- 漏洞描述

Beck's IPC GmbH IPC@Chip Telnet Service contains a flaw that may allow a remote denial of service. The issue is triggered due to the application allowing only one session at a time and failing to disconnect that session after an unsuccessful login, which may allow a remote attacker to connect to the Telnet service indefinitely and prevent access for any other legitimate users resulting in a loss of availability.
