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-2023-39248 in the wild and no public exploit code.\n\nAffected product: Dell Networking OS10. 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-2023-39248/ (Markdown: https://insights.sbomify.com/CVE-2023-39248/index.md)","id":"CVE-2023-39248","markdown":"https://insights.sbomify.com/CVE-2023-39248/index.md","name":"CVE-2023-39248","record":{"aliases":["GHSA-p2wr-4599-vv5h"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Dell Networking Switch","requires_auth":"none","summary":"Remote unauthenticated attackers can cause network flooding and denial of service on Dell OS10 switches configured with VLT and VRRP.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"networking_os10","vendor":"dell"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Dell OS10 Networking Switches running 10.5.2.x and above contain an Uncontrolled Resource Consumption (Denial of Service) vulnerability, when switches are configured with VLT and VRRP.
