Vulnerability from github – Published: 2025-11-27 00:30 – Updated: 2025-11-27 00:30

Details

Astak CM-818T3 2.4GHz wireless security surveillance cameras contain an unauthenticated configuration disclosure vulnerability in the /web/cgi-bin/hi3510/backup.cgi endpoint. The endpoint permits remote download of a compressed configuration backup without requiring authentication or authorization. The exposed backup may include administrative credentials and other sensitive device settings, enabling an unauthenticated remote attacker to obtain information that could facilitate further compromise of the camera or connected network.

Severity ?

8.7 (High)


                  
                    CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
