CVE-2020-10755

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. Source: OpenStack project

CVE-2020-10755 has a CVSS score of 6.5 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.1.0, 15.2.0, 16.1.0, 2.8.6, 2.10.4, 3.0.2); upgrading removes the vulnerable code path.

1. What is CVE-2020-10755? CVE-2020-10755 is a high-severity security vulnerability in cinder (pip), affecting versions >= 14.0.0, < 14.1.0. It is fixed in 14.1.0, 15.2.0, 16.1.0, 2.8.6, 2.10.4, 3.0.2.
2. How severe is CVE-2020-10755? CVE-2020-10755 has a CVSS score of 6.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2020-10755?
   • cinder (pip) (versions >= 14.0.0, < 14.1.0)
   • os-brick (pip) (versions >= 2.8.0, < 2.8.6)
4. Is there a fix for CVE-2020-10755? Yes. CVE-2020-10755 is fixed in 14.1.0, 15.2.0, 16.1.0, 2.8.6, 2.10.4, 3.0.2. Upgrade to this version or later.
5. Is CVE-2020-10755 exploitable, and should I be worried? Whether CVE-2020-10755 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2020-10755 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2020-10755?
   • Upgrade cinder to 14.1.0 or later
   • Upgrade cinder to 15.2.0 or later
   • Upgrade cinder to 16.1.0 or later
   • Upgrade os-brick to 2.8.6 or later
   • Upgrade os-brick to 2.10.4 or later
   • Upgrade os-brick to 3.0.2 or later
