Script task in Bamboo

[Karthikeyan Kulasekaran]

We are setting up Bamboo in our company, We foresee a risk in Script task. This task gives a privileged to delete what ever folder in the server . How to over come this

Example : We have installed Bamboo in Linux server under /usr/local/bamboo . With Script task defined in a plan can delete this folder

Bamboo is an application that runs stuff that users want it to run. Malicious commands can be run in a multiple ways because almost every build tool allows you to run some shell commands (maven, ant, grails). If you really don't trust your users then as Mike and Daniel proposed:

• use only remote agents
• run remote agents on non-privileged accounts

This way you'll limit your potential damage to the single agent.

Set up the agent to run as a non-privileged user. It's the nature of build servers. Doesn't matter if it's script. You have the same issue with ant, maven or any other build scripts.

You can lock down the permissions where the application installation is done and only allow the bamboo_home dir opened up for the user to write to. If you really want to protect yourself - don't use local agents. Then run the remote agents as non privileged users. That way if somebody does a rm -rf it would only be able to hurt that one agent.

I believe that applies to agents only.

And even there I don't really see a problem. The person who writes the task anyway often needs admin access on agents.

But I aggree, there should be some optional protection.

Btw, the permissions depend on the account the agent or server runs under.
