of the client token and sensitive information (such as assets and alerts), impersonation of the server, or injection of spoofed data (such as false asset information or vulnerabilities) into the Guardian or CMC.

Title
Missing authentication for local web interface in Arc before v1.6.0
Summary
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.

Title
Lack of TLS certificate validation when connecting Arc to a Guardian or CMC, in Arc before v2.2.0
Summary
The server certificate was not verified when an Arc agent connected to a Guardian or CMC.
A malicious actor could perform a man-in-the-middle attack and intercept the communication between the Arc agent and the Guardian or CMC. This could result in theft of the client token and sensitive information (such as assets and alerts), impersonation of the server, or injection of spoofed data (such as false asset information or vulnerabilities) into the Guardian or CMC.

Title
Missing authentication for local web interface in Arc before v1.6.0
Summary
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.
