Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-8520 in the wild and no public exploit code.\n\nAffected product: Hewlett Packard Enterprise Helion Eucalyptus. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2016-8520/ (Markdown: https://insights.sbomify.com/CVE-2016-8520/index.md)","id":"CVE-2016-8520","markdown":"https://insights.sbomify.com/CVE-2016-8520/index.md","name":"CVE-2016-8520","record":{"aliases":["GHSA-29jc-9wc9-6c78"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"HPE Helion Eucalyptus","requires_auth":"low_privilege","summary":"Authenticated users with S3 permissions can improperly access versioned data and ACLs due to incorrect permission checks in HPE Helion Eucalyptus.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hpe","cpe":[{"product":"eucalyptus","vendor":"eucalyptus"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-275","name":null}],"description":"HPE Helion Eucalyptus v4.3.0 and earlier does not correctly check IAM user's permissions for accessing versioned objects and ACLs.
