It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-11899 in the wild since at least 3 Mar 2022.\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-2020-11899/ (Markdown: https://insights.sbomify.com/CVE-2020-11899/index.md)","id":"CVE-2020-11899","markdown":"https://insights.sbomify.com/CVE-2020-11899/index.md","name":"CVE-2020-11899","record":{"aliases":["GHSA-6r3w-c7h6-wfhg"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Treck TCP/IP stack","requires_auth":"none","summary":"An out-of-bounds read in the Treck TCP/IP stack allows attackers to cause denial of service or disclose sensitive information via IPv6 packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wyse_5030_firmware","vendor":"dell"},{"product":"wyse_5050_all-in-one_firmware","vendor":"dell"},{"product":"wyse_7030_firmware","vendor":"dell"},{"product":"tcp\\/ip","vendor":"treck"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"The Treck TCP/IP stack before 6.0.1.66 has an IPv6 Out-of-bounds Read.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Treck TCP/IP stack Out-of-Bounds Read","id":"CVE-2020-11899","indexable":true,"kev":{"dateAdded":"2022-03-03","dueDate":"2022-03-17","knownRansomwareCampaignUse":"Unknown","product":"IPv6","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Treck TCP/IP stack","vulnerabilityName":"Treck TCP/IP stack Out-of-Bounds Read Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":11,"next":{"headline":"Use after free in n/a","id":"CVE-2020-11900"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2020-11898"},"products":["n/a"],"published":"2020-06-17","related":[],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"An out-of-bounds read in the Treck TCP/IP stack allows attackers to cause denial of service or disclose sensitive information via IPv6 packets.","url":"https://insights.sbomify.com/CVE-2020-11899/"}
