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-2021-45523 and fix it if it is affected.\n\nWhat it is: CVE-2021-45523 is a medium-severity memory corruption vulnerability in Netgear R7000 Firmware, published on 26 Dec 2021. 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-2021-45523 in the wild and no public exploit code.\n\nAffected product: Netgear R7000 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-2021-45523/ (Markdown: https://insights.sbomify.com/CVE-2021-45523/index.md)","id":"CVE-2021-45523","markdown":"https://insights.sbomify.com/CVE-2021-45523/index.md","name":"CVE-2021-45523","record":{"aliases":["GHSA-qmw2-f5xc-5j93"],"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 router","requires_auth":"low_privilege","summary":"An authenticated user can trigger a buffer overflow in NETGEAR R7000 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":"r7000_firmware","vendor":"netgear"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AC:L/AV:A/A:H/C:N/I:N/PR:L/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"NETGEAR R7000 devices before 1.0.9.42 are affected by a 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-2021-45523","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netgear:r7000_firmware","products":["netgear:r7000_firmware"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-45524"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2021-45522"},"products":["n/a"],"published":"2021-12-26","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-37235","kev_date_added":null,"published":"2022-09-23"},{"cvss_score":8.8,"headline":"Auth bypass in R7000","id":"CVE-2021-34977","kev_date_added":null,"published":"2022-01-13"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2021-31802","kev_date_added":null,"published":"2021-04-26"},{"cvss_score":8.4,"headline":"Command injection in n/a","id":"CVE-2024-35520","kev_date_added":null,"published":"2024-10-14"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-37234","kev_date_added":null,"published":"2022-09-22"},{"cvss_score":7.4,"headline":"Memory corruption in n/a","id":"CVE-2019-20758","kev_date_added":null,"published":"2020-04-16"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2021-45662","kev_date_added":null,"published":"2021-12-26"}],"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":"An authenticated user can trigger a buffer overflow in NETGEAR R7000 routers, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2021-45523/"}
