An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-11637 and fix it if it is affected.\n\nWhat it is: CVE-2020-11637 is a medium-severity denial of service vulnerability in B\u0026R Automation Runtime, published on 15 Oct 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-2020-11637 in the wild and no public exploit code.\n\nAffected product: B\u0026R Automation Runtime. 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-2020-11637/ (Markdown: https://insights.sbomify.com/CVE-2020-11637/index.md)","id":"CVE-2020-11637","markdown":"https://insights.sbomify.com/CVE-2020-11637/index.md","name":"CVE-2020-11637","record":{"aliases":["CVE-2020-10178","GHSA-7j7h-vfmh-v8jc"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Automation Runtime","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial of service in B\u0026R Automation Runtime via a memory leak in the TFTP service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"automation_runtime","vendor":"br-automation"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A memory leak in the TFTP service in B\u0026R Automation Runtime versions \u003cN4.26, \u003cN4.34, \u003cF4.45, \u003cE4.53, \u003cD4.63, \u003cA4.73 and prior could allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition.","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":"Automation Runtime TFTP Service DoS Vulnerability","id":"CVE-2020-11637","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Insufficient access control on Inter process communication,","id":"CVE-2020-11639"},"packages":[],"prev":{"headline":"Privilege escalation in Zscaler Client Connector for Windows","id":"CVE-2020-11635"},"products":["Automation Runtime"],"published":"2020-10-15","related":[{"cvss_score":9.8,"headline":"FTP uses unsecure encryption mechanisms","id":"CVE-2024-0323","kev_date_added":null,"published":"2024-02-05"},{"cvss_score":9.4,"headline":"B\u0026R Automation Runtime SNMP Authentication and Authorization Weakness","id":"CVE-2019-19108","kev_date_added":null,"published":"2020-04-20"},{"cvss_score":8.6,"headline":"Denial of service in B\u0026R Automation Runtime","id":"CVE-2023-3242","kev_date_added":null,"published":"2023-07-26"},{"cvss_score":8.6,"headline":"Denial of service vulnerability on Automation Runtime webserver","id":"CVE-2021-22275","kev_date_added":null,"published":"2022-05-13"},{"cvss_score":8.3,"headline":"Diffie-Hellman groups with insufficient strength used in SSL/TLS stack of B\u0026R Automation Runtime","id":"CVE-2024-5800","kev_date_added":null,"published":"2024-08-10"},{"cvss_score":6.1,"headline":"SDM Web interface vulnerable to XSS","id":"CVE-2023-6028","kev_date_added":null,"published":"2024-02-05"},{"cvss_score":6.1,"headline":"Reflected Cross-Site Scripting Vulnerabilities in Automation Runtime","id":"CVE-2022-4286","kev_date_added":null,"published":"2023-02-14"}],"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":["B\u0026R"]},"summary":"An unauthenticated attacker can cause a denial of service in B\u0026R Automation Runtime via a memory leak in the TFTP service.","url":"https://insights.sbomify.com/CVE-2020-11637/"}
