CVE-2026-1610 is a vulnerability involving hard-coded credentials in the Telnet Service of Tenda AX12 Pro V2 running firmware version 16.03.49.24_cn. The issue affects an unknown functionality within this component, classified under CWE-259 (Use of Hard-coded Password) and CWE-798 (Use of Hard-coded Credentials). It carries a CVSS v3.1 base score of 8.1 (High), reflecting network accessibility (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability was published on 2026-01-29.

Attackers can exploit this remotely by manipulating the Telnet Service using the hard-coded credentials, though it requires a high degree of complexity and is known to be difficult to execute. No authentication or user interaction is needed, allowing unauthenticated remote actors to potentially gain high-level access. Successful exploitation could result in unauthorized disclosure of sensitive data, modification of system resources, and disruption of service availability.

Advisories and details are documented on VulDB (ctiid.343378, id.343378, submit.740766) and a GitHub issue at QIU-DIE/CVE/issues/49, with the vendor site at tenda.com.cn potentially providing further guidance. No specific patches or mitigations are detailed in the available information.

The exploit has been made public and could be used, increasing the risk for exposed Tenda AX12 Pro V2 devices on the specified firmware.

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.
