Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in the OpenWebif plugin through 1.2.4 for E2 open devices. The saveConfig function of "plugin/controllers/models/config.py" performs an eval() call on the contents of the "key" HTTP GET parameter. This allows an unauthenticated remote attacker to execute arbitrary Python code or OS commands via api/saveconfig.
