CriticalCVSS 9.8Exploitation Probability (EPSS)
Low risk36th percentile - higher than 36% of all known CVEs
Summary
Snap One WattBox 800 and 820 series firmware versions prior to 2.10.0.0 contain undisclosed diagnostic HTTP endpoints that require only the device MAC address and service tag for authentication, both of which are printed in plaintext on the physical device label. Attackers with access to the device label or documentation containing these values can authenticate to the several endpoints and execute arbitrary commands as root on the device.
Risk Assessment
An attacker with physical access to the device can gain full control, potentially leading to network compromise and data theft.
Recommendation
Upgrade Snap One WattBox firmware to version 2.10.0.0 or later, and secure physical access to device labels.
