New vulnerabilities have been discovered in Fortress S03 Wi-Fi Home Security System that could be potentially abused by a malicious party to gain unauthorized access with an aim to alter system behavior, including disarming the devices without the victim's knowledge.

The two unpatched issues, tracked under the identifiers CVE-2021-39276 (CVSS score: 5.3) and CVE-2021-39277 (CVSS score: 5.7), were discovered and reported by cybersecurity firm Rapid7 in May 2021 with a 60-day deadline to fix the weaknesses.

The Fortress S03 Wi-Fi Home Security System is a do-it-yourself (DIY) alarm system that enables users to secure their homes and small businesses from burglars, fires, gas leaks, and water leaks by leveraging Wi-Fi and RFID technology for keyless entry. The company's security and surveillance systems are used by "thousands of clients and continued customers," according to its website.

Calling the vulnerabilities "trivially easy to exploit," Rapid7 researchers noted CVE-2021-39276 concerns an unauthenticated API Access that enables an attacker in possession of a victim's email address to query the API to leak the device's International Mobile Equipment Identity (IMEI) number, which also doubles up as the serial number. Armed with the device's IMEI number and the email address, the adversary can proceed to make a number of unauthorized changes, such as disabling the alarm system via an unauthenticated POST request.
