A remote unauthenticated user can cause the network to be flooded leading to Denial of Service for actual network users. This is a high severity vulnerability as it allows an attacker to cause an outage of network. Dell recommends customers to upgrade at the earliest opportunity.\n\n","published_at":"2023-12-05T06:04:01.008000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-400"],"nvd_references":["https://www.dell.com/support/kbdoc/en-us/000220138/dsa-2023-278-dell-networking-os10-security-updates-for-uncontrolled-resource-consumption"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:34:40.382541Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"dell","vendor_name":"Dell","product_slug":"dell-networking-os10","product_name":"Dell Networking OS10","version_start":"10.5.5.5","version_start_inclusive":true,"version_end":"10.5.5.5","version_end_inclusive":true,"cpe23_uri":"cve5:dell:dell-networking-os10:10.5.5.5:10.5.5.5"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.dell.com/support/kbdoc/en-us/000220138/dsa-2023-278-dell-networking-os10-security-updates-for-uncontrolled-resource-consumption","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2023-12-05T06:04:01.008000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:29:24.974551Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:24.974551Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:24.974551Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:34:40.382541Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:34:40.382541Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:34:40.382541Z","label":"SSVC decision revised","source":"vulnrichment"}]}
