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.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
