What it is

Sunhillo SureLine before 9.1.5 contains a path traversal vulnerability in the radarUpdater.cgi endpoint that allows unauthenticated remote attackers to read arbitrary files with root privileges due to missing authentication checks and insufficient sanitization of the filename parameter. Attackers can use directory traversal sequences to access sensitive files such as /etc/shadow, the web user database, the root SSH private key, and the device's TLS private key, leading to full system compromise.
