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-2021-3531 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2021-3531/ (Markdown: https://insights.sbomify.com/CVE-2021-3531/index.md)","id":"CVE-2021-3531","markdown":"https://insights.sbomify.com/CVE-2021-3531/index.md","name":"CVE-2021-3531","record":{"aliases":["DEBIAN-CVE-2021-3531","GHSA-wc6g-g56r-jp2f","UBUNTU-CVE-2021-3531"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ceph Storage RGW","requires_auth":"none","summary":"A flaw in Red Hat Ceph Storage RGW allows attackers to crash the service via a crafted GET request, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"ceph","vendor":"redhat"},{"product":"ceph_storage","vendor":"redhat"}],"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":[{"id":"CWE-617","name":"Reachable Assertion"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A flaw was found in the Red Hat Ceph Storage RGW in versions before 14.2.21.
