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

Severity:
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.


Description:

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
at: https://jira.atlassian.com/browse/BAM-18405 .


Fix:

To address this issue, we've released the following versions containing a fix:

* Bamboo version 5.15.7
* Bamboo version 6.0.1

Remediation:

Upgrade Bamboo to version 6.0.1 or higher.

The vulnerabilities and fix versions are described above. If affected,
you should upgrade to the latest version immediately.

If you are running Bamboo 5.15.x and cannot upgrade to 6.0.1, upgrade
to version 5.15.7.
