CVE-2026-35905Public exploitNetwork attack vector

Root access via hard-coded superadmin credentials

Published Jun 4, 2026 · Updated Jun 4, 2026

Hard-coded credentials in T3 Technology T625Pro 1.0.07, T6825G 1.0.03, and T7281 1.0.03 allow remote attackers to gain root access. The firmware stores shared, unchangeable superadmin passwords in its authentication data and accepts them for Telnet and the web management interface. Network access to an enabled management service is required; Telnet remains usable after provisioning, while web access is limited to the pre-provisioning state.
