Description

OpenBK7231T's CHANNEL_SetLabel() (src/cmnds/cmd_channels.c) stores channel labels received via the MQTT SetChannelLabel command using strdup() with no HTML sanitization. CHANNEL_GetLabel() returns these labels unsanitized, and they are rendered via hprintf255() at 15+ locations in src/httpserver/http_fns.c with no HTML encoding. An attacker with MQTT broker access (commonly unauthenticated in real deployments) can set a channel label containing a <script> payload that executes when any user views the device's web panel.
