CVE-2026-41860
High · 8.8
CWE-326 Jun 4, 2026
Inadequate Encryption Strength in Cloud Foundry Foundation Bosh
CWE-326 in BOSH allows a local attacker to steal Basic-auth credentials or redirect UAA token requests via MITM. HttpRequestHelper#create_async_endpoint and #send_http_get_request_synchronous hard-code OpenSSL::SSL::VERIFY_NONE, enabling an attacker to intercept traffic between bosh-monitor and the BOSH director or UAA and steal credentials.
Affected versions:
- BOSH: all versions prior to v282.1.9 (inclusive); fixed in v282.1.9 or later

CWE-295 Jun 4, 2026
Improper Certificate Validation in Cloud Foundry Foundation Bosh
A network man-in-the-middle between nats-sync and the BOSH director can steal the director credentials (Basic auth header or UAA client secret) and can tamper with the VM list that is written into the NATS authorization file. Stolen credentials grant administrative director access. UsersSync#bosh_api_response_body builds a Net::HTTP client with verify_mode = OpenSSL::SSL::VERIFY_NONE for every director call (/info, /deployments, /deployments/<name>/vms).
Affected versions:
- BOSH: all versions prior to v282.1.9 (inclusive); fixed in v282.1.9 or later

CWE-78 Jun 4, 2026
OS Command Injection in Cloud Foundry Foundation Bosh
PackagePersister.validate_tgz builds "tar -tf #{tgz} 2>&1" where tgz = File.join(release_dir, 'packages', "#{name}.tgz") and name = package_meta['name'] comes directly from release.MF inside the uploaded tarball. The string is passed to Bosh::Common::Exec.sh, which executes via %x{} — i.e., /bin/sh -c. No Shellwords.escape is applied. The Models::Package Sequel validation (VALID_ID = /^[-0-9A-Za-z_+.]+$/i) would reject the name, but in create_package (lines 74–79) the shell-out in save_package_source_blob runs before package.save, so validation fires too late.
Affected versions:
- BOSH: all versions prior to v282.1.12 (inclusive); fixed in v282.1.12 or later

CWE-284 May 27, 2026
Compromised VM can make arbitrary blobstore deletes
AgentClient#handle_method (lines 264-303) processes every NATS reply. It calls inject_compile_log (line 273) on every response, which reads response['value']['result']['compile_log_id'] (line 332-338) and passes it to download_and_delete_blob. Separately, any response containing 'exception' goes through format_exception (lines 308-325), which reads exception['blobstore_id'] and also calls download_and_delete_blob. That helper (lines 344-349) calls ResourceManager#get_resource(blob_id) and, in an ensure block, ResourceManager#delete_resource(blob_id). ResourceManager (resource_manager.rb:62-70) calls blobstore.delete(id) on the single shared Director blobstore with no UUID-format check, no ownership check, and no namespace prefix.

CVE-2026-41009

CWE-22 May 27, 2026
Local Blobstore may allow arbitrary reads/deletes
When the director sends a long-running request (e.g. compile_package), the agent's reply JSON is consumed by AgentClient. inject_compile_log (line 332-339) reads response['value']['result']['compile_log_id'] and format_exception (line 318-325) reads exception['blobstore_id']; both pass the agent-supplied string unmodified to download_and_delete_blob(blob_id) (line 344-349), which calls @resource_manager.get_resource(blob_id) and, in an ensure block, @resource_manager.delete_resource(blob_id). Api::ResourceManager forwards the id straight to blobstore.get(id) / blobstore.delete(id). When the director is configured with the local blobstore provider, Blobstore::LocalClient#object_file_path(oid) is File.join(@blobstore_path, oid) (local_client.rb:54-56) with no normalisation, so oid = "../../jobs/director/config/director.yml" resolves outside the blobstore root.
