Incorrect permission check for deployment projects (CVE-2017-8907)


Atlassian rates the severity level of this vulnerability as critical, according to the scale published in our Atlassian severity levels. The scale allows us to rank the severity as critical, high, moderate or low.

This is our assessment and you should evaluate its applicability to your own IT environment.



Bamboo did not correctly check if a user creating a deployment project had the edit permission and therefore the rights to do so. An attacker who can login to Bamboo as a user without the edit permission for deployment projects is able to use this vulnerability, provided there is an existing plan with a green build, to create a deployment project and execute arbitrary code on an available Bamboo Agent. By default a local agent is enabled this means that code execution can occur on the system hosting Bamboo as the user running Bamboo.

Versions of Bamboo starting with 5.0.0 before 5.15.7 (the fixed version for 5.15.x) and from 6.0.0 before 6.0.1 (the fixed version for 6.0.x) are affected by this vulnerability. This issue can be tracked here:



Atlassian would like to credit Iordache Cosmin (@inhibitor181) for reporting this issue to us.



We have taken the following steps to address this issue:

  1. Released Bamboo version 6.0.1 that contains a fix for this issue.
  2. Released Bamboo version 5.15.7 that contains a fix for this issue.

What You Need to Do

Atlassian recommends that you upgrade to the latest version. For a full description of the latest version of Bamboo, see the release notes. You can download the latest version of Bamboo from the download centre.
