The ONVIF service on the E3 can be rendered unresponsive by sending malformed or incomplete requests to certain operations.

MEDIUM 6.9EPSS 0.52%

Does this matter?

Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.

Description

The ONVIF service on the E3 can be rendered unresponsive by sending malformed or incomplete requests to certain operations. The affected service stops accepting new connections while the rest of the device continues operating normally, and will recover automatically after a period. This can be triggered repeatedly by any unauthenticated party with network access to the device.
