An out-of-bounds write vulnerability exists in the SetAttributeList attribute_count_request functionality of EIP Stack Group OpENer development commit 58ee13c. A specially crafted EtherNet/IP request can lead to an out of bounds write, potentially causing the server to crash or allow for remote code execution. An attacker can send a series of EtherNet/IP requests to trigger this vulnerability.
