CVE-2026-24429 is a critical-severity Use of Default Password (CWE-1393) vulnerability in Tenda W30E Firmware. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked at the 30th 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-24429 is a high-severity vulnerability (CVSS v3.1 score of 9.8) in the firmware of the Shenzhen Tenda W30E V2 router, affecting versions up to and including V16.01.0.19(5037). The issue stems from a predefined default password for a built-in authentication account that is not required to be changed during initial configuration, classified under CWE-1393. Published on 2026-01-26, it enables attackers to use these static credentials to access the device's management interface.
The vulnerability can be exploited by any unauthenticated remote attacker over the network (AV:N/AC:L/PR:N/UI:N), requiring no privileges, user interaction, or complex setup. Successful exploitation provides authenticated access to the management interface, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), such as executing arbitrary commands, modifying configurations, or disrupting device operations.
Advisories, including the VulnCheck report at https://www.vulncheck.com/advisories/tenda-w30e-v2-hardcoded-default-password-for-built-in-account, highlight the hardcoded nature of the credentials. Mitigation involves immediately changing the default password on affected devices and checking the Tenda product page at https://www.tendacn.com/product/W30E for firmware updates that may resolve the issue.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Authenticator management requires verification of identity at initial distribution and secure handling that directly stops default passwords from remaining in use.
Configuration settings establish the most restrictive secure baselines, which include changing or disabling default passwords.
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.
Credential management directly requires replacing default passwords with unique, strong credentials.
Hardened configuration baselines explicitly prohibit default passwords, covering most of the weakness but not all identity-management aspects.
Vulnerability scanning will discover default-password instances, enabling remediation, yet does not itself prevent their initial use.
Authentication policies can enforce non-default passwords but do not address the full scope of credential lifecycle.
Authorization policies assume credentials already exist and are not default; least-privilege helps limit impact but does not prevent 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.
Mandates secure handling and change of authentication secrets, directly addressing default passwords.
Configuration management processes typically enforce changing defaults during hardening.
Requires secure authentication mechanisms, which includes replacing or disabling default credentials.
Utility programs often ship with defaults; control requires secure configuration before use.
Privileged accounts must not retain factory passwords, reducing risk of default-credential abuse.
