Affected devices do not properly validate input during the TLS certificate upload process of the web service. This could allow an authenticated remote attacker to trigger a device crash and reboot, leading to a temporary Denial of Service 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.
