An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-31206 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-31206/ (Markdown: https://insights.sbomify.com/CVE-2022-31206/index.md)","id":"CVE-2022-31206","markdown":"https://insights.sbomify.com/CVE-2022-31206/index.md","name":"CVE-2022-31206","record":{"aliases":["GHSA-fw2j-wpp5-8vp5"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Omron SYSMAC PLC","requires_auth":"none","summary":"Attackers can inject arbitrary machine code into Omron SYSMAC PLCs due to lack of cryptographic authentication on downloaded logic, enabling remote code execution.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nj101-1000_firmware","vendor":"omron"},{"product":"nj101-1020_firmware","vendor":"omron"},{"product":"nj101-9000_firmware","vendor":"omron"},{"product":"nj101-9020_firmware","vendor":"omron"},{"product":"nj301-1100_firmware","vendor":"omron"},{"product":"nj301-1200_firmware","vendor":"omron"},{"product":"nj501-1300_firmware","vendor":"omron"},{"product":"nj501-1320_firmware","vendor":"omron"},{"product":"nj501-1340_firmware","vendor":"omron"},{"product":"nj501-1400_firmware","vendor":"omron"},{"product":"nj501-1420_firmware","vendor":"omron"},{"product":"nj501-1500_firmware","vendor":"omron"},{"product":"nj501-1520_firmware","vendor":"omron"},{"product":"nj501-4300_firmware","vendor":"omron"},{"product":"nj501-4320_firmware","vendor":"omron"},{"product":"nj501-4400_firmware","vendor":"omron"},{"product":"nj501-4500_firmware","vendor":"omron"},{"product":"nj501-5300-1_firmware","vendor":"omron"},{"product":"nj501-5300_firmware","vendor":"omron"},{"product":"nx701-1600_firmware","vendor":"omron"},{"product":"nx701-1620_firmware","vendor":"omron"},{"product":"nx701-1700_firmware","vendor":"omron"},{"product":"nx701-1720_firmware","vendor":"omron"},{"product":"nx701-z600_firmware","vendor":"omron"},{"product":"nx701-z700_firmware","vendor":"omron"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"The Omron SYSMAC Nx product family PLCs (NJ series, NY series, NX series, and PMAC series) through 2022-005-18 lack cryptographic authentication. These PLCs are programmed using the SYMAC Studio engineering software (which compiles IEC 61131-3 conformant POU code to native machine code for execution by the PLC's runtime). The resulting machine code is executed by a runtime, typically controlled by a real-time operating system. The logic that is downloaded to the PLC does not seem to be cryptographically authenticated, allowing an attacker to manipulate transmitted object code to the PLC and execute arbitrary machine code on the processor of the PLC's CPU module in the context of the runtime. In the case of at least the NJ series, an RTOS and hardware combination is used that would potentially allow for memory protection and privilege separation and thus limit the impact of code execution. However, it was not confirmed whether these sufficiently segment the runtime from the rest of the RTOS.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in n/a","id":"CVE-2022-31206","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in n/a","id":"CVE-2022-31207"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2022-31205"},"products":["n/a"],"published":"2022-07-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can inject arbitrary machine code into Omron SYSMAC PLCs due to lack of cryptographic authentication on downloaded logic, enabling remote code execution.","url":"https://insights.sbomify.com/CVE-2022-31206/"}
