An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-43803 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/metal3-io/baremetal-operator (Go): affected all versions; fixed in 0.5.2, 0.6.2, 0.8.0\n- github.com/metal3-io/baremetal-operator (Go): affected all versions; fixed in 0.5.2\n- github.com/metal3-io/baremetal-operator (Go): affected all versions; fixed in 0.5.2\n- github.com/metal3-io/baremetal-operator (Go): affected from 0.6.0; fixed in 0.6.2\n- github.com/metal3-io/baremetal-operator (Go): affected from 0.6.0; fixed in 0.6.2\n- github.com/metal3-io/baremetal-operator (Go): affected from 0.7.0-rc.0; fixed in 0.8.0\n- github.com/metal3-io/baremetal-operator (Go): affected from 0.7.0-rc.0; fixed in 0.8.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-43803/ (Markdown: https://insights.sbomify.com/CVE-2024-43803/index.md)","id":"CVE-2024-43803","markdown":"https://insights.sbomify.com/CVE-2024-43803/index.md","name":"CVE-2024-43803","record":{"aliases":["GHSA-pqfh-xh7w-7h3p","GO-2024-3109"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Metal3 Bare Metal Operator","requires_auth":"high_privilege","summary":"An attacker with BMH creation rights can exfiltrate secrets from other namespaces by referencing them in host provisioning data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-653","name":"Improper Isolation or Compartmentalization"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Bare Metal Operator (BMO) implements a Kubernetes API for managing bare metal hosts in Metal3. The `BareMetalHost` (BMH) CRD allows the `userData`, `metaData`, and `networkData` for the provisioned host to be specified as links to Kubernetes Secrets. There are fields for both the `Name` and `Namespace` of the Secret, meaning that versions of the baremetal-operator prior to 0.8.0, 0.6.2, and 0.5.2 will read a `Secret` from any namespace. A user with access to create or edit a `BareMetalHost` can thus exfiltrate a `Secret` from another namespace by using it as e.g. the `userData` for provisioning some host (note that this need not be a real host, it could be a VM somewhere).\n\nBMO will only read a key with the name `value` (or `userData`, `metaData`, or `networkData`), so that limits the exposure somewhat. `value` is probably a pretty common key though. Secrets used by _other_ `BareMetalHost`s in different namespaces are always vulnerable. It is probably relatively unusual for anyone other than cluster administrators to have RBAC access to create/edit a `BareMetalHost`. This vulnerability is only meaningful, if the cluster has users other than administrators and users' privileges are limited to their respective namespaces.\n\nThe patch prevents BMO from accepting links to Secrets from other namespaces as BMH input. Any BMH configuration is only read from the same namespace only. The problem is patched in BMO releases v0.7.0, v0.6.2 and v0.5.2 and users should upgrade to those versions. Prior upgrading, duplicate the BMC Secrets to the namespace where the corresponding BMH is. After upgrade, remove the old Secrets. As a workaround, an operator can configure BMO RBAC to be namespace scoped for Secrets, instead of cluster scoped, to prevent BMO from accessing Secrets from other namespaces.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"BMO can expose particularly named secrets from other namespaces via BMH CRD","id":"CVE-2024-43803","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2024"},"n_packages":7,"n_references":7,"next":{"headline":"OS Command Injection via Port Scan Functionality in Roxy-WI","id":"CVE-2024-43804"},"packages":[{"ecosystem":"Go","fixed":["0.5.2","0.6.2","0.8.0"],"introduced":["0","0.6.0","0.7.0-rc.0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":"pkg:golang/github.com/metal3-io/baremetal-operator","source":"GO-2024-3109"},{"ecosystem":"Go","fixed":["0.5.2"],"introduced":["0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":null,"source":"GHSA-pqfh-xh7w-7h3p"},{"ecosystem":"Go","fixed":["0.5.2"],"introduced":["0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":"pkg:golang/github.com/metal3-io/baremetal-operator","source":"GHSA-pqfh-xh7w-7h3p"},{"ecosystem":"Go","fixed":["0.6.2"],"introduced":["0.6.0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":null,"source":"GHSA-pqfh-xh7w-7h3p"},{"ecosystem":"Go","fixed":["0.6.2"],"introduced":["0.6.0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":"pkg:golang/github.com/metal3-io/baremetal-operator","source":"GHSA-pqfh-xh7w-7h3p"},{"ecosystem":"Go","fixed":["0.8.0"],"introduced":["0.7.0-rc.0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":null,"source":"GHSA-pqfh-xh7w-7h3p"},{"ecosystem":"Go","fixed":["0.8.0"],"introduced":["0.7.0-rc.0"],"last_affected":[],"package":"github.com/metal3-io/baremetal-operator","purl":"pkg:golang/github.com/metal3-io/baremetal-operator","source":"GHSA-pqfh-xh7w-7h3p"}],"prev":{"headline":"heap-buffer-overflow in ins_typebuf() in Vim \u003c 9.1.0697","id":"CVE-2024-43802"},"products":["baremetal-operator"],"published":"2024-09-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-03","vendors":["metal3-io"]},"summary":"An attacker with BMH creation rights can exfiltrate secrets from other namespaces by referencing them in host provisioning data.","url":"https://insights.sbomify.com/CVE-2024-43803/"}
