    Fortress Wi-Fi Home Security Alarms

    New vulnerabilities have been found in Fortress S03 Wi-Fi Dwelling Safety System that may very well be doubtlessly abused by a malicious get together to achieve unauthorized entry with an intention to change system conduct, together with disarming the gadgets with out the sufferer’s information.

    The 2 unpatched points, tracked beneath the identifiers CVE-2021-39276 (CVSS rating: 5.3) and CVE-2021-39277 (CVSS rating: 5.7), had been found and reported by cybersecurity agency Rapid7 in Could 2021 with a 60-day deadline to repair the weaknesses.

The corporate’s safety and surveillance methods are utilized by “hundreds of shoppers and continued clients,” according to its web site.

    Calling the vulnerabilities “trivially simple to use,” Rapid7 researchers famous CVE-2021-39276 issues an unauthenticated API Entry that allows an attacker in possession of a sufferer’s e-mail handle to question the API to leak the gadget’s Worldwide Cell Gear Identification (IMEI) quantity, which additionally doubles up because the serial quantity. Armed with the gadget’s IMEI quantity and the e-mail handle, the adversary can proceed to make a lot of unauthorized adjustments, corresponding to disabling the alarm system by way of an unauthenticated POST request.

    CVE-2021-39277, alternatively, pertains to an RF Sign replay attack, whereby an absence of ample encryption grants the dangerous actor the flexibility to seize the radio frequency command and management communications over the air utilizing software-defined radio (SDR), and playback the transmission to carry out particular features, corresponding to “arm” and “disarm” operations, on the goal gadget.

    “For CVE-2021-39276, an attacker with the information of a Fortress S03 consumer’s e-mail handle can simply disarm the put in house alarm with out that consumer’s information,” the researchers mentioned in a report shared with The Hacker Information.
