It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-20764 and fix it if it is affected.\n\nWhat it is: CVE-2019-20764 is a medium-severity memory corruption vulnerability in Netgear R7800 Firmware, published on 16 Apr 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-20764 in the wild and no public exploit code.\n\nAffected product: Netgear R7800 Firmware. 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-2019-20764/ (Markdown: https://insights.sbomify.com/CVE-2019-20764/index.md)","id":"CVE-2019-20764","markdown":"https://insights.sbomify.com/CVE-2019-20764/index.md","name":"CVE-2019-20764","record":{"aliases":["GHSA-7ch3-c2vf-pvjm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR R7800 router","requires_auth":"high_privilege","summary":"An authenticated user can trigger a stack-based buffer overflow on NETGEAR R7800 routers, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"r7800_firmware","vendor":"netgear"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AC:L/AV:A/A:H/C:H/I:H/PR:H/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"NETGEAR R7800 devices before 1.0.2.52 are affected by a stack-based buffer overflow by an authenticated user.","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":"Memory corruption in n/a","id":"CVE-2019-20764","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netgear:r7800_firmware","products":["netgear:r7800_firmware"],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2019-20765"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2019-20763"},"products":["n/a"],"published":"2020-04-16","related":[{"cvss_score":9.4,"headline":"Other in n/a","id":"CVE-2020-11790","kev_date_added":null,"published":"2020-04-15"},{"cvss_score":8.8,"headline":"Misconfiguration in n/a","id":"CVE-2018-21158","kev_date_added":null,"published":"2020-04-27"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-20706","kev_date_added":null,"published":"2020-04-16"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2019-20707","kev_date_added":null,"published":"2020-04-16"},{"cvss_score":8.3,"headline":"Command injection in n/a","id":"CVE-2021-45623","kev_date_added":null,"published":"2021-12-26"},{"cvss_score":8,"headline":"Command injection in n/a","id":"CVE-2018-21101","kev_date_added":null,"published":"2020-04-23"},{"cvss_score":7.6,"headline":"Command injection in n/a","id":"CVE-2018-21099","kev_date_added":null,"published":"2020-04-27"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"An authenticated user can trigger a stack-based buffer overflow on NETGEAR R7800 routers, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2019-20764/"}
