如果你是 Linux 系統的管理者,可以測試看看用這個指令來看系統有沒有漏洞。 在 shell 中輸入
env x=’() { :;}; echo vulnerable’ bash -c “echo this is a test" vulnerable this is a test
如果是「Xthis is a test」就是系統還有漏洞,需儘快更新。 如果是「bash: warning: x: ignoring function definition attempt」,就沒有關係了。
env x=’() { :;}; echo vulnerable’ bash -c “echo this is a test" bash: warning: x: ignoring function definition attempt bash: error importing function definition for `x’ this is a test
