Persistent access via unenforced password changes

Published Apr 23, 2026 · Updated Apr 24, 2026

Credential-change failure in SenseLive X3050 V1.523 allows remote attackers to authenticate with previous or default passwords. After a Config 2.0 factory restore, the backend reports a password update as successful without consistently replacing the stored credential. Exploitation requires network access to the web management interface and knowledge of the prior or factory-default password, permitting continued management access.
