Description

Summary

The OpenChoreo API server (openchoreo-api) authorized requests to its exec and wirelogs endpoints against the project supplied by the caller in the request, rather than against the project that actually owns the target component. The target component was resolved by name only, and the authorization engine decided purely from the caller-supplied resource hierarchy — the component's real owning project was never checked. As a result, an authenticated user who holds a project-scoped exec or log-viewing grant on any single project could run commands in, and read the wirelogs of, components owned by other projects in the same namespace.

Impact

An authenticated tenant holding a project-scoped component:exec grant on just one project can execute arbitrary commands — including an interactive shell — inside the running pods of components owned by any other project in the same namespace. This exposes those workloads' environment variables and mounted Secrets (such as database credentials, API keys, and tokens), allows tampering with the workload, and enables further pivoting using the workload's own network position and credentials. The same flaw in the wirelogs endpoint lets a project-scoped wirelogs:view grant read any component's wirelogs in the namespace.

The blast radius is every component in the namespace, reachable from a single legitimate project grant. The boundary crossed is project-within-namespace: the request still pins the namespace, so the issue does not cross namespace boundaries. In effect this is a cross-project (cross-team) remote command-execution and data-access primitive available to any low-privileged tenant.

Patches

Fixed in 1.2.3 and 1.1.6. The fix aligns the exec and wirelogs endpoints with the pattern already used by other first-class component operations: the target component is fetched first and authorization is evaluated against its real owning project (comp.Spec.Owner.ProjectName) instead of the caller-supplied project query parameter.

Workarounds

If you cannot upgrade immediately:

  • Restrict component:exec and wirelogs:view grants to trusted operators only. Any holder of such a grant on any project can reach every component in the same namespace.
  • Where stronger isolation is required, separate sensitive components into their own namespaces, since the flaw does not cross namespace boundaries.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. Learn more on MITRE.

Incorrect Authorization

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. Learn more on MITRE.
