Exploitation Conditions

Exploitation requires that (1) the attacker already has access to the host server operating system running Armatura One, and (2) the database superuser's vendor-defined default password has not been changed from its shipped value since installation. The vulnerability is fully mitigated on deployments where an administrator has reset the superuser password. Limiting factors: no network attack path (AV:L), so it is not remotely exploitable over a network, and it depends on the insecure default configuration persisting post-install; it does not require user interaction or prior application-level authentication once OS access is obtained.

Impact

This is a hardcoded/vendor-default credentials flaw (CWE-798) in Armatura One where the database superuser is assigned a fixed, vendor-defined password at installation. The vendor-supplied CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:N) scores 8.6 largely because of full VC:H/VI:H/VA:H impact to the database, but the Attack Vector is Local - the description explicitly requires 'access to the server operating system' before the static password can be used, which materially lowers real-world risk versus a network-reachable flaw. There is no EPSS score, no CISA KEV listing, and no public exploit code in the provided intelligence, so exploitation status is 'no public exploit identified at time of analysis.' The PR:N rating reflects that no application credentials are needed once the known password is used, but it understates the practical precondition of obtaining OS-level access to the host. Net: a genuinely serious post-access privilege/data-compromise issue for the database, but not an internet-facing mass-exploitation priority - treat as high-priority hardening on exposed/shared hosts rather than an emergency network patch. Note signal gap: no EPSS/KEV/POC data was supplied, so exploitation likelihood cannot be quantitatively corroborated.

Exploit ScenarioDerived

An attacker who has already gained access to the server operating system hosting Armatura One (e.g., a local user, a low-privileged service account, or via another foothold) connects to the local database using the publicly/vendor-known default superuser password that was never changed. With superuser access they read, modify, or destroy all access-control and biometric data. No public exploit code is required - only knowledge of the fixed password and the AV:L/AC:L conditions make this straightforward once OS access exists.

AnalysisAIv2 – Oct 02, 2026

Armatura One ships with a fixed, vendor-defined password assigned to its database superuser account during database initialization, so it is identical across installations unless an administrator has changed it. Anyone who already has access to the underlying host operating system and knows this value can authenticate to the database as the superuser on any deployment where the default has not been rotated. The flaw is rated 8.6 under CVSS 4.0 (assessed as CVSS 3.1 AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), requires local OS-level access rather than a network path, requires no user interaction or application-level authentication, and there is no public exploit identified at time of analysis; exploitation is fully prevented on systems where the superuser password has been reset.

v1 Oct 02, 2026 - 22:17 CVSS 8.4

Armatura One (and its Armatura One (USA) variant) assigns a fixed, vendor-defined password to the database superuser account during installation, so anyone who has access to the underlying server operating system and knows that constant value can authenticate as the database superuser on any deployment where the credential was never rotated. Because the account is a full superuser and the credential is hard-coded (CWE-798), successful use yields high confidentiality, integrity, and availability impact - assessed as CVSS 3.1 base 8.4 with the vector AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. Exploitation is gated by two prerequisites: local access to the server OS and an unchanged default password, and no public exploit code has been identified at time of analysis (the flaw is not listed in CISA KEV); the weakness is effectively self-mitigating anywhere administrators rotated the database superuser password after deployment.

RemediationAI

The primary fix is to change the database superuser password from the vendor-defined default immediately after installation and on every existing deployment - verify the change took effect by testing the old credential, and rotate it again if any installation predates the patch cycle. No vendor-released patch version is identified in the available intelligence, and the CISA ICS advisory ICSA-26-274-01 (also available as CSAF JSON at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-274-01.json) is the authoritative source for any update; consult it and the vendor directly before assuming a firmware or software upgrade resolves the hard-coded credential. Compensating controls, and their trade-offs: restrict interactive and remote logon to the Armatura One host to a minimal set of trusted administrators (reduces the pool of attackers who can satisfy the OS-access prerequisite, but does not help if an authorized admin account is compromised and complicates break-glass access), remove or disable the default superuser account in favor of a uniquely named administrative account with a strong generated password (breaks scripts and integrations that reference the original account name, so inventory dependencies first), enforce host-based firewall rules or network segmentation so database ports are reachable only from the application itself (may break remote administration tooling and backup jobs), and enable database and OS authentication logging with alerting on logins as the superuser outside change windows (adds log volume and requires tuning to avoid noise). Because exploitation requires local OS access, hardening the host - patching, least-privilege accounts, and disabling unused services - directly shrinks the exposure window, but none of these substitute for rotating the credential.

Technical ContextAI · show details

This is a use of hard-coded credentials weakness (CWE-798) rooted in Armatura One's database initialization routine, which provisions the database superuser with a static, vendor-defined password at creation time instead of generating a unique random secret per installation. Because the credential is baked into the deployment process rather than derived per-site, knowledge of the value combined with local access to the server hosting Armatura One yields full superuser control of the database - read/write/delete of all data, schema and configuration modification, and potentially further pivot into other components that trust the database. The CPE data identifies both Armatura LLC products 'armatura_one' and 'armatura_one_(usa)' as affected with wildcarded version fields, indicating the issue is systemic to the product line rather than tied to a single release. The CVSS 4.0 vector shows AT:N (no attack requirements beyond prerequisites) and PR:N (no privileges required), consistent with the assessment that once OS access exists no further authentication barrier remains; however, the AV:L local attack vector means it is not exploitable remotely over a network, and the assessment explicitly notes the flaw is not present once an administrator has reset the superuser password.

DescriptionCVE.org

Armatura One's database initialization routine assigns a fixed, vendor-defined password to the database superuser account at creation time, rather than generating a unique password per installation. An individual with access to the server operating system and knowledge of this value can authenticate as the database superuser on a deployment where it has not been changed.

Executive ViewAI

Why It Matters

Armatura One deployments may be exposed to a high-severity database compromise risk because the database superuser account is initialized with a fixed, vendor-defined password that remains unchanged unless administrators rotate it. Any attacker with local operating system access can use this default credential to gain full superuser control of the database, affecting confidentiality, integrity, and availability of application and business data. Leadership should prioritize identifying affected deployments and enforcing immediate password rotation, especially since no vendor-released patch is identified at time of analysis and no public exploit identified at time of analysis.

Business Impact: High
Compensating Controls

Rotate the database superuser password from the vendor default; restrict local OS access and require least privilege and MFA for administrators; monitor database authentication logs; deploy host-based monitoring for suspicious superuser activity.
