Summary

CVE-2023-43844 is a high-severity Use of Default Credentials (CWE-1392) vulnerability in Aten Pe6208 Firmware. Its CVSS base score is 8.0 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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.

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.AA-01 partial match
blocks

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

PR.AA-03 partial match
blocks

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

PR.PS-01 partial match
blocks

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

A.8.26 Application security requirements partial match

A.8.28 Secure coding partial match

A.8.9 Configuration management partial match
blocks

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