CVE-2025-40537, published on 2026-01-28, is a hardcoded credentials vulnerability (CWE-798) affecting SolarWinds Web Help Desk. The issue could allow access to administrative functions under certain situations. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating network accessibility, high attack complexity, low privilege requirements, no user interaction, unchanged scope, and high impacts on confidentiality, integrity, and availability.

An authenticated attacker with low privileges can exploit this vulnerability over the network if they satisfy the high attack complexity conditions. Successful exploitation enables access to administrative functions, resulting in high-level compromise of confidentiality, integrity, and availability.

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.
