A use-of-uninitialized-pointer vulnerability exists in the Forward Open connection_management_entry functionality of EIP Stack Group OpENer development commit 58ee13c. A specially-crafted EtherNet/IP request can lead to use of a null pointer, causing the server to crash. An attacker can send a series of EtherNet/IP requests to trigger this vulnerability.
