Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-22273 is a Use of Default Credentials vulnerability (CWE-1392) affecting the operating system in Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.2.0.0. Published on January 23, 2026, it has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on confidentiality, integrity, and availability.

A low-privileged attacker with remote network access can exploit this vulnerability by leveraging the default credentials. Successful exploitation allows elevation of privileges, potentially granting unauthorized control over the affected systems.

Dell Security Advisory DSA-2026-047 provides details on security updates for Dell ECS and ObjectScale to address this and other vulnerabilities; practitioners should consult https://www.dell.com/support/kbdoc/en-us/000415880/dsa-2026-047-security-update-for-dell-ecs-and-objectscale-multiple-vulnerabilities for patching instructions and mitigation guidance.

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Secure configuration settings establish baselines that prohibit default credentials on system components.

IA-5 Authenticator Management good match

Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.

RA-5 Vulnerability Monitoring and Scanning good match

Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.

AC-2 Account Management partial match

Account management processes include assignment and control of initial account credentials, reducing the chance defaults remain active.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-01 full match
prevents

Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.

PR.AA-01 mostly match
prevents

Credential management processes directly require replacing or disabling default passwords and keys.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.9 Configuration management mostly match
prevents

The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
