An issue was discovered on Gemtek WRTM-127ACN 01.01.02.141 and WRTM-127x9 01.01.02.127 devices. The Monitor Diagnostic network page allows an authenticated attacker to execute a command directly on the target machine. Commands are executed as the root user (uid 0). (Even if a login is required, most routers are left with default credentials.)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
