Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-17533 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.accumulo:accumulo-master (Maven): affected from 1.5.0; fixed in 1.10.1\n- org.apache.accumulo:accumulo-master (Maven): affected from 1.5.0; fixed in 1.10.1\n- org.apache.accumulo:accumulo-master (Maven): affected from 2.0.0; fixed in 2.0.1\n- org.apache.accumulo:accumulo-master (Maven): affected from 2.0.0; fixed in 2.0.1\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-2020-17533/ (Markdown: https://insights.sbomify.com/CVE-2020-17533/index.md)","id":"CVE-2020-17533","markdown":"https://insights.sbomify.com/CVE-2020-17533/index.md","name":"CVE-2020-17533","record":{"aliases":["GHSA-grc3-8q8m-4j7c"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Accumulo","requires_auth":"low_privilege","summary":"Authenticated users with insufficient permissions can perform administrative actions like flushing tables or shutting down servers due to unchecked security function return values.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"accumulo","vendor":"apache"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-252","name":"Unchecked Return Value"}],"description":"Apache Accumulo versions 1.5.0 through 1.10.0 and version 2.0.0 do not properly check the return value of some policy enforcement functions before permitting an authenticated user to perform certain administrative operations.
