The XSS payload triggers when accessing the "/apps" path (if an application was previously added).  **Additional PoC:** 1. In the "Display Name" field, enter the following payload: `"><img src onerror="alert(1)">`.  2. The XSS vulnerability is triggered when accessing the "/ports" path, and the payload executes when hovering over the modified value in the "Port" field.  - on `/device/$DEVICE_ID/ports/arp` path:  - on `/device/$DEVICE_ID/logs` path:  - on `/search/search=arp/` path:  **Impact:** Execution of Malicious Code
