Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-19789 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-2019-19789/ (Markdown: https://insights.sbomify.com/CVE-2019-19789/index.md)","id":"CVE-2019-19789","markdown":"https://insights.sbomify.com/CVE-2019-19789/index.md","name":"CVE-2019-19789","record":{"aliases":["GHSA-9crr-pwpm-h268"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS PLC software","requires_auth":"low_privilege","summary":"A NULL pointer dereference in CODESYS PLC software allows attackers to cause a denial of service condition.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"plcwinnt","vendor":"codesys"},{"product":"runtime_toolkit","vendor":"codesys"},{"product":"sp_realtime_nt","vendor":"codesys"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"3S-Smart CODESYS SP Realtime NT before V2.3.7.28, CODESYS Runtime Toolkit 32 bit full before V2.4.7.54, and CODESYS PLCWinNT before V2.4.7.54 allow a NULL pointer dereference.","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":"Null dereference in n/a","id":"CVE-2019-19789","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2019-19790"},"packages":[],"prev":{"headline":"Security feature bypass in Opera for Android","id":"CVE-2019-19788"},"products":["n/a"],"published":"2019-12-20","related":[{"cvss_score":9.8,"headline":"Insecure default settings in CODESYS Runtime Toolkit 32 bit full and CODESYS PLCWinNT","id":"CVE-2022-31806","kev_date_added":null,"published":"2022-06-24"},{"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":"2024-08-05","vendors":["n/a"]},"summary":"A NULL pointer dereference in CODESYS PLC software allows attackers to cause a denial of service condition.","url":"https://insights.sbomify.com/CVE-2019-19789/"}
