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-2020-11896 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-2020-11896/ (Markdown: https://insights.sbomify.com/CVE-2020-11896/index.md)","id":"CVE-2020-11896","markdown":"https://insights.sbomify.com/CVE-2020-11896/index.md","name":"CVE-2020-11896","record":{"aliases":["GHSA-hwgx-cxhm-g3q3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Treck TCP/IP stack","requires_auth":"none","summary":"A memory corruption vulnerability in the Treck TCP/IP stack allows remote attackers to execute arbitrary code via IPv4 tunneling.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tcp\\/ip","vendor":"treck"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The Treck TCP/IP stack before 6.0.1.66 allows Remote Code Execution, related to IPv4 tunneling.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-07-21","github_poc":2,"max_poc_stars":10,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-07-21T03:38:31Z","kind":"github_poc","ref":"https://github.com/Fans0n-Fan/Treck20-Related","stars":10,"title":"PoC for CVE-2020-11896 Treck TCP/IP stack and device asset investigation"},{"date":"2022-11-30T18:44:25Z","kind":"github_poc","ref":"https://github.com/0xkol/ripple20-digi-connect-exploit","stars":10,"title":"RCE exploit for CVE-2020-11896 (Ripple20 IP-in-IP Heap Overflow Vulnerability) targeting Digi Connect ME 9210"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2020-11896","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":11,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-11897"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-11895"},"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-2020-11897","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A memory corruption vulnerability in the Treck TCP/IP stack allows remote attackers to execute arbitrary code via IPv4 tunneling.","url":"https://insights.sbomify.com/CVE-2020-11896/"}
