GoCD is an open-source tool which is used in software development to help teams and organisations automate the continuous delivery (CD) of software.
GoCD has a vulnerability that lets unauthenticated attackers leak highly sensitive information from a vulnerable GoCD Server instance.
By sending a specially crafted request it is possible to read the contents of the /etc/passwd file of a GoCD server. All requests that begin with /add-on are not authenticated and let through.
By turning this vulnerability into a traffic file and matching rule, we are able to detect attempts to leak sensitive information.
Idappcom has created signature 8021991 along with a traffic file.
