Quick assessment

Affected
AWS aws-tools-for-powershell
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.

在 AWS Tools for PowerShell 5.0.306 之前的版本中，将敏感信息写入日志文件可能存在安全漏洞，允许本地用户从命令输出和日志文件中恢复 IAM 用户的明文 AWS Management Console 密码。 为修复此问题，用户应升级至 5.0.306 或更高版本。升级后，请检查 PowerShell 脚本转录文件（transcripts）和日志存储，查找此前泄露的密码，并对所有受影响的 IAM 控制台密码进行轮换（更换）。
