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-2020-11900 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-11900/ (Markdown: https://insights.sbomify.com/CVE-2020-11900/index.md)","id":"CVE-2020-11900","markdown":"https://insights.sbomify.com/CVE-2020-11900/index.md","name":"CVE-2020-11900","record":{"aliases":["GHSA-5738-q2rr-3w4x"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Treck TCP/IP stack","requires_auth":"none","summary":"A double-free vulnerability in the Treck TCP/IP stack allows attackers to execute arbitrary code or cause denial of service via IPv4 tunneling.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tcp\\/ip","vendor":"treck"}],"cvss":{"score":8.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"The Treck TCP/IP stack before 6.0.1.41 has an IPv4 tunneling Double Free.","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":"Use after free in n/a","id":"CVE-2020-11900","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2020"},"n_packages":0,"n_references":11,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-11901"},"packages":[],"prev":{"headline":"Treck TCP/IP stack Out-of-Bounds Read","id":"CVE-2020-11899"},"products":["n/a"],"published":"2020-06-17","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2020-25066","kev_date_added":null,"published":"2020-12-22"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2020-11896","kev_date_added":null,"published":"2020-06-17"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2020-11897","kev_date_added":null,"published":"2020-06-17"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-11910","kev_date_added":null,"published":"2020-06-17"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2020-11898","kev_date_added":null,"published":"2020-06-17"},{"cvss_score":9.1,"headline":"The Treck TCP/IP stack before 6.0.1.66 has an IPv4 Integer Underflow.","id":"CVE-2020-11909","kev_date_added":null,"published":"2020-06-17"},{"cvss_score":9,"headline":"Memory corruption in n/a","id":"CVE-2020-11901","kev_date_added":null,"published":"2020-06-17"}],"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":["n/a"]},"summary":"A double-free vulnerability in the Treck TCP/IP stack allows attackers to execute arbitrary code or cause denial of service via IPv4 tunneling.","url":"https://insights.sbomify.com/CVE-2020-11900/"}
