Summary

CVE-2025-8730 is a high-severity Use of Hard-coded Password (CWE-259) vulnerability. Its CVSS base score is 8.9 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked in the top 13% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

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

CVE-2025-8730 affects the web interface component of Belkin F9K1009 and F9K1010 routers running firmware versions 2.00.04 and 2.00.09. The issue stems from hard-coded credentials, assigned CWE-259 and CWE-798, and carries a CVSS 4.0 score of 8.9 reflecting network-accessible attack conditions with high impact on confidentiality, integrity, and availability.

An unauthenticated remote attacker can exploit the embedded credentials to obtain administrative access to the device. Public proof-of-concept material has been released detailing the flaw for both models, enabling potential full device compromise without requiring user interaction or elevated privileges.

The vendor was notified prior to disclosure but provided no response or patch. Available references consist of technical write-ups on VulDB and GitHub repositories containing exploit details, with no mitigation steps or firmware updates referenced.

The associated EPSS score remains flat at 0.4511 with no material rise observed after publication.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Authenticator management requires secure distribution and handling of credentials, structurally discouraging hard-coded values.

Cryptographic key management mandates proper establishment and handling instead of embedding keys in code.

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-06 mostly match
prevents

Secure SDLC practices directly prohibit embedding credentials in source code or binaries.

PR.AA-01 partial match
prevents

PR.AA-01's credential/key-management processes can reduce the incentive to embed secrets but do not address or detect hard-coded values in source code, so the weakness remains fully possible.

PR.AA-02 none match
prevents

PR.AA-02 addresses human identity proofing and per-person credential issuance at enrollment; it has no bearing on whether developers embed static credentials in software.

PR.DS-01 none match
prevents

PR.DS-01 addresses encryption and integrity of stored data but never touches credential or key management practices, so it neither prevents hard-coded credentials nor removes any of their risk.

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.

prevents

Education on secure configuration practices discourages technical staff from embedding or relying on hard-coded credentials in systems and applications.

mitigates

Secure key-generation, distribution and storage procedures reduce the likelihood that hard-coded or default cryptographic keys will be introduced or left unprotected.

prevents

Explicit prohibition of hard-coded passwords and unauthenticated external services stops credentials from being embedded directly in source code.

prevents

Contractual requirements for secure coding practices and evidence of testing make it less likely that hard-coded credentials will be introduced or remain undetected in delivered code.

none

Requiring independent oversight and timely disabling of non-human identities makes it harder for hard-coded or long-lived credentials to remain exploitable.

prevents

Requiring users to change temporary or default passwords at first use stops the continued existence of hard-coded or guessable passwords that are shipped with the product.
