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-2020-17528 in the wild and no public exploit code.\n\nAffected product: Apache NuttX (incubating). 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-2020-17528/ (Markdown: https://insights.sbomify.com/CVE-2020-17528/index.md)","id":"CVE-2020-17528","markdown":"https://insights.sbomify.com/CVE-2020-17528/index.md","name":"CVE-2020-17528","record":{"aliases":["GHSA-36mq-qwm2-6rpp"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NuttX RTOS","requires_auth":"none","summary":"An attacker can corrupt memory and potentially execute code or cause denial of service by sending malicious TCP packets with invalid urgent data pointers to Apache NuttX.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nuttx","vendor":"apache"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Out-of-bounds Write vulnerability in TCP stack of Apache NuttX (incubating) versions up to and including 9.1.0 and 10.0.0 allows attacker to corrupt memory by supplying arbitrary urgent data pointer offsets within TCP packets including beyond the length of the packet.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache NuttX (incubating) Out of Bound Write from invalid TCP Urgent length","id":"CVE-2020-17528","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Apache NuttX (incubating) Out of Bound Write from invalid fragmentation offset value specified in the IP header","id":"CVE-2020-17529"},"packages":[],"prev":{"headline":"Apache Tomcat: Request header mix-up between HTTP/2 streams","id":"CVE-2020-17527"},"products":["Apache NuttX (incubating)"],"published":"2020-12-09","related":[{"cvss_score":9.8,"headline":"Apache NuttX RTOS: tools/bdf-converter.: tools/bdf-converter: Fix loop termination condition.","id":"CVE-2025-47868","kev_date_added":null,"published":"2025-06-16"},{"cvss_score":9.8,"headline":"Apache NuttX RTOS: examples/xmlrpc: Fix calls buffers size.","id":"CVE-2025-47869","kev_date_added":null,"published":"2025-06-16"},{"cvss_score":9.8,"headline":"Apache NuttX RTOS: NuttX Bluetooth Stack HCI and UART DoS/RCE Vulnerabilities.","id":"CVE-2025-35003","kev_date_added":null,"published":"2025-05-26"},{"cvss_score":9.8,"headline":"malloc, realloc and memalign implementations are vulnerable to integer wrap-arounds","id":"CVE-2021-26461","kev_date_added":null,"published":"2021-06-21"},{"cvss_score":9.8,"headline":"Apache NuttX (incubating) Out of Bound Write from invalid fragmentation offset value specified in the IP header","id":"CVE-2020-17529","kev_date_added":null,"published":"2020-12-09"},{"cvss_score":9.8,"headline":"Null dereference in Apache NuttX (incubating)","id":"CVE-2020-1939","kev_date_added":null,"published":"2020-05-12"}],"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":"2025-02-13","vendors":["Apache Software Foundation"]},"summary":"An attacker can corrupt memory and potentially execute code or cause denial of service by sending malicious TCP packets with invalid urgent data pointers to Apache NuttX.","url":"https://insights.sbomify.com/CVE-2020-17528/"}
