Due to a shared Amazon S3 credential, all users of a certain model of the Guardzilla All-In-One Video Security System can view each other’s videos.
A vulnerability in the Guardzilla All-In-One Video Security System, an IoT-enabled home video surveillance system, lets all users view one another’s saved surveillance footage due to the design and implementation of Amazon S3 credentials inside the camera’s firmware.
Security researchers found the bug (CVE-2018-5560) during an event held by 0DayAllDay and reported it to Rapid7 for coordinated disclosure. Rapid7 published the flaw today, 60 days after it first attempted to contact the vendor. Multiple coordination efforts received no response.
