Title:
PowerVM config drive path is not secure
Status in OpenStack Compute (nova):
In Progress
Status in nova-powervm:
New
Bug description:
This report is based on the Bandit scanner results and code review.
1)
On https://git.openstack.org/cgit/openstack/nova/tree/nova/virt/powervm/media.py?h=refs/heads/master#n44
43 _VOPT_SIZE_GB = 1
44 _VOPT_TMPDIR = '/tmp/cfgdrv/'
45
We have hardcoded tmp dir that could be cleaned up after compute node reboot.
As mentioned in todo it might be good to use conf option.
2)
On https://git.openstack.org/cgit/openstack/nova/tree/nova/virt/powervm/media.py?h=refs/heads/master#n116
Predictable file name based on a user input is used:
116 file_name = pvm_util.sanitize_file_name_for_api(
117 instance.name, prefix='cfg_', suffix='.iso',
118 max_len=pvm_const.MaxLen.VOPT_NAME)
Probably we could use instance.uuid for that.
