CVE-2017-12148 Information

Description

A flaw was found in Ansible Tower’s interface before 3.1.5 and 3.2.0 with SCM repositories. If a Tower project (SCM repository) definition does not have the ‘delete before update’ flag set an attacker with commit access to the upstream playbook source repository could create a Trojan playbook that when executed by Tower modifies the checked out SCM repository to add git hooks. These git hooks could in turn cause arbitrary command and code execution as the user Tower runs as.
