ICS Advisory Armatura LLC Armatura One Release DateOctober 01, 2026 Alert CodeICSA-26-274-01 Related topics: Industrial Control System Vulnerabilities , Industrial Control Systems View CSAF Summary Successful exploitation of these vulnerabilities could allow an attacker to gain unauthorized access to the database, execute arbitrary code on the host with the highest level of privilege, or gain control of the physical access-control system. The following versions of Armatura LLC Armatura One are affected: Armatura One <4.7.2 (CVE-2023-46604, CVE-2026-94591, CVE-2026-94592, CVE-2026-94593, CVE-2026-94594) Armatura One (USA) <4.6.1 (CVE-2023-46604, CVE-2026-94591, CVE-2026-94592, CVE-2026-94593, CVE-2026-94594) CVSS Vendor Equipment Vulnerabilities v3 9.8 Armatura LLC Armatura LLC Armatura One Deserialization of Untrusted Data, Use of Hard-coded Cryptographic Key, Use of Hard-coded Credentials, Insertion of Sensitive Information into Log File Background Critical Infrastructure Sectors: Communications, Critical Manufacturing, Energy, Transportation Systems Countries/Areas Deployed: Worldwide Company Headquarters Location: United States Vulnerabilities Expand All + CVE-2023-46604 Armatura One embeds Apache ActiveMQ, exposing its OpenWire protocol listener on the network by default. This embedded version is affected by CVE-2023-46604, a deserialization flaw in the OpenWire marshaller that allows an unauthenticated network attacker to trigger deserialization of an arbitrary object graph before authentication is checked. This can result in arbitrary code execution with the highest level of privilege on the host operating system.

The encryption key and initialization vector are fixed values embedded in the software itself and are identical across every installation. An attacker with a copy of the installation package can recover this key and initialization vector, and can then decrypt the stored credentials of any specific installation to which the attacker separately obtains the encrypted configuration file.
