CVE-2017-8036
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in the Cloud Controller API in Cloud Foundry Foundation CAPI-release version 1.33.0 (only). The original fix for CVE-2017-8033 included in CAPI-release 1.33.0 introduces a regression that allows a space developer to execute arbitrary code on the Cloud Controller VM by pushing a specially crafted application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA regression in CAPI-release 1.33.0's Cloud Controller API allows authenticated space developers to execute arbitrary code on the Cloud Controller VM by pushing a specially crafted application. This vulnerability stems from the original fix for CVE-2017-8033 introducing a flaw that can be exploited.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify CAPI-release versionQuery the Cloud Foundry deployment metadata or bosh deployments to retrieve the version of the capi-release package. On the BOSH director, run 'bosh deployments' and inspect the release version for the capi release.Affected if The installed CAPI-release version is exactly 1.33.0
-
Verify Cloud Controller API is exposedCheck the Cloud Foundry router configuration and CC API route accessibility. Inspect the routing table or manifest to confirm the cc-api route is routable.Affected if The Cloud Controller API is accessible via network from authenticated user contexts
-
Confirm presence of space developer usersQuery the Cloud Foundry UAA or CC database for users with space developer roles. Use 'cf curl /v2/spaces/<guid>/developers' or check UAA user role assignments.Affected if There exist users granted the space developer role in any org/space
-
Check for application push capabilityVerify that authenticated space developers can push applications by reviewing org/space permissions and the allow_app_ssh setting.Affected if Space developers have the ability to push applications to any space
The environment is affected if CAPI-release version 1.33.0 is installed AND the Cloud Controller API is accessible to authenticated space developers who can push applications.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade CAPI-release to a version after 1.33.0 that addresses this regression; avoid deploying applications from untrusted sources until patched.
