Vulnerability Spotlight: EIP Stack Group OpENer open to two remote code execution vulnerabilities

Summary: Cisco Talos discovered three vulnerabilities in EIP Stack Group OpENer, an Ethernet/IP stack for I/O adapter devices, two of which - TALOS-2022-1662 (CVE-2022-43605) and TALOS-2022-1661 (CVE-2022-43604) - carry a maximum CVSS score of 10 out of 10. Crafted Ethernet/IP requests to two functions can cause an out-of-bounds write leading to a server crash or remote code execution, while TALOS-2022-1663 (CVE-2022-43606) can trigger a null pointer use and crash the server.
What's compelling: A CVSS 10 out of 10 on an industrial Ethernet/IP stack means an unauthenticated request over the network can potentially hand an attacker code execution on the adapter, and Talos confirmed the exploit against development commit 58ee13c.
