Recently, a media reported that some historical versions of Hikvision products were impacted by CVE-2022-2472. To be clear, the issues indicated in the report have all been fixed in new versions.

Hikvision constantly releases software updates to solve new security problems and improve its product security. Firmware packages carry a digital signature to verify the source and integrity of the update package, and to prevent the device from being installed with illegal firmware updates. In addition, Hikvision has adopted an anti-downgrade mechanism to prevent the device from being downgraded to an earlier version with potential security risks.

As always, we strongly encourage users to update their devices to the latest firmware as soon as possible.
