tari updated AMBARI-26059:
--------------------------
Description:
Apache Ambari version: 2.1.0-rc0 to 2.8.0-rc1 allows a malicious authenticated
user to execute arbitrary command remotely. Just like `touch /tmp/pwn` can
execute any command of the below screenshot.

I think we should not use `sh -c` or `cmd /c` to execute shell command which
lead to command injection.
To fix this issue, that's two-step we should follow:
# Replace `sh -c` or `cmd /c` to parameterized command execution
# The above fix the way using some special char like `$..... to inject evil
command to `script` var, but it can't prevent the path traversal to execute
evil command, if any input content in `properties` contain `..` we should block
it and return failed tip to front end
I have emailed the complete reproduction steps to [~brahmareddy]. . You can
forward it to him if necessary.
