It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-8484 and fix it if it is affected.\n\nWhat it is: CVE-2020-8484 is a high-severity missing authorization vulnerability in ABB 800xA for DCI, published on 29 Apr 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8484 in the wild and no public exploit code.\n\nAffected product: ABB 800xA for DCI. 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-2020-8484/ (Markdown: https://insights.sbomify.com/CVE-2020-8484/index.md)","id":"CVE-2020-8484","markdown":"https://insights.sbomify.com/CVE-2020-8484/index.md","name":"CVE-2020-8484","record":{"aliases":["GHSA-2x2x-f8f2-vqmf"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Industrial Control System","requires_auth":"low_privilege","summary":"Authenticated local attackers can inject data to read/write controllers or crash processes in ABB System 800xA for DCI.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"800xa","vendor":"abb"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-264","name":null}],"description":"Insufficient protection of the inter-process communication functions in ABB System 800xA for DCI (all published versions) enables an attacker authenticated on the local system to inject data, allowing reads and writes to the controllers or cause windows processes to crash.","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":"ABB System 800xA Inter process communication vulnerability - 800xA for DCI","id":"CVE-2020-8484","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"ABB System 800xA Inter process communication vulnerability - 800xA for Mod 300","id":"CVE-2020-8485"},"packages":[],"prev":{"headline":"ABB Device Library Wizard Information Disclosure Vulnerability","id":"CVE-2020-8482"},"products":["800xA for DCI"],"published":"2020-04-29","related":[{"cvss_score":7.8,"headline":"ABB System 800xA Inter process communication vulnerability - 800xA for Mod 300","id":"CVE-2020-8485","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":7.5,"headline":"AC 800M MMS - Denial of Service vulnerability in MMS communication","id":"CVE-2021-22277","kev_date_added":null,"published":"2022-04-01"}],"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":"2024-08-04","vendors":["ABB"]},"summary":"Authenticated local attackers can inject data to read/write controllers or crash processes in ABB System 800xA for DCI.","url":"https://insights.sbomify.com/CVE-2020-8484/"}
