Summary

CVE-2024-46433 is a high-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Tenda W18E Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 42th 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 IA-5 (Authenticator Management) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

CVE-2024-46433 is a default credentials vulnerability (CWE-798) in the Tenda W18E router firmware version V16.01.0.8(1625). It enables unauthenticated remote attackers to access the web management portal using the default "rzadmin" account, which possesses administrative privileges. The issue carries a CVSS v3.1 base score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and was published on 2025-02-10.

An attacker with access to the adjacent network can exploit this vulnerability with low complexity and no required privileges or user interaction. Upon logging in with the default credentials, the attacker gains administrative control over the device, potentially allowing high-impact confidentiality, integrity, and availability compromises, such as modifying configurations, extracting sensitive data, or disrupting network operations.

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.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.

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.

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.

none

Mandating immediate replacement of vendor-supplied default credentials eliminates the use of hard-coded or factory passwords that attackers can trivially obtain from documentation or firmware.
