Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ScadaLTS 2.8.1-release-candidate build 0 存在一个经身份验证的远程代码执行漏洞，其根源在于脚本沙箱被绕过。 具体而言，DWR 框架中的 "DataSourceEditDwr" 类暴露了 "validateScript" 方法，该方法会通过 Rhino 脚本引擎编译并执行由攻击者提供的 JavaScript 代码。由于该方法未设置任何权限校验，拥有低权限账户访问权限的攻击者可以利用 DWR 路由绕过机制来滥用此缺陷，从而在服务器上执行任意代码。
