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-2021-45573 and fix it if it is affected.\n\nWhat it is: CVE-2021-45573 is a high-severity memory corruption vulnerability in Netgear R6260 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-2021-45573 in the wild and no public exploit code.\n\nAffected product: Netgear R6260 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-2021-45573/ (Markdown: https://insights.sbomify.com/CVE-2021-45573/index.md)","id":"CVE-2021-45573","markdown":"https://insights.sbomify.com/CVE-2021-45573/index.md","name":"CVE-2021-45573","record":{"aliases":["GHSA-r2vh-7p3c-jgwf"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"none","summary":"Unauthenticated attackers can trigger a stack-based buffer overflow in NETGEAR routers to execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac2100_firmware","vendor":"netgear"},{"product":"ac2400_firmware","vendor":"netgear"},{"product":"ac2600_firmware","vendor":"netgear"},{"product":"r6260_firmware","vendor":"netgear"},{"product":"r6700_firmware","vendor":"netgear"},{"product":"r6800_firmware","vendor":"netgear"},{"product":"r6900_firmware","vendor":"netgear"},{"product":"r7450_firmware","vendor":"netgear"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:L/AV:A/A:L/C:H/I:H/PR:N/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker.
