Potential Security Impact: Remote Access Restriction Bypass, Unauthorized Access
Source: Hewlett Packard Enterprise, HPE Product Security Response Team
Potential vulnerabilities have been identified in HPE Helion OpenStack Glance. The vulnerabilities can be remotely exploited to allow access restriction bypass and unauthorized access.
Note: A malicious tenant is able to reuse deleted Glance image IDs to share malicious images with other tenants in a manner that is undetectable to the victim tenant if the Helion OpenStack administrators have both:
- Edited the policy.json file to allow non-admin tenants to share images with other tenants or edited policy.json to allow non-admin tenants to create public images.
- Deleted image IDs from the Glance database, either manually or using the purge tool ("glance-manage db purge").
Further details are available in OSSN-0075 here: https://wiki.openstack.org/wiki/OSSN/OSSN-0075
SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
- HPE Helion CloudSystem all
- HPE Helion OpenStack all
V3 Base Score
V2 Base Score
HPE has provided the following mitigation instructions for HPE Helion OpenStack Glance:
- This procedure ensures that images shared between two tenants who trust each other are not maliciously replaced by a malicious tenant reusing a deleted image ID. Perform the following action:
- The admin should update the policy.json file so that only admins can deactivate/reactivate images: "deactivate": "role:admin", "reactivate": "role:admin",
- All public or shared images should be quarantined by marking them as deactivated using the Glance API.
- The admin should inspect all public/shared images to see if they have been replaced by malicious images.
- Any images which cannot be confirmed to be non-malicious should be left deactivated.
Images which can be confirmed to be non-malicious images can be reactivated using the Glance API.
- Note: Images can be confirmed to be non-malicious for example by examining the Glance logs or backup Glance databases to show that the image ID has not been recycled.
