CVE-2017-8907 Missing authorization in Atlassian Bamboo

What is CVE-2017-8907?

CVE-2017-8907 is a high-severity missing authorization vulnerability in Atlassian Bamboo, published on 14 Jun 2017. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

Atlassian Bamboo 5.x before 5.15.7 and 6.x before 6.0.1 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.

Weakness: CWE-863
