CVE-2021-40150

36
FAUCET Score

CVE-2021-40150 is a high-severity information disclosure vulnerability affecting Reolink E1 Zoom cameras running firmware through version 3.0.0.716. An attacker can remotely access sensitive NGINX and FastCGI configuration files by querying publicly accessible URIs on the device's web server. This unauthenticated exposure of configuration data could lead to further compromise, though it does not directly impact integrity or availability. While no active exploitation or public Metasploit modules are reported, Nuclei templates exist, and the vulnerability has a high EPSS score, indicating a higher-than-average likelihood of exploitation.
