检测：

$ env x='(){:;}; echo vulnerable' bash -c "echo this is a test"

 

中招的显示:

vulnerable

this is a test

 

如果是没有问题，则是下面

$ 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
