Summary

The "update" binary in the firmware of the affected product sends attempts to mount to a hard-coded, routable IP address, bypassing existing device network settings to do so. The function triggers if the 'C' button is pressed at a specific time during the boot process. If an attacker is able to control or impersonate this IP address, they could upload and overwrite files on the device.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
