Software could allow an attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to improper initialization of a buffer. An attacker could exploit this vulnerability via any of the following methods: An authenticated, remote attacker could access the LLDP neighbor table via either the CLI or SNMP while the device is in a specific state. An unauthenticated, adjacent attacker could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then waiting for an administrator of the device or a network management system (NMS) managing the device to retrieve the LLDP neighbor table of the device via either the CLI or SNMP. An authenticated, adjacent attacker with SNMP read-only credentials or low privileges on the device CLI could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then accessing the LLDP neighbor table via either the CLI or SNMP. A successful exploit could allow the attacker to cause the affected device to crash, resulting in a reload of the device.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/29260"}, {"timestamp": "2021-10-13T00:00:00Z", "date_only": false, "value": "2021-10-13T00:00:00", "kind": "other", "label": "Date", "source": "variot \u00b7 VAR-202109-1039", "record": "VAR-202109-1039", "field": "sources_update_date.data.2.date"}, {"timestamp": "2021-10-25T18:09:00Z", "date_only": false, "value": "2021-10-25T18:09:00", "kind": "other", "label": "Date", "source": "variot \u00b7 VAR-202109-1039", "record": "VAR-202109-1039", "field": "sources_update_date.data.3.date"}, {"timestamp": "2022-05-05T07:09:49.939Z", "date_only": false, "value": "2022-05-05T07:09:49.939000Z", "kind": "other", "label": "Last update date", "source": "variot \u00b7 VAR-202109-1039", "record": "VAR-202109-1039", "field": "last_update_date"}, {"timestamp": "2022-05-24T19:15:38Z", "date_only": false, "value": "2022-05-24T19:15:38Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-H43V-FH8Q-W87R", "record": "GHSA-H43V-FH8Q-W87R", "field": "published"}, {"timestamp": "2023-05-22T18:57:00Z", "date_only": false, "value": "2023-05-22T18:57Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-34703", "record": "GSD-2021-34703", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-05-22T21:30:22Z", "date_only": false, "value": "2023-05-22T21:30:22Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-H43V-FH8Q-W87R", "record": "GHSA-H43V-FH8Q-W87R", "field": "modified"}, {"timestamp": "2023-12-13T01:23:14.382Z", "date_only": false, "value": "2023-12-13T01:23:14.382249Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-34703", "record": "GSD-2021-34703", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-05-10T23:08:22Z", "date_only": false, "value": "2024-05-10T23:08:22+00:00", "kind": "other", "label": "Document generated", "source": "csaf_cisco \u00b7 CISCO-SA-LLDP-DOS-SBNUHSJT", "record": "CISCO-SA-LLDP-DOS-SBNUHSJT", "field": "document.tracking.generator.date"}, {"timestamp": "2024-08-04T00:19:48.150Z", "date_only": false, "value": "2024-08-04T00:19:48.150Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-34703", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-11-07T21:40:38.420Z", "date_only": false, "value": "2024-11-07T21:40:38.420323Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2021-34703", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2024-11-07T21:40:38.420Z", "date_only": false, "value": "2024-11-07T21:40:38.420323Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-34703", "record": "FKIE_CVE-2021-34703", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2024-11-07T21:59:20.710Z", "date_only": false, "value": "2024-11-07T21:59:20.710Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-34703", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-11-07T21:59:20.710Z", "date_only": false, "value": "2024-11-07T21:59:20.710Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2021-34703", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T03:56:23.080Z", "date_only": false, "value": "2026-06-17T03:56:23.080", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-34703", "record": "FKIE_CVE-2021-34703", "field": "lastModified"}]}
