An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-12516 and fix it if it is affected.\n\nWhat it is: CVE-2020-12516 is a high-severity denial of service vulnerability in WAGO 750-331/xxx-xxx, published on 10 Dec 2020. 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-2020-12516 in the wild and no public exploit code.\n\nAffected product: WAGO 750-331/xxx-xxx. 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-2020-12516/ (Markdown: https://insights.sbomify.com/CVE-2020-12516/index.md)","id":"CVE-2020-12516","markdown":"https://insights.sbomify.com/CVE-2020-12516/index.md","name":"CVE-2020-12516","record":{"aliases":["GHSA-wm2q-rjqh-v4ff"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WAGO PLC","requires_auth":"none","summary":"Attackers can cause a denial of service on WAGO PLCs by exploiting a vulnerability in older firmware versions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"750-331_firmware","vendor":"wago"},{"product":"750-352_firmware","vendor":"wago"},{"product":"750-829_firmware","vendor":"wago"},{"product":"750-831_firmware","vendor":"wago"},{"product":"750-852_firmware","vendor":"wago"},{"product":"750-880_firmware","vendor":"wago"},{"product":"750-881_firmware","vendor":"wago"},{"product":"750-882_firmware","vendor":"wago"},{"product":"750-885_firmware","vendor":"wago"},{"product":"750-889_firmware","vendor":"wago"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Older firmware versions (FW1 up to FW10) of the WAGO PLC family 750-88x and 750-352 are vulnerable for a special 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":"WAGO: PLC families 750-88x and 750-352 prone to DoS attack","id":"CVE-2020-12516","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in AXC F 1152 (1151412)","id":"CVE-2020-12517"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-12515"},"products":["750-331/xxx-xxx","750-352","750-829","750-831/xxx-xxx","750-852","750-880/xxx-xxx","750-881","750-882","750-885","750-889"],"published":"2020-12-10","related":[{"cvss_score":4.9,"headline":"WAGO: DoS in multiple versions of multiple products","id":"CVE-2023-1619","kev_date_added":null,"published":"2023-06-26"},{"cvss_score":4.9,"headline":"WAGO: DoS in multiple products in multiple versions using Codesys","id":"CVE-2023-1620","kev_date_added":null,"published":"2023-06-26"}],"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":"2024-09-16","vendors":["WAGO"]},"summary":"Attackers can cause a denial of service on WAGO PLCs by exploiting a vulnerability in older firmware versions.","url":"https://insights.sbomify.com/CVE-2020-12516/"}
