CVE-2019-5148

An exploitable denial-of-service vulnerability exists in ServiceAgent functionality of the Moxa AWK-3131A, firmware version 1.13. 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.
