CVE-2024-45166Public exploitNetwork attack vector

Service interruption via fifth unauthenticated login

Published Aug 22, 2024 · Updated Aug 22, 2024

Memory corruption in UCI Software GmbH UCI IDOL 2 through 2.12 allows remote attackers to interrupt the service via repeated logins. Login processing improperly validates and deserializes network input without enforcing memory-buffer bounds, causing an access violation and EIP overwrite after five logins. No credentials or user interaction are required; the demonstrated outcome is service interruption, while code execution remains unconfirmed.
