CVE-2026-24429Network attack vector

Management access via unchanged built-in account password

Published Jan 26, 2026 · Updated Jan 26, 2026

Use of a default password in Tenda W30E V2 firmware 16.01.0.19(5037) and earlier allows remote attackers to access its management interface. A built-in authentication account ships with a predefined password, and initial configuration does not require that password to be changed. Network access to the web-management interface is sufficient to authenticate with the unchanged credentials and obtain the account's management privileges.
