TLS private-key disclosure via exposed web file
Published Jul 17, 2022 · Updated Aug 4, 2024
Information disclosure in Reolink E1 Zoom firmware 3.0.0.716 and earlier allows remote attackers to retrieve the camera's TLS private key. The embedded web server places self.key beneath its document root and serves it through the unauthenticated /self.key URI. Network access to the camera is sufficient to obtain the key; subsequent traffic compromise depends on access to encrypted camera traffic.
