Red Hat Ansible Automation Platform: remote code execution

A flaw was found in Red Hat Ansible Automation Platform's automation-

controller. The Project scm_url field is not validated against values that

begin with a dash and is stored and passed verbatim to the git SCM module.

Because the module runs git ls-remote with the URL as a positional argument and

without a "--" separator, a git project URL such as "--upload-pack=<command>:x"

is interpreted by git as the --upload-pack option and executed via a shell. A

user with permission to create or modify a project in a single organization can

thereby execute arbitrary commands on the control-plane task pod, with output

reflected through the project update stdout endpoint, leading to cross-tenant

compromise and in-cluster lateral movement
