An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-40495 in the wild and no public exploit code.\n\nAffected product: Sap Netweaver Application Server Abap. 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-2021-40495/ (Markdown: https://insights.sbomify.com/CVE-2021-40495/index.md)","id":"CVE-2021-40495","markdown":"https://insights.sbomify.com/CVE-2021-40495/index.md","name":"CVE-2021-40495","record":{"aliases":["GHSA-c7v9-3364-rhjg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP NetWeaver ABAP","requires_auth":"none","summary":"An unauthorized attacker can degrade performance of SAP NetWeaver Application Server ABAP via a public service, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"netweaver_abap","vendor":"sap"},{"product":"netweaver_application_server_abap","vendor":"sap"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"description":"There are multiple Denial-of Service vulnerabilities in SAP NetWeaver Application Server for ABAP and ABAP Platform - versions 740, 750, 751, 752, 753, 754, 755.
