Title:
stack_create 500 Error with non-string stack_name
Status in heat:
In Progress
Status in OpenStack Security Advisory:
Won't Fix
Bug description:
This issue is being treated as a potential security risk under
embargo. Please do not make any public mention of embargoed (private)
security vulnerabilities before their coordinated publication by the
OpenStack Vulnerability Management Team in the form of an official
OpenStack Security Advisory. This includes discussion of the bug or
associated fixes in public forums such as mailing lists, code review
systems and bug trackers. Please also avoid private disclosure to
other individuals not already approved for access to this information,
and provide this same reminder to those who are made aware of the
issue prior to publication. All discussion should remain confined to
this private bug report, and any proposed fixes should be added to the
bug as attachments.
When sending a stack create request using the REST API through curl
with the stack_name parameter set to either a list, or a dictionary a
Server Error occurs.
The major problem with this is that when this occurs the response of
the request will show what database backend the cloud is utilising
whether it be MySQL, or PostgreSQL. This information could be used by
a malicious user to exploit the databases. Additionally to the
database engine being known, the query itself is also printed in the
response.
This occurs regardless of the level of logging being set for the heat
service.
This has been seen in the master branch as of 12/01/2016.
I have attached the response of a request with a Traceback.
The data being sent is the following:
{
"files": {},
"disable_rollback": true,
"parameters": {
"flavor": "m1.tiny"
},
"stack_name": {"test": "sample"},
"template": {
"heat_template_version": "2013-05-23",
"description": "Simple template to test heat commands",
"parameters": {
"flavor": {
"default": "m1.tiny",
"type": "string"
}
},
"resources": {
"hello_world": {
"type": "OS::Nova::Server",
