Summary
CVE-2026-39462 is a critical-severity Insufficiently Protected Credentials (CWE-522) vulnerability in Senselive X3500 Firmware. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Remote Services (T1021); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-28 (Protection of Information at Rest) and SC-8 (Transmission Confidentiality and Integrity) — 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-2026-39462 is a vulnerability in the web management interface of the SenseLive X3050 device, stemming from improper handling of credential changes on the backend (CWE-522: Insufficiently Protected Credentials). Password updates are not reliably applied, particularly after a factory restore using the SenseLive Config 2.0 tool. In such cases, the interface may report a successful password change, but the system continues to accept previous or default credentials. This issue persists even after factory resets, as attempted password changes fail to propagate correctly. The vulnerability carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
A remote attacker with network access to the SenseLive X3050 can exploit this vulnerability without privileges or user interaction, though it requires high attack complexity. By leveraging the failure of password changes to take effect—especially post-factory restore—the attacker can authenticate to the web management interface using unchanged previous or default credentials. Successful exploitation grants high-impact access, enabling confidentiality breaches, integrity modifications, and availability disruptions on the affected device.
For mitigation details, refer to CISA ICS Advisory ICSA-26-111-12 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-111-12), the vendor contact page (https://senselive.io/contact), and the associated CSAF document (https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-111-12.json). These resources provide guidance from CISA and SenseLive on addressing the issue.

Vulnerability Data
A vulnerability exists in SenseLive X3050’s web management interface in which password updates are not reliably applied due to improper handling of credential changes on the backend. After the device undergoes a factory restore using the SenseLive Config 2.0 tool,…

the interface may indicate that the password update was successful; however, the system may continue to accept the previous or default credentials, demonstrating that the password-change process is not consistently enforced. Even after a factory reset, attempted password changes may fail to propagate correctly.

Mitigating Controls (NIST 800-53 r5) AI
Protection of information at rest requires encryption or equivalent safeguards for stored credentials.
Transmission confidentiality and integrity enforcement stops credentials from being sent in plaintext or without protection.
Authenticator management requires secure generation, storage, and distribution of credentials, directly stopping insecure methods.
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 practices directly reduce insecure storage/transmission but do not guarantee encryption or transport protection.
Authentication policies can enforce stronger credential handling yet address only verification, not storage or transit protection.
Protecting identity assertions covers conveyance of credentials but is narrower than full credential lifecycle protection.
Encrypting data-at-rest fully prevents insecure credential storage while only partially satisfying the broader data-protection outcome.
Encrypting data-in-transit fully prevents interception of credentials in motion while only partially satisfying the broader data-protection outcome.
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.
Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.
Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.
Contractual clauses that survive termination help ensure that credentials and other secrets are not retained or misused after employment ends.
Regular reminders about password security and personal accountability make users less likely to store or transmit credentials in cleartext or other unprotected forms.
By requiring signatories to protect credentials and other authentication material under the same confidentiality terms, the control discourages the mishandling or exposure of credentials that could lead to unauthorized account access.
Requiring logical controls such as passwords or PINs on idle devices and the use of remote lockout mechanisms protects credentials and other sensitive material from offline extraction.
