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-2017-1000230 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-2017-1000230/ (Markdown: https://insights.sbomify.com/CVE-2017-1000230/index.md)","id":"CVE-2017-1000230","markdown":"https://insights.sbomify.com/CVE-2017-1000230/index.md","name":"CVE-2017-1000230","record":{"aliases":["GHSA-58r9-jqc4-jgp3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Snap7 S7 protocol library","requires_auth":"none","summary":"An attacker can crash the Snap7 Server by sending unexpected input to the ItemCount field in S7 protocol functions, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"snap7_server","vendor":"snap7_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The Snap7 Server version 1.4.1 can be crashed when the ItemCount field of the ReadVar or WriteVar functions of the S7 protocol implementation in Snap7 are provided with unexpected input, thus resulting in denial of service attack.","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":"Denial of service in n/a","id":"CVE-2017-1000230","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in n/a","id":"CVE-2017-1000231"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2017-1000229"},"products":["n/a"],"published":"2017-11-17","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":"2024-09-16","vendors":["n/a"]},"summary":"An attacker can crash the Snap7 Server by sending unexpected input to the ItemCount field in S7 protocol functions, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2017-1000230/"}
