CVE-2026-23853 is a use of weak credentials vulnerability (CWE-1391) in Dell PowerProtect Data Domain systems running Data Domain Operating System (DD OS). It affects Feature Release versions 7.7.1.0 through 8.5, LTS2025 release versions 8.3.1.0 through 8.3.1.20, and LTS2024 release versions 7.13.1.0 through 7.13.1.50. The vulnerability carries a CVSS v3.1 base score of 8.4 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and was published on 2026-04-17.
An unauthenticated attacker with local access could potentially exploit this vulnerability to gain unauthorized access to the system. Exploitation requires low complexity and no user interaction, enabling high-impact compromise of confidentiality, integrity, and availability.
Dell security advisory DSA-2026-060 addresses this and other vulnerabilities in PowerProtect Data Domain, providing security updates for mitigation.

Mitigating Controls (NIST 800-53 r5) AI
IA-5 directly requires management of authenticator strength, distribution, and replacement, stopping default or guessable credentials from being introduced or used.
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.AA-01's credential issuance and key-management processes directly block most weak/default credential usage, yet leave hard-coded or product-design instances of CWE-1391 only partially addressed.
Password-strength policies in PR.AA-03 directly block weak authenticators, but the control leaves hard-coded/default credentials largely unaddressed.
Hardened baselines and default-setting reviews directly block default/hard-coded creds (mostly), yet leave algorithmic guessing, reuse, and non-config sources of weak credentials untouched (partial).
Training raises password-hygiene awareness and can therefore reduce some weak-credential mistakes, yet supplies no enforcement mechanism and leaves the dominant technical sources of CWE-1391 untouched.
Role-based awareness training can reduce the chance developers or admins introduce weak credentials but supplies no enforcement or verification, leaving the bulk of CWE-1391 risk untouched.
Maintenance/patching can incidentally remove known weak-default creds in updated versions (partial forward) but does nothing to ensure credentials are strong at design, deployment or config time (none reverse).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
Directly requires secure generation, distribution and storage of authentication credentials, eliminating default/hard-coded weak passwords.
Mandates secure authentication mechanisms that preclude use of weak or default credentials.
Secure-coding rules can prohibit hard-coded passwords, yet coverage depends on specific coding standards adopted.
Security testing can discover weak credentials, but does not guarantee they are prevented by design.
Enforces secure baseline configurations that should remove default credentials, yet does not guarantee credential strength.
Restricts privileged accounts but does not explicitly address default or hard-coded credentials for those accounts.
