CVE-2017-12148: Red Hat Ansible Tower

High severity, CVSS 7.2. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Ansible Tower: before 3.1.5 (fixed in 3.1.5); before 3.2.0 (fixed in 3.2.0)
• Red Hat Cloudforms: version 4.5 only
