Jenkins encrypts secrets at rest but keeps the decryption key somewhere on its host.One-way hashes are then out of the picture, what's left is two-way encryption. I did not use the word “secure” anywhere in the introduction because the way any CI server stores credentials, are by nature, insecure.ĬI servers cannot use one-way hashes (like bcrypt) to encode secrets because when requested by the pipeline, those secrets need to be restored into their original form.

What do you do when you join a project and the person with the vital knowledge has long left, and nobody knows how to access that windows 98 machine in production?Įncryption, decryption, Jenkins provides plain text subscription.Įven if you don't need to stealthily obtain the credentials from your own company it is still good to know about the vulnerabilities when using Jenkins. We don't know them they don't know us however, Jenkins doesn't choose sides.

All we need is to have a full picture of the situation. However, we don't judge stuff happens, deadlines must be met, we understand. Sometimes we encounter entities which are, let's say, reluctant to share. The answers you seek, Jenkins shall leak. If you don't want people to poke around, don't give them ANY access to your CI. Giving access to a Jenkins equals a license to view all secrets stored there. There is no need for that we already have the approvals. To make a good first impression ask Jenkins for a confession.īy requesting access, we could be delayed by questions like "why do you need that?" or "I will have to talk with my supervisor first."
If we've been granted full access on paper, then there is no ethical dilemma here. We can speed up things a little bit by poking around in Jenkinses and finding the way in ourselves. It could also be the case where nobody knows how to access the resource. We, of course, can request permission for access, but it can take quite a while.
Sometimes, however, the things we would like to check are, let's say, temporarily out of our reach. Usually, the client provides us full access to the codebase and the infrastructure. To provide the best service as consultants, we often need all the information the client can give us. Jenkins is an easy pick when it comes to intelligence gathering.
