Summary

ESCAM QD-900 WIFI HD cameras contain an unauthenticated configuration disclosure vulnerability in the /web/cgi-bin/hi3510/backup.cgi endpoint. The endpoint allows remote download of a compressed configuration backup without requiring authentication or authorization. The exposed backup can include administrative credentials and other sensitive device settings, enabling an unauthenticated remote attacker to obtain information that may facilitate further compromise of the camera or connected network.
