These vulnerabilities are due to a logic error that could occur when the affected software constructs and applies per-user-override rules. An attacker could exploit these vulnerabilities by connecting to a network through an affected device that has a vulnerable configuration. A successful exploit could allow the attacker to bypass the interface ACL and access resources that would should be protected.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/73344"}, {"timestamp": "2023-11-01T23:00:00Z", "date_only": false, "value": "2023-11-01T23:00:00.000+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2812", "record": "WID-SEC-W-2023-2812", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2023-11-01T23:00:00Z", "date_only": false, "value": "2023-11-01T23:00:00.000+00:00", "kind": "milestone", "label": "Published", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2812", "record": "WID-SEC-W-2023-2812", "field": "document.tracking.initial_release_date"}, {"timestamp": "2023-11-01T23:00:00Z", "date_only": false, "value": "2023-11-01T23:00:00.000+00:00", "kind": "other", "label": "Release date", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2812", "record": "WID-SEC-W-2023-2812", "field": "vulnerabilities.0.release_date"}, {"timestamp": "2023-11-01T23:00:00Z", "date_only": false, "value": "2023-11-01T23:00:00.000+00:00", "kind": "other", "label": "Updated", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2812", "record": "WID-SEC-W-2023-2812", "field": "document.tracking.current_release_date"}, {"timestamp": "2023-12-13T01:20:27.625Z", "date_only": false, "value": "2023-12-13T01:20:27.625572Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-20256", "record": "GSD-2023-20256", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-01-25T16:58:33.743Z", "date_only": false, "value": "2024-01-25T16:58:33.743Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / cisco", "record": "CVE-2023-20256", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2024-01-25T17:15:41.643Z", "date_only": false, "value": "2024-01-25T17:15:41.643", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-20256", "record": "GSD-2023-20256", "field": "namespaces.nvd.nist.gov.cve.lastModified"}, {"timestamp": "2024-08-02T09:05:36.885Z", "date_only": false, "value": "2024-08-02T09:05:36.885Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2023-20256", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-08-15T18:00:58.786Z", "date_only": false, "value": "2024-08-15T18:00:58.786+00:00", "kind": "other", "label": "Document generated", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2812", "record": "WID-SEC-W-2023-2812", "field": "document.tracking.generator.date"}, {"timestamp": "2024-11-21T21:44:33.524Z", "date_only": false, "value": "2024-11-21T21:44:33.524414Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-20256", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2024-11-21T21:44:33.524Z", "date_only": false, "value": "2024-11-21T21:44:33.524414Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-20256", "record": "FKIE_CVE-2023-20256", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2024-11-21T21:44:44.427Z", "date_only": false, "value": "2024-11-21T21:44:44.427Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2023-20256", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-11-21T21:44:44.427Z", "date_only": false, "value": "2024-11-21T21:44:44.427Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-20256", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2025-10-13T15:43:15Z", "date_only": false, "value": "2025-10-13T15:43:15+00:00", "kind": "other", "label": "Document generated", "source": "csaf_cisco \u00b7 CISCO-SA-ASAFTD-AC-ACL-BYPASS-BWD7Q6GB", "record": "CISCO-SA-ASAFTD-AC-ACL-BYPASS-BWD7Q6GB", "field": "document.tracking.generator.date"}, {"timestamp": "2026-08-11T19:33:44.513Z", "date_only": false, "value": "2026-08-11T19:33:44.513", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-20256", "record": "FKIE_CVE-2023-20256", "field": "lastModified"}]}
