Acoustic Technology, Inc. (ATI Systems) created a patch to mitigate improper authentication and missing encryption of sensitive data vulnerabilities in its ATI Emergency Mass Notification Systems, according to a report from ICS-CERT.
Successful exploitation of these remotely exploitable vulnerabilities, discovered by Balint Seeber of Bastille, could trigger false alarms.
The following ATI’s Emergency Mass Notification Systems devices suffer from the vulnerabilities:
In one vulnerability, improper authentication caused by specially crafted malicious radio transmissions may allow an attacker to remotely trigger false alarms.
CVE-2018-8862 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 5.3.
In addition, missing encryption of sensitive data vulnerability caused by specially crafted malicious radio transmissions may allow an attacker to remotely trigger false alarms.
CVE-2018-8864 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 5.3.
The products see use mainly in the commercial facilities, defense industrial base, emergency services, government facilities, nuclear reactors, materials, and waste sectors. It also sees action on a global basis.
No known public exploits specifically target these vulnerabilities. However, an attacker would need high skill level to exploit the vulnerabilities.
ATI has created a patch which adds additional security features to the command packets sent over the radio. ATI is testing this patch, and it will be available upon request. Many systems are engineered to meet specific user needs and users need to make sure any upgrades are appropriate for their systems.
ATI recommends, where feasible, simple voice radios be replaced with digital P-25 (APCO) radios, which provide highly secure encrypted links.
