Description

Tapo C120 v1 and C200 v5 contain a NULL pointer dereference in the HTTPS onboarding connect request parser.  The interface is reachable without authentication after initial setup and does not validate that a password field is present for certain authentication and encryption parameter combinations, allowing a malformed request from the same local network to crash the HTTPS service  Successful exploitation may temporarily make HTTPS management functions unavailable. Repeated malformed requests may sustain the denial-of-service condition, and recovery may in some cases require a device reboot.
