This vulnerability is due to a time-of-check, time-of-use (TOCTOU) race condition when an install query regarding an ISO image is performed during an install operation that uses an ISO image. An attacker could exploit this vulnerability by modifying an ISO image and then carrying out install requests in parallel. A successful exploit could allow the attacker to execute arbitrary code on an affected device.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/70400"}, {"timestamp": "2023-09-13T22:00:00Z", "date_only": false, "value": "2023-09-13T22:00:00.000+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2355", "record": "WID-SEC-W-2023-2355", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2023-09-13T22:00:00Z", "date_only": false, "value": "2023-09-13T22:00:00.000+00:00", "kind": "milestone", "label": "Published", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2355", "record": "WID-SEC-W-2023-2355", "field": "document.tracking.initial_release_date"}, {"timestamp": "2023-09-13T22:00:00Z", "date_only": false, "value": "2023-09-13T22:00:00.000+00:00", "kind": "other", "label": "Release date", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2355", "record": "WID-SEC-W-2023-2355", "field": "vulnerabilities.0.release_date"}, {"timestamp": "2023-09-13T22:00:00Z", "date_only": false, "value": "2023-09-13T22:00:00.000+00:00", "kind": "other", "label": "Updated", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2355", "record": "WID-SEC-W-2023-2355", "field": "document.tracking.current_release_date"}, {"timestamp": "2023-11-15T16:36:16.730Z", "date_only": false, "value": "2023-11-15T16:36:16.730906Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-20135", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2023-11-15T16:36:16.730Z", "date_only": false, "value": "2023-11-15T16:36:16.730906Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-20135", "record": "FKIE_CVE-2023-20135", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2023-12-13T01:20:28.354Z", "date_only": false, "value": "2023-12-13T01:20:28.354444Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-20135", "record": "GSD-2023-20135", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-01-25T16:57:47.716Z", "date_only": false, "value": "2024-01-25T16:57:47.716Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / cisco", "record": "CVE-2023-20135", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2024-01-25T17:15:31.443Z", "date_only": false, "value": "2024-01-25T17:15:31.443", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-20135", "record": "GSD-2023-20135", "field": "namespaces.nvd.nist.gov.cve.lastModified"}, {"timestamp": "2024-01-25T18:30:43Z", "date_only": false, "value": "2024-01-25T18:30:43Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-6V48-QPG5-FJ4M", "record": "GHSA-6V48-QPG5-FJ4M", "field": "modified"}, {"timestamp": "2024-05-10T23:26:36Z", "date_only": false, "value": "2024-05-10T23:26:36+00:00", "kind": "other", "label": "Document generated", "source": "csaf_cisco \u00b7 CISCO-SA-LNT-L9ZOKBZ5", "record": "CISCO-SA-LNT-L9ZOKBZ5", "field": "document.tracking.generator.date"}, {"timestamp": "2024-08-02T08:57:36.157Z", "date_only": false, "value": "2024-08-02T08:57:36.157Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2023-20135", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-08-15T17:58:27.102Z", "date_only": false, "value": "2024-08-15T17:58:27.102+00:00", "kind": "other", "label": "Document generated", "source": "csaf_certbund \u00b7 WID-SEC-W-2023-2355", "record": "WID-SEC-W-2023-2355", "field": "document.tracking.generator.date"}, {"timestamp": "2025-12-16T18:23:19.364Z", "date_only": false, "value": "2025-12-16T18:23:19.364Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2023-20135", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2025-12-16T18:23:19.364Z", "date_only": false, "value": "2025-12-16T18:23:19.364Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-20135", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T05:29:36.643Z", "date_only": false, "value": "2026-06-17T05:29:36.643", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-20135", "record": "FKIE_CVE-2023-20135", "field": "lastModified"}]}
