Summary
In Weidmueller Industrial WLAN devices in multiple versions an exploitable denial-of-service vulnerability exists in ServiceAgent functionality. A specially crafted packet can cause an integer underflow, triggering a large memcpy that will access unmapped or out-of-bounds memory. An attacker can send this packet while unauthenticated to trigger this vulnerability.
