# CVE-2020-10755: Openstack cinder Improper handling of ScaleIO backend credentials > Attackers can retrieve backend storage credentials via API calls, allowing unauthorized access to other users' volumes and management APIs. - **Severity:** Medium 6.5 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 10 Jun 2020 - **Updated:** 4 Aug 2024 - **Also known as:** DEBIAN-CVE-2020-10755, GHSA-v3m2-pg96-w33m, PYSEC-2020-228, PYSEC-2026-891, RHSA-2020:4283, RHSA-2020:4391, UBUNTU-CVE-2020-10755, USN-4420-1 ## What is CVE-2020-10755? CVE-2020-10755 is a medium-severity vulnerability in Canonical Ubuntu Linux, published on 10 Jun 2020. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description An insecure-credentials flaw was found in all openstack-cinder versions before openstack-cinder 14.1.0, all openstack-cinder 15.x.x versions before openstack-cinder 15.2.0 and all openstack-cinder 16.x.x versions before openstack-cinder 16.1.0. When using openstack-cinder with the Dell EMC ScaleIO or VxFlex OS backend storage driver, credentials for the entire backend are exposed in the ``connection_info`` element in all Block Storage v3 Attachments API calls containing that element. This flaw enables an end-user to create a volume, make an API call to show the attachment detail information, and retrieve a username and password that may be used to connect to another user's volume. Additionally, these credentials are valid for the ScaleIO or VxFlex OS Management API, should an attacker discover the Management API endpoint.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
