CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-39462 impacting senselive x3500_firmware. Evaluated with CVSS Base Score of 8.1 (HIGH).

Original NVD Description

Source: NIST NVD
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.
