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

CVE-2026-2616 is a vulnerability involving hard-coded credentials in an unknown function of the Web Management Interface component in Beetel 777VR1 routers, affecting versions up to 01.00.09. 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 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The issue was publicly disclosed on 2026-02-17.

Attackers on the adjacent local network (AV:A) can exploit this vulnerability with low complexity and no required privileges or user interaction. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, potentially allowing full compromise of the device, such as executing arbitrary commands or altering configurations via the exposed credentials in the web interface.

Advisories, including those from VulDB and a public GitHub Gist detailing reproduction steps, recommend modifying configuration settings to mitigate the risk, as no patches are available. The vendor was contacted early but provided no response. The exploit code has been publicly disclosed and may be actively used.

Notable context includes the public availability of the exploit, increasing the likelihood of real-world attacks against unpatched Beetel 777VR1 devices on local networks. No evidence of widespread exploitation or AI/ML relevance is reported.

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.

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.
