An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-35141 exists.\n\nAffected packages and fixed versions:\n- ryu (PyPI): affected all versions up to 4.34; no fix listed\n- ryu (PyPI): affected all versions up to 4.34; no fix listed\n- ryu (PyPI): affected all versions up to 4.34; no fix listed\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-2020-35141/ (Markdown: https://insights.sbomify.com/CVE-2020-35141/index.md)","id":"CVE-2020-35141","markdown":"https://insights.sbomify.com/CVE-2020-35141/index.md","name":"CVE-2020-35141","record":{"aliases":["GHSA-5x64-925v-h4gv","PYSEC-2026-1878"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SDN controller","requires_auth":"none","summary":"Remote attackers can cause a denial of service via an infinite loop in the Faucet SDN Ryu controller's configuration parser.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ryu","vendor":"faucet"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-835","name":"Loop with Unreachable Exit Condition"}],"description":"An issue was discovered in OFPQueueGetConfigReply in parser.py in Faucet SDN Ryu version 4.34, allows remote attackers to cause a denial of service (DoS) (infinite loop).","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"FaucetSDN Ryu Denial of Service Vulnerability","id":"CVE-2020-35141","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":3,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-35144"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["4.34"],"package":"ryu","purl":null,"source":"GHSA-5x64-925v-h4gv"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["4.34"],"package":"ryu","purl":"pkg:pypi/ryu","source":"GHSA-5x64-925v-h4gv"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["4.34"],"package":"ryu","purl":"pkg:pypi/ryu","source":"PYSEC-2026-1878"}],"prev":{"headline":"FaucetSDN Ryu Denial of Service Vulnerability","id":"CVE-2020-35139"},"products":["n/a"],"published":"2023-08-11","related":[{"cvss_score":7.5,"headline":"FaucetSDN Ryu Denial of Service Vulnerability","id":"CVE-2020-35139","kev_date_added":null,"published":"2023-08-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-09","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via an infinite loop in the Faucet SDN Ryu controller's configuration parser.","url":"https://insights.sbomify.com/CVE-2020-35141/"}
