Patch Name
Siemens SICAM RTU设备存在拒绝服务漏洞的补丁
Patch Description
Siemens sm-2558和sm-2556通信模块是LAN/WAN的快速以太网通信接口单元。 Siemens SICAM RTU设备存在拒绝服务漏洞。由于特制的数据包发送到2404/TCP端口可能会导致受影响的设备进入缺陷模式，远程攻击者利用漏洞可发起拒绝服务攻击。目前，供应商发布了安全公告及相关补丁信息，修复了此漏洞。
Formal description

SM-2556模块厂商尚未提供补丁，可参考如下临时解决办法： 1、使用防火墙或IPSec功能禁止sm-2558模块访问2404/TCP端口； 2、在可信任的网络运行RTU。

SM-2558模块可升级至ETA4 revision 08，参考如下链接： http://w3.siemens.com/smartgrid/global/en/products-systems-solutions/substation-automation/substation-automation/Pages/Overview.aspx
