Prior to versions 1.4.5, 1.5.1, and 1.6.0, in the official apps/epics client tool on v1.6.0-rc1 (not in the generic BACnet RPM ACK decoder alone) a malicious BACnet/IP endpoint can reply to the EPICS tool\u2019s legitimate ReadPropertyMultiple request with a syntactically valid ReadPropertyMultiple-ACK that contains more heading properties than the tool\u2019s fixed local storage can hold. The response is decoded successfully and later consumed by ProcessRPMData(), which writes property values into a fixed global array using an unbounded linear index. This results in a reproducible global-buffer-overflow in apps/epics/main.c. This is a network-reachable memory corruption in the official epics tool\u2019s response-processing path. The root cause is that apps/epics treats a remotely supplied variable-length RPM property list as if it were a trusted, fixed-size local heading-property set. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-52786https://github.com/bacnet-stack/bacnet-stack/security/advisories/GHSA-c4q6-7827-mfg6https://github.com/bacnet-stack/bacnet-stack/pull/1366https://github.com/bacnet-stack/bacnet-stack/pull/1409#bacnet-stack#CVE_2026_52786#bot", "url": "https://infosec.exchange/users/cve/statuses/117605256155210106"}, {"timestamp": "2026-11-12T20:18:42.493Z", "date_only": false, "value": "2026-11-12T20:18:42.493", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-52786", "record": "FKIE_CVE-2026-52786", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-12T22:09:39.233Z", "date_only": false, "value": "2026-11-12T22:09:39.233", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-52786", "record": "FKIE_CVE-2026-52786", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-13T06:07:37.505Z", "anchors": {"origin": {"timestamp": "2026-11-12T19:59:45.264Z", "date_only": false, "value": "2026-11-12T19:59:45.264Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-52786", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-12T19:59:45.264Z", "date_only": false, "value": "2026-11-12T19:59:45.264Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-52786", "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": 36472.241657, "hours": 10.131178238055556, "days": 0.42213242658564815, "min_seconds": 36472.241657, "max_seconds": 36472.241657, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-12T19:59:45.264Z", "date_only": false, "value": "2026-11-12T19:59:45.264Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-52786", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-13T06:07:37.505Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
