In OneDev before version 4.0.3, the application's BasePage registers an AJAX event listener (`AbstractPostAjaxBehavior`) in all pages other than the login page. This listener decodes and deserializes the `data` query parameter. We can access this listener by submitting a POST request to any page. This issue may lead to `post-auth RCE` This endpoint is subject to authentication and, therefore, requires a valid user to carry on the attack. This issue was addressed in 4.0.3 by encrypting serialization payload with secrets only known to server.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/22228"}, {"timestamp": "2021-01-21T15:21:00Z", "date_only": false, "value": "2021-01-21T15:21Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-21247", "record": "GSD-2021-21247", "field": "namespaces.nvd.nist.gov.lastModifiedDate", "linked_record": true}, {"timestamp": "2023-12-13T01:23:11.365Z", "date_only": false, "value": "2023-12-13T01:23:11.365399Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-21247", "record": "GSD-2021-21247", "field": "gsd.osvSchema.modified", "linked_record": true}, {"timestamp": "2024-08-03T18:09:14.990Z", "date_only": false, "value": "2024-08-03T18:09:14.990Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "cve-2021-21247", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-03T18:09:14.990Z", "date_only": false, "value": "2024-08-03T18:09:14.990Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "cve-2021-21247", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T03:35:07.370Z", "date_only": false, "value": "2026-06-17T03:35:07.370", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-21247", "record": "FKIE_CVE-2021-21247", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-12T20:37:16.927Z", "anchors": {"origin": {"timestamp": "2021-01-15T20:10:40Z", "date_only": false, "value": "2021-01-15T20:10:40.000Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "cve-2021-21247", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2021-01-15T20:10:40Z", "date_only": false, "value": "2021-01-15T20:10:40.000Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "cve-2021-21247", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 183774396.927541, "hours": 51048.44359098361, "days": 2127.01848295765, "min_seconds": 183774396.927541, "max_seconds": 183774396.927541, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2021-01-15T20:10:40Z", "date_only": false, "value": "2021-01-15T20:10:40.000Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "cve-2021-21247", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-12T20:37:16.927Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
