"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.

Hikvision has released updates to mitigate the improper authentication vulnerability in cameras sold through authorized
distributers. Hikvision has not mitigated the password in configuration file vulnerability.

However, Hikvision is aware of so-called “grey market” cameras which are sold via unauthorized channels. These cameras
often use unauthorized firmware created by sources outside of Hikvision. In the case of these “grey market” devices,
updating the firmware may result in converting the camera’s interface back to its original state. Users of “grey market”
cameras who cannot update due to this unauthorized firmware will still be susceptible to these vulnerabilities.

In the Hikvision Unauthorized Distributors Notice, Hikvision encourages users to use devices sold by authorized
distributers rather than so-called “grey market” devices. Hikvision’s Unauthorized Distributors Notice can be found at
the following location:

Hikvision also states that device models and firmware upgrade procedures may differ between regions. These policies will
