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-2022-31806 in the wild and no public exploit code.\n\nAffected product: CODESYS PLCWinNT. 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-2022-31806/ (Markdown: https://insights.sbomify.com/CVE-2022-31806/index.md)","id":"CVE-2022-31806","markdown":"https://insights.sbomify.com/CVE-2022-31806/index.md","name":"CVE-2022-31806","record":{"aliases":["GHSA-796c-7jw3-fwpp"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS PLC Runtime","requires_auth":"none","summary":"Attackers can access PLC controllers without authentication because password protection is disabled by default in CODESYS Runtime Toolkit and PLCWinNT.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"plcwinnt","vendor":"codesys"},{"product":"runtime_toolkit","vendor":"codesys"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"In CODESYS V2 PLCWinNT and Runtime Toolkit 32 in versions prior to V2.4.7.57 password protection is not enabled by default and there is no information or prompt to enable password protection at login in case no password is set at the controller.","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":"Insecure default settings in CODESYS Runtime Toolkit 32 bit full and CODESYS PLCWinNT","id":"CVE-2022-31806","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"misconfiguration","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Other in Building X - Security Manager Edge Controller (ACC-AP)","id":"CVE-2022-31807"},"packages":[],"prev":{"headline":"Insecure transmission of credentials","id":"CVE-2022-31805"},"products":["CODESYS PLCWinNT","CODESYS Runtime Toolkit 32 bit full"],"published":"2022-06-24","related":[{"cvss_score":8.8,"headline":"CODESYS Runtime System prone to heap based buffer overflow","id":"CVE-2022-32137","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":8.8,"headline":"CODESYS runtime system prone to denial of service due to Unexpected Sign Extension","id":"CVE-2022-32138","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":8.8,"headline":"CODESYS runtime system prone to directory acces","id":"CVE-2022-32143","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":8.1,"headline":"CODESYS runtime system prone to file deletion due to improper error handling","id":"CVE-2022-1965","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":8.1,"headline":"CODESYS runtime system prone to denial of service due to use of out of range pointer","id":"CVE-2022-32142","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":7.5,"headline":"CODESYS V2 runtime: unauthenticated invalid requests may result in denial-of-service","id":"CVE-2021-34593","kev_date_added":null,"published":"2021-10-26"}],"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":"2024-09-17","vendors":["CODESYS"]},"summary":"Attackers can access PLC controllers without authentication because password protection is disabled by default in CODESYS Runtime Toolkit and PLCWinNT.","url":"https://insights.sbomify.com/CVE-2022-31806/"}
