They utilize the Omron FINS (9600/TCP) protocol for engineering purposes, including downloading projects and control logic to the PLC. This protocol has authentication flaws as reported in FSCT-2022-0057. Control logic is downloaded to PLC volatile memory using the FINS Program Area Read and Program Area Write commands or to non-volatile memory using other commands from where it can be loaded into volatile memory for execution. The logic that is loaded into and executed from the user program area exists in compiled object code form. Upon execution, these object codes are first passed to a dedicated ASIC that determines whether the object code is to be executed by the ASIC or the microprocessor. In the former case, the object code is interpreted by the ASIC whereas in the latter case the object code is passed to the microprocessor for object code interpretation by a ROM interpreter. In the abnormal case where the object code cannot be handled by either, an abnormal condition is triggered and the PLC is halted. The logic that is downloaded to the PLC does not seem to be cryptographically authenticated, thus allowing an attacker to manipulate transmitted object code to the PLC and either execute arbitrary object code commands on the ASIC or on the microprocessor interpreter."}, {"lang": "es", "value": "Los PLC de la familia de productos SYSMAC Cx de Omron (series CS, CJ y CP) versiones hasta 18-05-2022, carecen de autenticaci\u00f3n criptogr\u00e1fica. Usan el protocolo FINS (9600/TCP) de Omron para fines de ingenier\u00eda, incluida la descarga de proyectos y l\u00f3gica de control al PLC. Este protocolo presenta fallos de autenticaci\u00f3n, como es indicado en el documento FSCT-2022-0057. La l\u00f3gica de control es descargada en la memoria vol\u00e1til del PLC Usando los comandos FINS Program Area Read y Program Area Write o en la memoria no vol\u00e1til Usando otros comandos desde donde puede ser cargado en la memoria vol\u00e1til para su ejecuci\u00f3n. La l\u00f3gica que es cargada y ejecutada desde el \u00e1rea de programa de usuario se presenta en forma de c\u00f3digo objeto compilado. Al ejecutarse, estos c\u00f3digos objeto son pasados primero a un ASIC dedicado que determina si el c\u00f3digo objeto debe ser ejecutado por el ASIC o por el microprocesador. En el primer caso, el c\u00f3digo objeto es interpretado por el ASIC, mientras que en el segundo caso el c\u00f3digo objeto es pasado al microprocesador para que sea interpretado por un int\u00e9rprete ROM. En el caso anormal en el que el c\u00f3digo objeto no puede ser manejado por ninguno de los dos, es desencadenada una condici\u00f3n anormal y el PLC es detenido. La l\u00f3gica que es descargada en el PLC no parece estar autenticada criptogr\u00e1ficamente, lo que permite a un atacante manipular el c\u00f3digo objeto transmitido al PLC y ejecutar comandos de c\u00f3digo objeto arbitrarios en el ASIC o en el int\u00e9rprete del microprocesador.\n"}], "lastModified": "2022-08-04T15:01:23.993", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:sysmac_cs1_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DC0EDECA-0697-4BF1-AC39-7DAEAFA79FE5", "versionEndExcluding": "4.1"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:sysmac_cs1:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "6F4E42A1-A6A5-4590-A369-C3E11C55979B"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:sysmac_cj2m_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FC2E363E-0118-4CA4-BD97-6C4FE939BA3E", "versionEndExcluding": "2.1"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:sysmac_cj2m:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "4EC6E3CB-486B-4C41-87D7-BF16D9B9FA74"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:sysmac_cj2h_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "464F762D-50B7-4BC7-87B8-C6E0CDBB05DA", "versionEndExcluding": "1.5"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:sysmac_cj2h:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "179BC3C6-8530-4680-8DAA-B8734C3F088A"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:sysmac_cp1e_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6C2FE1EA-5A52-4245-8F66-60A88F3C5E5C", "versionEndExcluding": "1.30"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:sysmac_cp1e:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "4A3E5CC5-3B48-4CD0-8CE0-F12AA0A8A1CA"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:sysmac_cp1h_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9846BE46-9506-4434-BAA6-13A8AF687EC5", "versionEndExcluding": "1.30"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:sysmac_cp1h:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "1334C61E-D200-427B-833E-5FB538930F80"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:sysmac_cp1l_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3AAB91A7-28FD-4462-AD62-40A010D3FD33", "versionEndExcluding": "1.10"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:sysmac_cp1l:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "E74FC37C-0054-49E8-92CB-7BCF903D12C6"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:omron:cp1w-cif41_firmware:-:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "99A34BA8-7D88-4D08-A8F0-99570A397299"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:omron:cp1w-cif41:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "83911864-386F-40A2-BB2D-7E3443E3EDB8"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "cve@mitre.org"}
