CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Description
The web server of the E1 Zoom camera through 3.0.0.716 discloses its configuration via the /conf/ directory that is mapped to a publicly accessible path. In this way an attacker can download the entire NGINX/FastCGI configurations by querying the /conf/nginx.conf or /conf/fastcgi.conf URI.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 3.7% probability of exploitation activity in the next 30 days.
