Summary
CVE-2025-5124 is a critical-severity Use of Default Credentials (CWE-1392) vulnerability. Its CVSS base score is 9.2 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. It is recommended to change the configuration settings. The vendor was contacted early about this issue. They confirmed the existence but pointed out that they "have published the 'Hardening Guide' on the Web from July 2018 to January 2025 and have thoroughly informed customers of the recommendation to change their initial passwords".

V13.2.1
Mitigating Controls (NIST 800-53 r5) AI
Secure configuration settings establish baselines that prohibit default credentials on system components.
Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.
Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.
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.
Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.
Credential management processes directly require replacing or disabling default passwords and keys.
Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.
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.
The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
