CWEhttps://cwe.mitre.org/data/definitions/284.html

Red Hat OpenShift Enterprise 3.2, when multi-tenant SDN is enabled and a build is run in a namespace that would normally be isolated from pods in other namespaces, allows remote authenticated users to access network resources on restricted pods via an s2i build with a builder image that (1) contains ONBUILD commands or (2) does not contain a tar binary.

Weakness

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
