Summary
An issue was discovered on Victure WR1200 devices through 1.0.3. The root SSH password never gets updated from its default value of admin. This enables an attacker to gain control of the device through SSH (regardless of whether the admin password was changed on the web interface).
Exploit prediction
0.39% chance of exploitation in the next 30 days, higher than 33% of all scored CVEs (FIRST EPSS, 2026-11-08).
