Quick assessment
Affected
n/a SICK MSC800
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Sick MSC800是德国西克（Sick）公司的一款可编程逻辑控制器（PLC）。 Sick MSC800 4.15之前存在安全漏洞，该漏洞允许攻击者预测TCP初始序列号。当 TCP 序列是可预测的时，攻击者可以发送伪装成来自受信任计算机的数据包。这些伪造的数据包可能会危及 MSC800 上的服务。

Vulnerability Description
The vulnerability in the MSC800 in all versions before 4.15 allows for an attacker to predict the TCP initial sequence number. When the TCP sequence is predictable, an attacker can send packets that are forged to appear to come from a trusted computer. These forged packets could compromise services on the MSC800. SICK has released a new firmware version of the SICK MSC800 and recommends updating to the newest version.
