An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22275 and fix it if it is affected.\n\nWhat it is: CVE-2021-22275 is a high-severity denial of service vulnerability in B\u0026R Automation Automation Runtime webserver, published on 13 May 2022. 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-2021-22275 in the wild and no public exploit code.\n\nAffected product: B\u0026R Automation Automation Runtime webserver. 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-2021-22275/ (Markdown: https://insights.sbomify.com/CVE-2021-22275/index.md)","id":"CVE-2021-22275","markdown":"https://insights.sbomify.com/CVE-2021-22275/index.md","name":"CVE-2021-22275","record":{"aliases":["GHSA-r593-v4g4-3636"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"B\u0026R Automation Runtime","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial of service on B\u0026R Automation Runtime devices via a buffer overflow in the webserver.","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":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Overflow vulnerability in B\u0026R Automation Runtime webserver allows an unauthenticated network-based attacker to stop the cyclic program on the device and cause a denial of service.","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 vulnerability on Automation Runtime webserver","id":"CVE-2021-22275","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"free@home System Access Point FW integrity check can be bypassed.","id":"CVE-2021-22276"},"packages":[],"prev":{"headline":"ControlTouch Cloud Service vulnerability: Serial Number can be misused during commissioning phase.","id":"CVE-2021-22272"},"products":["Automation Runtime webserver"],"published":"2022-05-13","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":8.3,"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":"2024-08-03","vendors":["B\u0026R Automation"]},"summary":"An unauthenticated attacker can cause a denial of service on B\u0026R Automation Runtime devices via a buffer overflow in the webserver.","url":"https://insights.sbomify.com/CVE-2021-22275/"}
