A researcher at vulnerability and red-team company Rapid7 recently uncovered a pair of risky security bugs in a digital home security product.

The first bug, reported back in May 2021 and dubbed CVE-2021-39276, means that an attacker who knows the email address against which you registered your product can effectively use your email as a password to issue commands to the system, including turning the entire alarm off.

The affected product comes from the company Fortress Security Store, which sells two branded home security setups, the entry-level S03 Wifi Security System, which starts at $130, and the more expensive S6 Titan 3G/4G WiFi Security System, starting at $250.

The intrepid reseacher, Arvind Vishwakarma, acquired an S03 starter system, which includes a control panel, remote control fobs, a door or window sensor, a motion detector, and an indoor siren.

(The company also sells additional fobs and sensors, outdoor sirens, which are presumably louder, and “pet-immune” motion detectors, which we assume are less sensitive than the regular ones.)

Unfortunately, it didn’t take much for Vishwakarma to compromise the system, and figure out how to control it without authorisation, both locally and remotely.

Pwned! The home security system
