漏洞分析
组件介绍
PowerShell 是一种现代命令 shell，包含其他流行 shell 的最佳功能。与大多数只接受和返回文本的 shell 不同，PowerShell 接受并返回 .NET 对象, 是一个跨平台的任务自动化解决方案, 同时支持连接到远程计算机以执行特定的系统命令。
漏洞简介
近日，深信服安全团队监测到一则Powershell组件存在远程代码执行漏洞的信息，漏洞编号：CVE-2022-41076，漏洞威胁等级：高危，漏洞命名：Tabshell。
该漏洞是由于Powershell提供的Powershell Remoting运行环境对用户输入验证不足, 攻击者可利用该漏洞在获得权限的情况下，构造特殊的恶意数据来逃逸限制环境并执行任意的Powershell命令，最终获取服务器最高权限。
